If you have any problems with the meter, refer to the maintenance and troubleshooting sections of this manual.If you need further assistance, contact your local Omega Representative or contact the Omega customer service department by telephone, fax, or email for advice.2Operation2.1PrincipleThe Omega FTB500 Series of Low Flowrate Meters has been developed to meet the need for a low flow measurement device for use with low to moderate viscosity clean liquids and for gas measurement applications.The Omega FTB500 Series of Low Flowrate Meters is a family of low flow rate measurement devices whose design is based on a Pelton Wheel-like rotor. The measured fluid is directed tangentially through a velocity nozzle against the rotor causing it to spin. The pickup coil senses the spinning motion of the rotor through the housing and converts it into a pulsing electrical signal. Summation of the pulsing electrical signal relates directly to the total flow, while the frequency is related to the flow rate.2.2Precautions♦Do not drop the meter. Dropping the meter may result in damage to the meter housing and/or internals.♦Do not operate the meter at flowrates greater than the maximum flowrate marked on the meter. Operating atflowrates greater than the maximum flowrate may over-spin the meter. Over-spinning may result in damage tothe meter.CAUTION:Avoid over-spinning the meter. Over-spinning the meter may result in damage to the meter internals and lead to meterfailure.3 InstallationUpon receipt of the flowmeter carefully inspected it, checking for any indications of damage which may have occurred during shipment. Inspect all packing material carefully for parts or components which may have been packed with the shipment. Refer to the packing list/invoice for a detailed list of items included in the shipment.3.1 General PipingThe Omega FTB500 Series of Low Flowrate Meters is capable of sensing fluid flow in one direction only. The meter housing is marked by a flow direction arrow to indicate the direction of flow through the meter. The meter must be installed in the piping in the correct orientation to ensure the most accurate and reliable operation. Care should be taken in the proper selection of the mating fittings. Size, type of material, and pressure rating should be the same as the flowmeter supplied.When it is expected that flow will be intermittent, the meter should not be mounted at a low point in the piping system. Solids which settle or congeal in the meter may affect meter performance.In order to achieve optimum electrical signal output from the flowmeter, due consideration must be given to its isolation from ambient electrical interference such as nearby motors, trans-formers, and solenoids.A typical flowmeter installation is shown below:Blocking and Bypass valves should be installed if it is necessary to do preventive maintenance on the flowmeter without shutting down the flow system. The Bypass valve can be opened before the Blocking valves are closed allowing the flow to continue while removing the turbine flowmeter for service.BYPASS RUN METER RUNIMPORTANT: All flow lines should be purged prior to installing themeter. To prevent possible damage to the meter, install themeter ONLY in flow lines that are clean and free of debris.Upon initial start-up of the system a spool piece should be installed in place of the flowmeter so that purging of the system can be performed to remove all particle debris which could cause damage to the meter internals. In applications where meter flushing is required after meter service, care should be taken as to not over-spin the meter, as severe meter damage may occur.CAUTION:Avoid over-spinning the meter. Over-spinning the meter may result in damage to the meter internals and lead to meterfailure.3.2Strainers/FiltersThe Omega FTB500 Series of Low Flowrate Meters is designed for use in a clean fluid service. However, the service fluid may carry some particulate material which would need to be removed before reaching the flowmeter. Under these conditions a strainer/filter may be required to reduce the potential hazard of fouling or damage that may be caused by foreign matter.METER SIZE MESH SIZE PARTICLE SIZE(Maximum)¼" to ½"100 .00555/" to 1¼"70 .00881½" to 3"40 .015If a strainer/filter is required in the system, it should be located upstream of the flowmeter taking care that the proper minimum distance is kept between the strainer and flowmeter.3.3Installation KitsInstallation kits for the Omega FTB500 Series of Low Flowrate Meters consist of two lengths of appropriate tubing cut to a length appropriate for the upstream and downstream straight pipe run with appropriate end fittings.4Maintenance4.1GeneralPreventive maintenance for the Omega FTB500 Series of LowFlowrate Meters consists of a thorough general inspection.Remove the meter from the service line and take to a clean workarea.

