TABLE OF CONTENTS Introduction (4)Specifications (6)Installation (7)Operational Start-Up (9)Troubleshooting (11)Flow Monitor Information (12)Repair Kit Information (13)Statement of Warranty (15)INTRODUCTIONFluid entering the meter passes through the inlet flow straightener which reduces its turbulent flow pattern and improves the fluid’s velocity profile. Fluid then passes through the turbine blades causing it to rotate at a speed proportional to the fluid velocity. As each blade passes through the magnetic field, created at the base of the pickoff transducer, AC voltage (pulse) is generated in the pick-up coil (see Figure 1). These impulses produce an output frequency proportional to the volumetric flow through the meter. The output frequency is used to represent flow rate and/or totalization of fluid passing through the turbine flow meter.FIGURE 1Schematic illustration of electric signalgenerated by rotor movementTURBINE METERThe FTB-1400 Series Turbine Flow Meter is designed to withstand the rigorous demands of the most remote flow measurement applications. The FTB-1400 Series Flow Meter maintains measurement accuracy and mechanical integrity in the corrosive and abrasive fluids commonly found in oil field waterflood project pipelines, in-situ mining operations, offshore facilities and plant locations. Simple to install and service, it can operate in any orientation (horizontal to vertical) as long as the“flow direction” arrow is aligned in the same direction as the actual line flow. For optimum performance, the flow meter should be installed with a minimum of 10 diameters upstream pipe length and 5 diameters downstream pipe length.FIGURE 2Typical cross-section of FTB-1411 throughFTB-1441 turbine flow meterSPECIFICATIONSMATERIALS of CONSTRUCTION: Body : 316 Stainless SteelRotor : CD4MCU Stainless SteelRotor Support and Bearings : 316 Stainless SteelRotor Shaft : Tungsten CarbideOPERATING LIMITATIONS:Temperature: -150 °F to +350 °F (-101 °C to +177 °C) The metershould not be subjected to temperatures above +350° F(177° C), or below -150° F (-101° C) or the freezingpoint of the metered liquid. High temperatures willdamage the magnetic pick-up, while lower temperatureswill limit the rotation of the rotor.Pressure : Maximum pressure ratings as follows:5,000 psi ─ all NPT meters up to 2"2,000 psi ─ 3" male NPT1,500 psi ─ 4" male NPT1,000 psi ─ 6" male NPT800 psi ─ all grooved end metersNote: Consult factory for pressure ratings for flanged meters. Accuracy:± 1.0% of reading Repeatability: ± 0.1%Calibration: Water (NIST Traceable Calibration) Corrosion: All FTB-1400 series turbine meters are constructed ofstainless steel and tungsten carbide. The operator mustensure that the operating fluid is compatible with thesematerials. Incompatible fluids can cause deterioration ofinternal components and cause a reduction in meteraccuracy.Pulsation andVibration: Severe pulsation and mechanical vibration will affectaccuracy and shorten the life of the meterFiltration: If small particles are present in the fluid, it is recommendedthat a strainer be installed upstream of the meter (see Table 1 WARNING: Pressure in excess of allowable rating may cause the housing to burst and cause serious personal injury.FLOW MONITOR:For a complete flow monitor package, Omega offers the FTB-1400 Series Flow Monitors (see Appendix B on page 12 for flow monitor information). These digital signal processing displays utilize the low-level frequency input from the FTB-1400 Series Turbine Meters to calculate flow rate and total. When ordered with an Omega FTB-1400 Series Turbine Meter, the included factory calibration will provide dependable and accurate flow information.REPAIR KIT:The FTB-1400 Series Turbine Meter Repair Kit is designed for easy field service of a damaged flow meter, rather than replacing the entire flow meter (see Appendix B on page 12 for repair kit information).Repair parts are constructed of stainless steel alloy and tungsten carbide and are factory calibrated to ensure accuracy throughout the entire flow range. Each kit is complete and includes the calibrated K-factor which is used to recalibrate the flow monitor or other electronics to provide accurate output data.INSTALLATION INSTRUCTIONSPrior to installation, the