第一章1.0 简介为了计算气体的总能量、体积量和瞬时流量而设计了2000型气体测量修正仪。

在计算时，使用了涡轮流量计的脉冲输出（或者超声流量计的输出）以及温度变送器和测量管线压力的压力变送器的输出。

如果需要的话，该修正仪可以使用预先设定的或者实时输入的气体相对密度（即比重）、气体的组分数据和热值。

为了计算气体流量，采用了以下几种计算气体压缩因子（Z因子）的方法，如：AGA 8,ISO12213和AGA 3 ，NX19。

对于一些特定应用场所，也可以采用固定的Z因子。

修正仪能够对所有实时输入的信号进行上、下限报警，而在报警的状态下，可以使用默认值来取代处于报警状态的参数以进行流量计算。

对于发生和取消报警的时间都有指示，同时也提供报警的输出信号。

本修正仪的特点是它采用数字通讯，温度与压力变送器都采用HART协议进行通讯，从而消除了校准修正仪及调节电位器的必要。

这一特点也限制了由于环境温度所带来的流量测量误差，只有温度和压力变送器的温度系数会产生误差。

修正仪有两个RS232/RS485串行数据通讯接口，为了能和系统的其他器件通讯，通讯协议为MODBUS ASCII，还有一个ASCII的串行通讯协议可以和大多数打印机通讯。

为了使操作数据和流量测量结果具有最大的安全性同时保持辅助功能的灵活性，修正仪具有编辑功能：既可以更改已选定的数据同时又利用临界数据保持其安全性。

为确保所有的信号都在设计要求的范围内，对所有的输入输出信号都进行测试。

当报警发生和清除时，每一个报警显示都记录发生和清除的时间。

如有报警发生时，可以选定将报警期间的累计总量单独累计并单独显示。

第二章2000型气体测量修正仪，它包括一个19英寸标准尺寸的安装支架（但只有1/2 宽），还包括和母板连接的许多接插件式的印刷电路板。

修正仪的前面板包括一个液晶显示屏，键盘，操作按钮和LED显示器。

液晶显示屏（LCD）是图形点阵式的，用于显示输入数据和流量信息。

1. PRINCIPLE OF OPERATIONA tapered glass flow tube, and a metallic or PTFE float inside it, constitute the heart of model FLD variable area flow meter.Flow meters are installed vertically in lines carrying gases or liquids to be monitored.Fluids enter through the smaller opening at the bottom, and exit through the upper end. Upward pressure causes the float to rise. Flow takes place through the circular area between the float and the inside surface of the flow tube. As the float rises,the flow area increases, due to the tapered bore of the flow tube.Dynamic equilibrium results when the buoyantforce of the float and the upward force, due to fluid pressure, balance the weight of the float.The vertical position of the float at equilibrium corresponds exclusively to one particular flow rate. This flow rate is obtained by determining the height of the float with the aid of the scale on the flow tube.2. MATERIALS OF CONSTRUCTIONFlow Tubes: Heavy walled precision formed borosilicate glassTube Shields:PolycarbonateFloats: 316 stainless steel, or PTFE Wetted Parts: Brass, type 316 stainless steelor PTFE.Seals: ®for brass and stainlessmodels, PTFE for PTFE models. Scales: Direct readingMeters are designed with unique “revolving” scales of dual air-water direct reading graduations showing SCFM and SLPM for AIR, as well as GPM and LPM for WATER. Knurled scale endings accessible at the lower back portion of the meters enable rotation of the scale.3. METER SPECIFICATIONSStandard Accuracy:± 5% FS Repeatability:± 0.25%Max. Operating Pressure: 150 psig/10bars (brass or stainless models); or 100 psig/6.7 bars (PTFE models).Max. Operating Temperature: 250ºF/121ºC (brass or stainless models); or 150 ºF/65ºC (PTFE models. Fittings: 3/8”-18” NPT FemaleAll meters are factory tested for leakage prior to shipping. For hazardous fluids the flow meter must be re-tested at the time of installation in the system, prior to usage. It is also important that a leak integrity test is performed periodically to maintain safe operating conditions. Flow meters must be protected from breakage due to external conditions such as objects bumping into or hitting the instrument, extreme vibrations, or attack by corrosive materials. It is the responsibility of the customer to acquaint the operator(s) of this flow meter with all appropriate safety information.4. INSTALLATION AND OPERATION4.1 Receipt of EquipmentInspect instrument for possible visible damage resulting from shipping. Notify UPS or othercarrier as well as Omega.4.2 InstallationFlow meters must always be installed in vertical position; any significant deviation from vertical will affect readings.Valves must be closed prior to installation and opened gradually after all connections are carefully inspected. A leak test is highly recommended especially when hazardous fluids are involved.CAUTION:Excessive tightening of valves may damage the orifice.It is important that all lines to be connected to the flow meter are purgedof any dust or otherVitonresidual contamination prior to installing the meter. In some applications a filter should be installed at the inlet of the flow meter.4.3 OperationFlow meters are designed to be operated at pressures and temperatures not exceeding recommended maximum values (see above).Close valve (if applicable) before initial use, then gradually pressurize the system.Slowly open the valve until the float is at the desired flow rate. Each scale indicates the “reading line” on the float where the flow rate should be read.5. FLOW TUBE INSTALLATION/REMOVALƽ Do not remove the flow tube from the flowmeter. Please contact Customer Service.6. MAINTENANCEƽ Do not remove the flow tube from the flowmeter. Please contact Customer Service.Under normal operating conditions no special maintenance is required. Dirt or contamination may create problems within the flow tube bycausing a restriction in the flow passage. Such conditions can be diagnosed by examining the flow tube.The most obvious indication of obstructions is the float being stuck in the flow tube. If the existence of contamination is determined the condition may be rectified in a number of ways. The easiest being (if possible), to disconnect the inlet and the outlet of the flow meter and purge the instrument by using a clean and dry stream of gas.Action of the float within the bore of the flow tube very often facilitates particles or impediments to be dislodged through the outlet of the flow meter .。