Any num-ber of decades from one to eleven is available in a choice of accuracies.The Omega DB decade box is a precision resis-tance source with excellent characteristics of stabil-ity, temperature coefficient, power coefficient, and frequency response.The Omega DB Series employs very-low-resistance switches with silver alloy contacts. A special design keeps zero resistance to less than 1 mΩ per decade. Self cleaning keeps the silver contacts from becom-ing tarnished when unused, or when only low cur-rents are passed through them. This is most often the case when only minute test currents are drawn by digital multimeters or other test instruments. Contact resistance is stable and remains low and repeatable. High-quality gold-plated tellurium-copper binding posts serve to minimize the thermal emf effects which would artificially reflect a change in dc resistance measure-ments. All other conductors within the instrument, as well as the solder employed, contain no metals or junc-tions that could contribute to thermal emf problems.The standard models offer a choice of one through eleven decades. The panels are clearly labeled show-ing the step size and maximum voltage and current limitations for each decade.With a resolution as low as 1 mΩ and a maximum available resistance of over 111 MΩ, the Omega DB series may be used for exacting precision measure-ment applications requiring high accuracy, good sta-bility, and low zero-resistance. They can be used as components of dc and ac bridges, for calibration, as transfer standards, and as RTD simulators.The Omega DB Series may be rack-mounted to serve as components in measurement and control sys-tems.Figure 1.1. DBX Series High Accuracy Decade BoxChapter 2SPECIFICATIONSFor convenience to the user, the pertinent specifications are given in an OPERATING GUIDE affixed to the case of the instrument. Figure 2.1 shows a typical example.SPECIFICATIONSSingle Decade DBX UnitSINGLE DECADE UNITSORDERING INFORMATIONSingle-decade units are available withresistance as low as 1 m Ω per step toas high as 10 M Ω per step. These unitssatisfy many system applications re-quiring only a single decade whilemaintaining all the quality features ofthe DB series.Each decade is enclosed in an alumi-num case which can serve as a shield.It may be panel mounted and inte-grated with additional units to form potentiometer circuits or other con-figurations.Each unit consists of low-inductance resistors in series, with a high-perfor-mance solid-silver-alloy-contact switch.* For less exacting applications, more economical tolerances are available:- For 0.02% accuracy substitute DBQ in part number in lieu of DBX- For 0.05% accuracy substitute DBA in part number in lieu of DBX- For 0.1% accuracy substitute DBB in part number in lieu of DBX OPTIONS - RM Rack mountable case for standard 19" rack - K Kelvin type 4-terminal binding posts - RO Rear output binding postsChapter 3OPERATION3.2.2 Electrical Considerations In order to make proper use of the full performance capabilities of the DBX unit, especially if low resis-tance or low-resistance increments are important,care must be taken in connecting to the terminals of the decade box.In particular, in order to keep contact resistance to a minimum, the most substantial and secure connec-tion to the binding posts should be made. They ac-cept banana plugs, telephone tips, spade lugs, alli-gator clips, and bare wire. The largest or heaviest mating connection should be made, and, where ap-plicable, the binding posts should be securely tight-ened.These considerations may be relaxed whenever single milliohms are considered significant for the task being performed.3.2.3Four-Wire Kelvin Lead Connections Whenever possible, 4-wire Kelvin leads, the ideal connection, should be employed. Such a connec-tion minimizes the effects of contact resistance and approaches ideal performance.If the four terminals are available as clamps similar to alligator clips, they may be connected to the necks of the binding posts. If the four terminals are avail-able separately, the optimal connection is shown in Figure 3.1, where the current leads are introduced into the top of the binding posts, and the voltage leads at the necks.3.1 Initial Inspection and SetupThis instrument was carefully inspected before ship-ment. It should be in proper electrical and mechanical order upon receipt.An OPERATING GUIDE is attached to the case of the instrument to provide ready reference to speci-fications.3.2 Connection3.2.1General ConsiderationsThe DBX Series Decade unit provides three termi-nals labeled H (high), L (low), and G (ground). The