必需把握压的缩空气流量计使用注意事项流量计操作规程压缩空气是一种紧要的动力源，其具有震动大、气体带水、脉动流等特点，应用特别广。

无论是军事领域还是生活领域都可以找到压缩空气的身影。

因此认真了解把握压缩压缩空气是一种紧要的动力源，其具有震动大、气体带水、脉动流等特点，应用特别广。

无论是军事领域还是生活领域都可以找到压缩空气的身影。

因此认真了解把握压缩空气流量计使用注意事项是特别有必要的，也是必需的，从应用广度上来说，起码可以给使用单位节省不必要的经济损失。

（1）压缩空气流量计的测量范围较大，一般10：1，但测量下限受很多因素限制：Re＞10000是智能涡街流量计工作的最基本条件，除此以外，它还受旋涡能量的限制，介质流速较低，则旋涡的强度、旋转速度也低，难以引起传感元件产生响应信号，旋涡频率f也小，还会使信号处理发生困难。

测量上限则受传感器的频率响应（如磁敏式一般不超过400Hz）和电路的频率限制，因此设计时确定要对流速范围进行计算、核算，依据流体的流速进行选择。

使用现场环境条件多而杂，选型时除注意环境温度、湿度、气氛等条件外，还要考虑电磁干扰。

（2）压缩空气流量计简单显现故障的一大劲敌是振动。

因此在使用时注意避开机械振动，尤其是管道的横向振动（垂直于管道轴线又垂直旋涡发生体轴线的振动），这种影响在流量计结构设计上是无法抑制和除去的。

由于涡街信号对流场影响同样敏感，故直管段长度不能保证稳定涡街所必要的流动条件时，是不宜选用的。

即使是抗振性较强的电容式、超声波式，保证流体为充分进展的单向流，也是不可疏忽的。

（3）压缩空气流量计能有效的检测压缩空气的流量，有传统意义的智能涡街流量计的特点又有改进后的抗振动、无堵塞的优点，针对介质有脉动流的特点，建议客户在压缩机出口设置一只缓冲罐滤除脉动，而将流量计安装在缓冲后面，或者将流量计安装在阔别脉动源的地方，这样可利用工艺管道的气容同其管阻构成低通滤波器衰减脉动。

This avoids rounding errors generated internally during the conversion of the units and enables exact setting of the values. The setting at the fac-tory is Uni=CFH.If no button is pressed for 15 seconds during the setting procedure, the unit returns to the Run Mode with unchanged values.The unit can be electronically locked to prevent unwanted adjustment of the set parameters by pressing both push buttons until “LOC” is dis-played. With the unit in the locked state “LOC” is indicated briefly when you try to change parameter values. To unlock press both push buttons until “ULO” is displayed. Units are delivered from the factory in the unlocked state.OPERATING MODESRun Mode:Normal operating mode. Unit will perform its measurement and evalua-tion functions and provide output signals according to set parameters. Totalizer adds pulses of consumed quantity and displays them as cur-rent consumption value since last reset. Totalizer stores intermediate values every 10 minutes as well as elapsed time of set automatic reset. After a voltage dip this value is available as the current count of the total-izer (possible data loss can be maximum 10 minutes). Display indicates current measured values, yellow LED’s signal switching status of out-puts. Display unit can be temporarily changed (press “Set” button briefly, after 15 seconds unit returns to display unit set in menu point Uni). Display Mode:Indicates parameters and set parameter values. When “Mode/Enter”button is pushed briefly, unit passes to Display mode, which allows para-meter values to be read. Unit’s internal sensing, processing, and output functions continue as if in Run mode. Parameter names are scrolled with each press of “Mode/Enter” button. When “Set” button is pushed, corre-sponding parameter value is displayed for about 15 seconds. After another 15 seconds, unit returns to Run mode.Programming Mode:Setting parameter values: While viewing a parameter value pressing the “Set” button for more than 5 seconds causes unit to enter programming mode. Alter parameter by pressing “Set” button and confirm new value by pressing “Mode/Enter” button. Internal sensing, processing, and out-put functions continue as if in Run mode with original parameter values unless a new value is confirmed. Unit returns to Run mode when no but-ton has been pressed for 15 seconds.ADJUSTABLE PARAMETERS©Copyright 2009 Dwyer Instruments, Inc. Printed in U.S.A. 9/09 FR# RA-443445-00 Rev. 2Hysteresis Function:Keeps switching state of output stable if flow rate varies about presetvalue. With flow rate rising, output switches when switch-on point hasbeen reached (SPx). With flow rate falling, output does not switch backuntil switch-off point (rPx) has been reached. To adjust hysteresis: setswitch-on point, then set switch-off point at requested distance.Window Function:Enables monitoring of a defined acceptable range. When flow rate variesbetween switch-on point (SPx) and switch-off point (rPx), output isswitched (window function/NO) or not switched (window function/NC).Width of window can be set by means of the difference between SPx andrPx. SPx=upper value, rPx=lower value.Scaling measuring range (analog output):Analog start point (ASP) is the measured value at which the output sig-nal 4 mA is defined. Analog end point (AEP) is the measured value atwhich the output signal 20 mA is defined. Minimum distance betweenASP and AEP = 25% of final measuring range value. Output signalranges from 4 to 20 mA in set measuring range. Output is also indicatedby: flow rate above measuring range (output signal > 20 mA), or flow ratebelow measuring range (output signal between 3.6 and 4 mA).Fault IndicationOL: Detection range exceeded (flow rate > 120% of final value of mea-suring range)SC 1: Flashing - short circuit in switching output 1*SC 2: Flashing - short circuit in switching output 2*SC: Flashing - short circuit in both switching output*Err: Flashing - fault in measuring probe*Concerned output is switched off as long as short circuit continues.Faults are indicated even if display is deactivated.Figure 7Figure 5Figure 6Chart 3。