If this occurs, change the battery immediately.Disconnect the battery. Press and hold the Read key for 15 sec-onds. Release the Read key. Press and hold the Check key for 15 seconds. Release the Check key. Connect a fresh battery to the lead wire in a single action, making sure to align the poles prop-erly and without interrupting contact. If the display remainsfrozen, repeat the procedure. If this procedure does not solve the problem, refer to the Service for Y our Meter section.456A few meter readings in a limited number of specific areas of a large mass can not be projected to indicate an average moisture content of an entire bale.The readings can be very helpful in providing an indication of the overall moisture con-dition inside the bale and to detect areas of excessive mois-ture.Meter readings may be used as an arbitrary guideline in determining whether or not to accept or reject the material. Since checking the moisture condition of bales is performed when buying and selling, the specific value of the meter read-ings remains an element to be agreed upon between buyer and seller. Such an agreement should consider not only a spe-cific “range” of readings, but the number and location of where they are taken.The following ranges can be used as a guideline and may help to interpret the readings:h Readings of 5%–10%, with EMC to 60% RH are usuallyconsidered “dry”.h Readings from 11%–20% with EMC to 95% are usuallyconsidered “acceptable” but should be taken with somereservation.h Readings of 20%-40% are considered “wet” and unac-ceptable.CARE OF YOUR METERTo keep your meter in good working order:h Store your meter in a clean, dry place. The protectivecarrying case provided is an ideal storage place whenthe meter is not in use.h Change the 9-Volt battery as needed. Continued use with alow battery may cause the meter to go out of calibration.h Change contact pins as needed. Keep pin retainers handtightened.h Clean the meter, contact pins, and probes with anybiodegradable cleaner. Use the cleaner sparingly and onexternal parts only. Keep the cleaner out of the external con-nector. DO NOT IMMERSE THE METER OR ANY ELEC-TRODE IN WATER.h Remove the battery if the meter will not be used for onemonth or longer.8NOTESNOTESNOTES51 Indian Lane EastTowaco, NJ 07082(877)-DELMHORST ******************©2006, Delmhorst Instrument Co.510INS-0013REV. 9/14W H E N A C C U R A C Y I S T H E P O I N T .®For over 65 years Delmhorst Instrument has been the leading manufacturer of high quality, US-made moisture meters and ther-mo-hygrometers.