H and L terminals are connected to the ends of the resistance being set; the G terminal is connected to the case. The G terminal may be used as a guard or shield terminal. It may also be connected (using a shorting link) to either terminal to allow two-termi-nal as opposed to three-terminal measurements.In order to make the most stable measurements,determine which is the more sensitive of the two user leads, i.e. the one going into a higher impedance.This lead should be connected to the more protected one of the two DBX terminals. That would either be the DBX terminal that is shorted to the case, or the LOW DBX terminal whenever neither is con-nected to the case.3.2.4 Thermal emf ConsiderationsThe highest-quality low-ernf components are used in the DBX Series. There nevertheless may be some minute thermal emf generated at the test leads where they contact the gold banana jacks.This emf will not reflect itself if an ac measurement instrument is employed. It will also be eliminated if a meter with so called “True Ohm” capability is used. Otherwise it may represent itself as a false compo-nent of the dc resistance measurement.3.3 Dial SettingWhenever the dials are used in positions 0-9, the resulting resistance is simply read directly. Both the decimal point and the steps are clearly marked on the panel.For additional flexibility and range, each decade pro-vides a “10” position setting. This “10” position on any one decade equals the “1” position on the next higher decade. It adds about 11% to the nominal total decade resistance.To determine the resistance obtained when one or more “10” settings are used, simply add “1” to the next higher decade. For example, a setting of3-6-10-0-10 Ω becomes:330000660001010000001010____________________________ TOT37010and a setting of 10-10-10-l0-10.10 Ωbecomes:10100000.01010000.0101000.010100.01010.0.10 1.0________________________________ TOT11111 1.0 3.4 Environmental ConditionsFor optimal accuracy, the decade box should be used in an environment of 23o C. It should be allowed to stabilize at that temperature after any significant tem-perature variation.Humidity should be maintained at laboratory condi-tions. This is especially important if high resistances are involved.Figure 3.1 Optimal 4-Wire Kelvin Lead ConnectionChapter 4 MAINTENANCE4.1Verification of Performance4.1.1Calibration IntervalThe DB Series instruments should be verified for performance at a calibration interval of twelve (12) months. This procedure may be carried out by the user if a calibration capability is available, by Omega, or by a certified calibration laboratory.If the user should choose to perform this procedure, then the considerations below should be observed.4.1.2General ConsiderationsIt is important, whenever testing the DBX Series Decade Units, to be very aware of the capabilities and limitations of the test instruments used. A resis-tance bridge may be employed, and there are di-rect-reading resistance meters or digital multimeters available that can verify the accuracy of these units, especially when used in conjunction with standards that can serve to confirm or improve the accuracy of the testing instrumentSuch test instruments must be significantly more ac-curate than ±(l00ppm+2 mΩ) for all applicable ranges, allowing for a band of uncertainty of the in-strument itself. A number of commercial bridges and meters exist that can perform this task; consult Omega.It is important to allow both the testing instrument and the DBX Substituter to stabilize for a number of hours at the nominal operating temperature of 23O C, and at nominal laboratory conditions of hu-midity. There should be no temperature gradients across the unit under test.Substantial Kelvin type 4-wire test terminals should be used to obtain accurate low-resistance readings. It is convenient, once the zero resistance has been determined, to subtract it from the remaining mea-surements. This can be automatically done in many instruments which have an offset subtraction capa-bility.4.1.3 Procedure1.Confirm the zero resistance of the unit.2.Determine the allowable upper and lowerlimits for each resistance setting of each decade following the specified accuracy. For theDBX series, these limits for any resistance“R” are [R±(0.0001 R + 2 mΩ)]. For the A,B, or Q series, see specifications.3.Confirm that the resistances fall within theselimits after subtraction of the zero resistance.4.If any resistances fall outside these limits, theassociated switch assembly may requirereplacement.4.2 SchematicRefer to Figure 4.1 for a schematic of the DB de-cade unit.8MAINTENANCEFigure 4.1.