flow meter should be checked internally for foreign material and to ensure the turbine rotor spins freely. Fluid lines should also be checked and cleared of all debris.The flow meter must be installed with the flow arrow, etched on the exterior of the meter body, pointing in the direction of fluid flow. Though the meter is designed to function in any position it is recommended, where possible, to install horizontally with the magnetic pick-up facing upward.The liquid being measured should be free of any large particles that may obstruct rotation of the rotor. If particles are present, a mesh strainer should be installed upstream before operation of the flow meter. (See Table 1 on page 8.)TABLE 1 Strainer Mesh Installation DetailsThe preferred plumbing setup is one containing a by-pass line (Figure 3 on page 10) that allows meter inspection and repair without interrupting flow. If a by-pass line is not utilized, it is important that all control valves be located downstream of the flow meter (Figure 4 on page 10).This is true with any restriction in the flow line that may cause the liquid to flash. If necessary, air eliminators should be installed to ensure that the meter is not incorrectly measuring entrained air or gas.PARTNUMBER STRAINER MESH CLEARANCE FILTER SIZE FTB-1411, FTB-142160 × 60 .0092 260 Micron FTB-1412, FTB-142260 × 60 .0092 260 Micron FTB-1413, FTB-142360 × 60 .0092 260 Micron FTB-142460 × 60 .0092 260 Micron FTB-1425 60 × 60 .0092 260 MicronFTB-1431 20 × 20 .0340 .86mm FTB-1441 20 × 20 .0340 .86mmCAUTION: Damage can be caused by striking an empty meter with a high velocity flow stream.It is recommended that a minimum length, equal to ten (10) pipe diameters of straight pipe, be installed on the upstream side and five (5) diameters on the downstream side of the flow meter. Otherwise, meter accuracy may be affected. Piping should be the same size as the meter bore or threaded port size.Do not locate the flow meter or connection cable close to electric motors, transformers, sparking devices, high voltage lines, or place connecting cable in conduit with wires furnishing power for such devices. These devices can induce false signals in the flow meter coil or cable, causing the meter to read inaccurately.If problems arise with the flow meter and monitor, consult Appendix A (Troubleshooting Guide) on page 11. If further problems arise, consult the factory.If the internal components of the turbine flow meter are damaged beyond repair, turbine meter repair kits are available. Information pertaining to the turbine meter repair kits is referenced in Appendix B on page 12.OPERATIONAL START-UPThe following steps should be followed when installing and starting the meter.WARNING: Make sure that fluid flow has been shut off and pressure in the line released before attempting to install the meter in an existing system.1. After meter installation, close the isolation valves and open theby-pass valve. Flow liquid through the by-pass valve for sufficient time to eliminate any air or gas in the flow line.CAUTION: High velocity air or gas may damage the internal components of the meter.2. Open upstream isolating valve slowly to eliminate hydraulic shockwhile charging the meter with the liquid. Open the valve to full3. Open downstream isolating valve to permit meter to operate.4. Close the by-pass valve to a full closed position.5. Adjust the downstream valve to provide the required flow ratethrough the meter. Note: The downstream valve may be used as a control valve.FIGURE 3Meter installation utilizing a by-pass line(Shown with an FTB-1400 Series Flow Monitor)FIGURE 4Meter installation without utilizing a by-pass lineAPPENDIX ATROUBLESHOOTING GUIDE Trouble Possible Cause RemedyMeter indicates higher than actual flow rate -Cavitation-Debris on rotor support-Build up of foreign materialon meter bore-Gas in liquid-Increase back pressure-Clean meter-Clean meter-Install gas eliminatorahead of meterMeter indicates lower than actual flow rate -Debris on rotor-Worn bearing-Viscosity higher than calibrated-Clean meter and add filter-Clean meter and add filter-Recalibrate monitorErratic system indication, meter alone works well (remote monitor application only) Ground loop in shielding Ground shield one placeonly.