PV = nRT,where:P = pressure of the gasV = volume that the gas occupies n = number of molecules (i.e., mass)R = ideal gas constant T = temperature of the gas The ideal gas law defines the volume a certain mass of gas will occupy under specific conditions.For example, say a fixed mass of gas occupies a one liter container at 70°F under 1 atmosphere pressure.When the pressure of the system is increased (with the temperature held constant), the volume will decrease.If the temperature is increased, (with the volume held constant), the pressure will increase. The only constant variable is the mass of the gas; it does not change.Mass flow is the molecularmeasurement of the gas flowrate.This is usually measured in units of mass per unit of time, askilograms per hour. However, gas flow is usually measured in volume,such as liters per hour, but, since volume is dependent upon temperature and pressure, it isINTRODUCTIONThe continuing need for improved accuracy in flow measurement of mass related processes such as chemical reactions and thermal transfers has resulted in the development of electronic mass flowmeters. Thermal-type mass flowmeters operate with minor dependence on density, pressure,and fluid viscosity. This style of flowmeter utilises a heated sensing element and thermodynamic heat conduction principles to determine the true mass flow rate.Understanding Mass FlowTo understand the mass flow concept, it is essential to begin with the relationship between mass,temperature and pressure. Real gases roughly follow the ideal gas law, which states that the pressure,temperature and volume of a gas are all interrelated.ELECTRONIC MASS FLOWMETERSFlow Reference Sectiontherefore necessary to adoptstandard temperature and pressure conditions before one can define volumetric flow rate. Usually, these conditions are specified as 70°F and 1 atmosphere (14.7 psia) ing these standards, it is possible to take an exact mass flow andShown Smaller Than Actual SizeFMA-2100 Series (from £331)Figure 1: Insertion style mass flow sensor utilises RTD sensor to measure the flow rateD-3FMA-3300 series (from £267), see page D-14FMA-1700/FMA-1800series (from £289),see page D-15and 100 psig, flowing at 100 ACFM: Q s = 100 ACFM x(100 psig +14.7 psia)x(14.7 psia)(529.4 R)(459.4 + 100°F)OPERATING PRINCIPLE Electronic mass flowmeters and flow controllers employ thermodynamic principles to measure true mass flow rate without the need for temperature or pressure compensation. The following is a brief description of the two operating principles employed:heated tube and immersed probe.Heated TubeFMA-A2000, FMA-1700/1800,FMA-3300 Series FlowmetersIn these units, all or part of the gas flow passes through a precision-manufactured sensing tube (Fig. 2). Heat (Q) is applied to the gas flowing through the sensor tube via two externally wound resistance temperature detectors (T 1and T 2).The detectors have a dual function: toboth heat and sense the sensor-tubetemperature. When the molecules ofthe gas pass through the upstreamsensor winding (T 1) they carry away a certain amount of heat.reference it to more traditional measures without losing accuracy.For example, a 500 lb. per hour flow of nitrogen can be translated into standard cubic feet per minute (SCFM) units using the following relationship:•Q s = m/()s where:()s = density of the gasat standard conditions •m =mass flow rate Q s =standard mass flow rate(e.g., SCFM)In many applications, only the volumetric flow rate referenced to the actual pipe conditions is known.To convert actual cubic feet per minute (ACFM) to standardconditions (SCFM), the following relationship is used:Q s = Q a x (P a /P s ) x (T s /T a )where:P a = actual pressure P s = standard pressure T s = standard temperatureT a = actual temperature conditions Q a = actual mass flow rate(e.g., ACFM)For example, to determine thestandard flowrate of a gas at 100°FThis process is repeated at the downstream sensor winding (T 2)but less heat is transferred from the downstream sensor winding due to the flow’s having been preheated by the first sensor. The temperature differential (T 2-T 1)between the two sensors in aWheatstone bridge circuit ismeasured. Since the temperature difference between the two sensors is directly proportional to the mass flow of the gas (m), a highly accurate and repeatable flow measurement is obtained.Electronic mass flowmeters are not affected by pressure or temperature changes over the specified range ofthe unit.Also, heated tube mass flowmeters can accommodate virtually any clean gas. If the flow rangeremains the same, a correlation factor (K) is typically used torelate the calibration of nitrogen to the actual gas, This K factor is derived experimentally or from the gas density and coefficient of specific heat: K = ()C Pwhere:= gas density (g/liter) C P =coefficient of specific heat (cal/gram °C)D-4The flowrate of a reference gas (subscript “r”) and that of an actual gas (subscript “a”) are related as follows:Q a = (K r /K a )Q r=a a Where:Q = mass flow rate in SCCMNote that, in the above relationship,() and Cp are usually established under standard conditions.For example, to determine the flow rate of carbon dioxide (CO 2) when the flowmeter is calibrated in nitrogen at 100 SCCM, the conversion equation is Q CO 2=Q N 22CO 2=1.16 x 0.249x 100 = 77.0 SCCM 1.84 x 0.204A partial listing of correction factors for different gases is provided on page D-22. Consult Engineering for other factors.Flexibility, easy maintenance, and excellent low-flow sensitivity are the major benefits of heated tube mass flowmeters. The addition of an electromagnetically controlled automatic valve turns the meter into a mass flow controller, ideal for any application where mass (as opposed to volumetric) flowrate control is desired.The only requirement for this type flowmeter is that the fluid should be very clean (e.g., bottled gases),since the design makes these units very sensitive to dirt particles. For flows with any particulates present,the immersed probe style mass flowmeter should be considered.Immersion Probe StyleThese units consist of a thermal mass flow probe and integralelectronics for a linearised analog output (usually 0-5 Vdc, or 4-20 mA).The probe itself consists of two temperature-sensitive RTD(resistance temperature detector sensors). Both are constructed of reference grade platinum, coatedELECTRONIC MASS FLOWMETERSFlow Reference SectionFigure 3: Heated tube mass flow controllerxx D-5with glass. These sensors are large,rugged, insensitive to dirt, and easily cleaned. The first sensor constantly measures the ambient temperature of the gas flow and maintains the operational temperature differential of the second sensor. If the temperature of the flow varies, the first sensor detects and references it, providing a temperature-compensated basis for measurement.The second sensor is the flowdetection sensor, and is heated to a temperature 60°F higher than the first. As the gas flows past, a certain amount of heat is transferred from the heated sensor to the gas. The heat transfer rate is proportional to the mass velocity of the gas, or ()V. It is this principle of heattransfer from the sensor to the gas that is the key to the immersion-style probe. When the flow of gas passing over the flow sensorincreases, the sensor loses more heat to the gas. As it loses heat,more current is needed to maintain the 60°F temperature differentialbetween the two sensors. The twosensors operate together as part of a Wheatstone forced null bridge circuit (Fig. 4). The output signal of the sensor is the bridge voltage (or current) required to maintain the constant temperature differential,which is non-linearly proportional to the mass velocity ()V. The non-linear output of the bridge circuit is then linearised and converted to a standard analogue output signal by the integrally mounted electronics.Special Consideration for Insertion ProbesOMEGA ®FMA Series air velocity transducers measure air mass velocity. Mass velocity is velocity weighed by the gas density ()V.The fundamental units of (V) are Ib-m/ft 3x ft/min, or lb-m/ft 2/min, but,normally,(V) is referred to in terms of standard feet per minute (SFPM),where the standard reference conditions are 25°C and1 atmosphere pressure. To convert from SFPM to standard cubic feet per minute (SCFM), multiply the standard velocity in SFPM by the cross sectional pipe area. (For pipecross sectional area, see page Z-27). To convert from SCFM to actual cubic feet per minute, refer to the equation for converting from actual to standardised flowrate. FMA Series air velocity transducers measure the air mass velocity at the location of the flow sensor. Thepoint of measurement can be critical if flows are not uniform or flat. If a duct does not have a uniform flow,point measurements will not be the same throughout (see Fig. 5). Flow in a straight duct or pipe will usually be symmetrical and relatively uniform if the ratio of straight pipe length to pipe diameter is at least 10to 1 and the duct walls are relatively smooth. For example, 10 diameters in a 6" diameter pipe is 60". Tees,elbows, valves and other flowobstructions will cause irregularities in the flow until they have asufficient length of straight pipe to become more uniform.

一、概述LWQ型气体涡轮流量计是一种精确测量气体流量的速度式流量仪表，具有结构简单轻巧、计量精度高、重复性好、测量范围宽、安装维修方便等优点。

广泛应用于石油、化工、冶金、航空、科研等部门及工业领域中多种气体，如天然气、城市煤气、丙烷、丁烷、空气、氮气等气体的测量。

由于仪表精度高、重复性好，故适用于贸易计量及工业过程检测。

气体涡轮流量计在线测量时，其介质密度随温度和压力变化而变化，为精确测量，必须同时跟踪检测介质的温度和压力，并将不同工况下的体积流量换算成标准状态或约定状态下的体积流量。

由于该型流量计集温度、压力、流量传感器于一体，在线跟踪检测介质温度和压力并进行自动补偿、压缩因子修正运算，因此具有优良的低压和高压计量性能，特别适用于各种单相气体的测量，如天然气等气体的精确计量。