General DescriptionIntroductionSCR Power Controllers are designed to regulate ac power to electrical heating processes, such as ovens, furnaces, heat sealers, etc. (Note: They are not designed to drive transformers, coils or other inductive-type loads.)The controller accepts an input signal, such as 4-20 mAdc from some signal conditioning device, e.g., a temperature controller. For most processes, the combination of a temperature controller and SCR power controller will provide very accurate, automatic temperature control. For manual operation, a manual control option with a remote potentiometer is available.General SpecificationsInputs:4-20 mAdc standard, or as ordered (seeserial number) minimum voltagerequirements 10 Vdc; all inputselectrically isolated via optical couplingSupply Voltage:110/120; 208/240; 440/480, 575/600Vac, or as ordered (Phase connectionnot critical on 3-phase units)Frequency:50/60 HzAmbient T emperature:30o to 122o F for listed power ratings Cooling:ConvectionProtection:Sub-cycle, current-limiting fuse; transientvoltage suppresionLoad Resistive, 1- or 3-phase - 3-wire Wye or Delta All specifications subject to change.1234567Figure 4a. Wiring scheme for Series 19Z.Figure 4b. Wiring scheme for Series 39Z.3.21 Zero-Cross Zero-cross mode power controllers may only be used with constant resistance heating elements, such as Nichrome. They are NOT intended for high-inrush loads. Depending on the type of element used, you can oversize the load controller.3.22 Phase-AnglePhase-Angle fired power controllers may be used with high-inrush loads if the "soft-start" option is installed.Figure 5a. Wiring scheme for Series 19P.Figure 5b. Wiring scheme for Series 39P .Section 4. OperationSeries19/394.1 Series 19Z/39ZThe Series 19Z and 39Z power controllers are designed to control ac power to electrical heating processes, such as ovens, furnaces, heat sealers, etc. (Note:They are NOT intended to drive transformer coupled or inductive loads.) The controllers consist of power semiconductors (SCRs), properly sized heat sinks, and trigger circuitry. These controllers accept a control signal (e.g., 4-20 mAdc) from a signal conditioning device, such as a temperature controller. The “Z” suffix designates the controller as operating in the Zero Cross, Zero Voltage Switched, or Zero Burst firing mode.A patented trigger circuit turns on the SCRs as close as possible to the point at which the ac sine wave crosses through zero. In effect, this turns the line voltage on and off in full cycles. With an input of 4-20 mA , the output will be FULL OFF below 4 mA and FULL ON at 20 mA. Proportioning action is obtained by varying the number of cycles ON to the number of cycles OFF. The resulting output power is integrated by the heaters to produce smoothly proportional heating that varies directly with the input signal.4.2 Series 19P/39PThe Series 19P and 39P power controllers are designed to control ac power to electrical heating processes, such as ovens, furnaces, heat sealers, etc. (Note: They are NOT designed to drive transformer-coupled loads.) The controllers consist of power semiconductors (SCRs), properly sized heat sinks, and trigger circuitry.These controllers accept a control signal (e.g., 4-20 mAdc) from a signal conditioning device, such as a temperature controller.The “P” Suffix designates the controller as operating in the Phase-Angle firing mode. Providing full proportional control, SCRs are turned ON during each 1/2 cycle at apoint (phase angle) of the ac sine wave, remaining ON for the rest of the1/2 cycle. By varying the phase angle setting, the amount of voltage reaching the load may be adjusted. The output voltage is proportional to the input signal. At 4 mA input, no voltage will be applied to the load; at 20 mA input, the output voltage will almost equal the line voltage.4.3 Voltage Limit Option (Phase-Angle Fired Units Only)The output voltage of the controller can be limited by adjusting the trimmer on the printed circuit board. Turning the adjustment clockwise will increase the out put voltage limit. This control will operate over a range of about 20% to full output. Ordinarily, this adjustment is used to protect heaters that cannot operate on full line voltage, or to limit the maximum heating of a process.4.4 Soft Start Option (Phase-Angle Fired Units Only)The soft start circuitry is used to slowly turn on the voltage from the controller to the load. It is used to protect the controller when it is operating into loads having high-current, turn-on characteristics, e.g., quartz or tungsten heaters. The output voltage will rise from zero to full output over various times, depending on the time option selected.The soft start circuit presents an initial high impedance which is inserted between the signal source and the controller. This impedance decreases in value with time. Soft start action can be seen as the input signal slowly changes from 4-20 mA when full output is required.4.8 TroubleshootingIf the power controller is not functioning properly, refer to these troubleshooting procedures.Symptom:No heat or reduced heat output.Possible Cause(s)Action1. Loss of line voltage.Check powersupply.2. Line fuse or controller fuse blown.Check heater forshort circuit andcorrect problem.3. No input signal.Check signalconditioner.4. Malfunction on trigger board.Consult factory.5. Open SCR Consult factory.Troubleshooting Flowchart Symptom: Heaters will not turn off.Section 6.