阿牛巴流量计的安装流量计技术指标阿牛巴流量计（均速管流量计）测量范围广泛，适用于大部分现场介质的测量。
是公认的节能型流量仪表。
今天就阿牛巴流量计普通的安装方式给大家详细总结下，对于生产型的企业大家都知道，阿牛巴流量计现场安装正常采用的是直接插入式（也就是焊接式）的连接方式。
1，安装首先的前提还是要确认现场直管段是否符合要求，具体要求可以参考相关手册或者咨询公司技术部门，然后根据现场流体方向确定流量计的安装方向。
2，在方向确定好之后，借助开孔器在管道上开孔（常规开孔大小为25mm）a，单面支撑；也就是说，在管道上根据阿牛巴传感器尺寸开一个孔，这样的安装方式适合现场口径小于600mm的管道，因为在小孔径的安装方式下，这样的安装方式足以保证传感器本身的稳定性，保证测量精度。
b；双面支撑；确定安装方向后，在管道上对称位置上开两个同样大小的孔，和上面单面支撑是相对的，也就是说，对于大口径的测量，为了保证传感器的稳定性，要采用双面固定的方式来安装阿牛巴流量计。
3，将阿牛巴流量计插入管道中，用点焊的方式将传感器固定在正确的位置上，但是要求探头部分在整个管道内径且与中心线在同一条中心线上4，最后将整个焊口全部焊接好，并对焊接部分做防锈处理。
而对于现场水泥管道，为了现场安装方便，公司会随阿牛巴流量计同时配备一块钢板，钢板与现场管道用螺栓对卯，然后阿牛巴流量计和钢板还是采取上述安装方式。
一、指针抖动：1．轻微指针抖动：一般由于介质波动引起。
可采用增加阻尼的方式来克服。
2．中度指针抖动：一般由于介质流动状态造成。
对于气体一般由于介质操作压力不稳造成。
可采用稳压或稳流装置来克服或加大浮子流量计气阻尼。
3．剧烈指针抖动：主要由于介质脉动，气压不稳或用户给出的气体操作状态的压力、温度、流量与浮子流量计实际的状态不符，有较大差异造成浮子流量计过量程。
二、指针停到某一位置不动主要原因是浮子流量计的浮子卡死一般由于金属管转子流量计使用时开启阀门过快，使得浮子飞快向上冲击止动器，造成止动器变形而将浮子卡死。

德尔塔巴流量计使用说明书北京肯普尔科技有限公司二OO五年二月目录一、序言 (3)二、基本原理与结构特点 (3)三、特点 (6)四、德尔塔巴基本安装方式及其所需直管段 (9)五、调试及运行 (14)一、序言在流量测量的过程中，由于被测介质的复杂，测量方法亦是多种多样，由此也就出现了各种基于不同测量原理的流量传感器或节流件。
按测量方法和结构来讲，可分为：差压式，式，涡街式，超声波式，热式，科里奥式；按安装方式可分为：插入式，封闭管道式，明渠式。
采用先进技术制造成形的德尔塔巴流量传感器，是根据差压式工作原理、插入式安装方法设计的流量传感器。
其完全符合空气动力学原理的子弹头形截面、高强度的无缝整体结构、具备本身抗堵能力的低压孔设计等技术均居世界领先地位。
二、基本原理与结构特点1．基本原理德尔塔巴与孔板等其它差压流量传感器一样都遵循伯努力方程：Q=K×C×DP其中：Q=管道内的体积流量K=流量系数C=流量常数DP=差压值可见：C为常数，要确定Q，必须确定K和DP如图所示：当流体流过传感Array器时，不仅在其前部产生一个高压分布区，高压分布的压力高于管道的静压。
而且流体流过传感器加速段时速度加快，在传感器后部产生一个低压分布区，低压分布区的压力低于管道的静压。
流体从传感器流过后在传感器后部出现部分真空，并且在传感器两侧后部产生漩涡。
均速流量传感器的截面形状、表面粗糙状况和低压取压孔的位置是决定传感器性能的关键因素。
低压信号的稳定和准确对均速传感器的精度和性能起着决定性的作用。
德尔塔巴能精确地检测以由流体的平均速度所产生的平均差压。
德尔塔巴流量传感器在高、低压区按科学计算有规律地排布着多对取压孔，使准确、稳定地检测平均流速成为现实。
2．结构特点Array a.科学的截面形状德尔塔巴子弹头截面形状所受到的牵引力最小，使得流体与传感器的分离点固定。
b.高强度结构德尔塔巴采用完整的无缝整体结构，避免了其它传感器的多片式结构导致的腔室间渗漏，保证了长期精度并有助于提高传感器的量程上限。