液位测量传感器

什么是液位测量传感器？
许多行业的过程控制中都使用液位传感器，它们分为两大类。
点液位测量传感器用于指示单个的离散液位高度，即指示预置的液位情况。
通常情况下，此类传感器的作用是上限报警，即指示过量填充情况，或者指示下限报警情况。
连续液位传感器更为复杂，可对整个系统进行液位监视。
它们可测量一定范围内的液位高度，而不是某一点的液位，因此会产生直接与容器中液位相关联的模拟输出。
为建立一个液位测量系统，此输出信号会传送到过程控制回路和可视指示器。
液位测量传感器选型
选择液位测量传感器之前需要考虑的问题包括：
∙测量液体还是固体？
∙应用环境的温度和压力范围是多少？
∙需要点液位测量还是连续测量？
∙需要多大的液位测量范围？
∙所测材料是否导电？
∙所测材料是否会覆盖或堆积在表面上？
∙液体表面是否会产生紊流、泡沫或蒸汽？
∙需要接触式还是非接触式液位测量？
∙需要哪种输出，模拟、继电器、数字显示还是其它？
设计类型
浮动开关
在此类点液位传感器中，磁浮子会随着液体表面移动，并会促发杆体中密封的“舌簧开关”。
这种简单且维护率低的设计不但可快速安装，最大程度地减小冲击、振动和压力，同时还适用于多种介质。
舌簧开关可以是单刀单掷(SPST)，也可以是单刀双掷(SPDT)。
非接触式超声波传感器
这类传感器包含一个模拟信号处理器、一个微处理器、多个二-十进制(BCD) 范围开关以及一个输出驱动电路。
脉冲和一个门极信号从微处理器发射出去后，经由模拟信号处理器传送到传感器，促使传感器向液体表面发送超声束。
接着，传感器检测液面反射的回波，将其送回微处理器，并生成表示传感器与液面水平之间距离的数字信息。
通过不断更新所接收的信号，微处理器计算出平均值，从而最终实现液位测定。
使用连续型传感器时，微处理器会将平均值转化为与液位成线性关系的4 到20 mA 模拟信号。
当液位回波未在8 秒内返回传感器时，系统的输出信号将降至4 mA 以下，指示液位过低或管道已空。
使用点传感器时，微处理器会将平均值与BCD 开关设置进行比较，并
对输出继电器上电来指示液位过高或液位过低。
如信号丢失超过8 秒，则继电器断电并恢
复原始状态。
此外，为减轻表面紊流现象，电子部分中加入了半秒延迟。
接触式超声波传感器
这些传感器中包含低能量超声波设备，可测量特定点的液位水平。
接触式超声波传感器由一
个现场安装的传感器和一个固态积分放大器组成，不含任何移动部件，也无需进行校准。
通
常情况下，它们都带有用于连接电源和外部控制设备的端子块。
超声波信号穿过传感器中半
英寸宽的缝隙，并会在其中包含液体时对继电器开关进行控制。
水平安装式传感器的检测平
面在缝隙的中部，竖直安装式传感器的检测平面在缝隙的顶部。
当液位降到这一水平以下时，
超声波信号将减弱并且最终会将继电器切换到之前的状态。
这些传感器用于在容器或管道中自动操作泵、电磁阀和上下限报警。
填充和排空罐体以及测
量液体量时需使用两个此类传感器。
此类传感器适用于大部分液体，它们不受覆盖层、液滴
粘连、泡沫和蒸汽影响。
但充气过多的液体和粘性过大并可塞满传感器缝隙的液体，则可能
导致故障。
电容式液位传感器
与超声波传感器一样，电容式传感器也可以进行点液位测量或连续液位测量。
它们利用探头
监测罐内的液位变化，并以电子方式将输出调整为电容值和电阻值，进而转换成模拟信号。
探头和容器壁相当于电容的两个极板，液体相当于电介质。
由于信号的发送只与液位变化有
关，所以探头上的物料堆积不会产生任何影响。
对于非导电液体容器，则需要两个探头或一
个外部导电片。
探头可分为刚性和柔性两种，通常都使用PTFE 绝缘的导线。
它使用不锈钢作为探头基础金
属，可为非导电液体、颗粒性液体或介电性质较低（介电常数小于4）的液体测量带来更高
的灵敏度。
当没有足够的间隙可以容纳刚性探头时或者在需要很长的探头长度的应用中，必
须使用柔性探头。
刚性探头的稳定性更高，特别是在存在紊流的系统中，因为探头的晃动会
导致信号起伏波动。
液位测量传感器类型
非接触式超声波液位传感器
由于具有多种电源和编程选项可供选择、能够进行RS-232 或RS-485 通讯、具有按钮校准和温度补偿信号，LVU40 系列传感器将连续非接触式液位测量的灵活性提升至一个新的高度。
它们结合了滤波机制，几乎可以消除外围障碍物的所有伪回波，可在0.3 到18.3 m（1 到60'）的整个范围内提供高精度测量。
通过与PLC（可编程控制器）或OMEGA CNi 系列控制器配合使用，可实现点液位测量。
雷达液位传感器
对于需要进行非接触式液位测量的应用，经济实惠的LVRD500 雷达变送器可谓是超声波传感器以外的理性之选。
它们非常适合于液体表面存在蒸汽、灰尘或泡沫等可对超声波测量造成阻碍的应用。
其雷达传感器使用微波脉冲技术，可对目标液体进行从天线顶端到缸体底部的跟踪。
这种先进的“回波标记式”信号处理方法可提供不受环境情况影响的可靠的连续脉冲波形。
同时还提供RS-232 和RS-485 型产品。
干料旋桨式液位开关
LVD-800 系列旋桨开关适用于多种颗粒状、丸状和粉状物质。
它采用已获得专利的磁性技术，可对料箱、料斗、料仓和料缸进行故障安全式监视。
具有自诊断功能的微处理器会持续监视轴和电机安装板的旋转，可对物料的存在情况以及机械或电气故障立即做出响应。
磁性传感机制避免了光学系统固有的误动作问题。
采用旋绕式机盖，不使用任何螺栓。
有2 个导管入口，并且大部分型号都有一个状态指示灯。
高温型号可承受399°C (750°F) 的温度。
电容式测量探头
LV3000/4000 系列探头可承受高温和高压并可耐受多种腐蚀物品，能够在恶劣的应用环境中提供可靠的连续液位测量。
它们适用于液体、糊状物和部分固体（导电和不导电均可），其中不含任何移动部件，而且安装简便。
在对输入电源进行整流和滤波、生成射频信号并计算电流变化后，电子线路将产生与过程液位成比例的 4 至20 mA 2 线制输出信号。
方便的零点和量程调整功能，使用户可以对各种变量进行设置，包括介质类型、容器尺寸、杆长度和安装位置。
如在可导电的容器壁附近使用不锈钢探头，则可选择PTFE 绝缘型号来防止短路。
