三、差压式流量计基本理论1.节流装置工作原理差压式流量计是根据伯努力方程和流体连续性原理用差压法测量流量的，其节流装置工作原理如图1所示，在横截面H处：流体的平均流速是v1，密度是ρ1，横截面积是A1；在横截面L处：流体的平均流速是v2，密度是ρ2，横截面积是A2。

图1 差压流量计工作原理图根据流体流动连续性原理有如下关系式：v1·A1·ρ1=v2·A2·ρ 2 （1）如果流体是液体，可认为在收缩前、后其密度不变：ρ1＝ρ2＝ρ（2）根据瞬时流量的定义，即单位时间内流体流经管道或明渠某横截面的数量，所以液体的体积瞬时流量：2211A v A v q v ⋅=⋅= （3）根据伯努利方程（能量守恒定律），在水平管道上Z1＝Z2，则有如下关系式：2222222111v P v P ρρ+=+ （4）应用伯努利方程和流动连续性原理，在两个横截面上压力差则有如下关系式：)(2212221v v P P P -=-=∆ρ （5）将（3）代入（5）式，并整理，则得：22212])(1[2v A A P -=∆ρ（6）由于421D A ⋅=π， 422d A ⋅=π，定义直径比Dd =β，其中d 为工作状况下节流件的等效开孔直径，D 为管道直径，则得到：2224)1(2A q P v βρ-=∆ （7）这样可推导出以下的理论流量公式：1242411ρπβPd q v ∆⋅-= （8）又由于流量系数C 的定义是：C= 实际流量/理论流量，可得出节流式差压流量计普遍适用的测量体积流量的实际流量公式：ρπβεPd C q v ∆⋅-⋅=24124 （9）其中，ε为被测介质的可膨胀性系数：对于液体=1；对气体、蒸气等可压缩流体＜1 。

The unit contains a paddle wheel that has six ( 6) through holes to allow infrared light to pass through, a light-detecting circuit and a LCD-display electronic circuit.As fluid passes through the meter body, the paddle wheel spins. Each time the wheel rotates a DC square wave is output from the sensor. There are six ( 6)complete DC cycles induced for every revolution of the paddle wheel.The frequency of this signal is proportional to the velocity of the fluid in the conduit. The generated signal is then sent into the electronic circuit to be processed.The meter is factory programmed for the correct K-factor of the body size included with the meter.The flowmeter includes the following features: •Displays either the flow rate or the accumulated total flow.•Provides a pulse output signal that is proportional to the flow rate.•Provides an open collector alarm output signal. Active low at flow rates above the user programmed value.•Provides user selectable, factory preset calibration k-factors.•Provides a field calibration procedure for more precise measurement.•Front panel programming can be disabled by a circuit board jumper pin.Page 86.2 Control PanelEnter Button (right arrow) •Press and release -Toggle between Rate, Total, and Calibrate screens in the run mode.

Scroll through and Select options in the program mode.NOTE: To reset the circuit board: 1) Disconnect power 2) Apply power while pressing the two front panel buttons.6.3 Flow stream requirements•The flowmeter can measure fluid flow in either direction.•The meter must be mounted so that the paddle axle is in a horizontal position - up to 10° off the horizontal is acceptable.•The fluid must be capable of passing infra-red light.•The fluid must be free of debris. A 150 micron filter is recommended -especially when using the smallest body size (Sl), which has a 0.031"through hole.6.4 Run mode displayBody size/range 0 = Field calibrate 1 = 30-300 ml/min 2 = 100-1000 ml/min 3 = 200-2000 ml/min 4 = 300-3000 ml/min 5 = 500-5000 ml/min 6 = 700-7000 ml/min Function indicator R = Flow rate indicated T = Flow total indicated Field Calibration indicator Cal (steady)= active Cal (flashing) = calibrating none = factory cal. active Flow units indicator ML = Milliliters Alarm indicator SetP (steady)= active SetP (flashing) = alarm none = not programmed OZ= Ounces GAL= Gallons LIT= LitersDisplay ValueRate time base indicator Min = Rate per minute Hr= Rate per hour Day = Rate per day6.5 Run mode operation S 7ML FLOW RATE DISPLAY -Indicates rate of flow, S1 = body size/range ---� 0 #1, ML = units displayed in milliliters, MIN = time units in minutes, R R S1 T MinML 0= flow rate displayed.

The K-factor is defined as the number of pulses generated by the paddle per volume of fluid flow. Each of the six different body sizes have different operating flow ranges and different K-factors. The meter is factory programmed for the correct K-factor of the body size included with the meter.The meter's rate and total displays can be independently programmed to display units in milliliters (ML), ounces (OZ), gallons (GAL), or liters (LIT). Rate and total can be displayed in different units of measure. The factory programming is in milliliters (ML).The meter's rate display can be independently programmed to display time base units in minutes (Min), Hours (Hr), or Days (Day). The factory programming is in minutes (Min).For greater accuracy at a specific flow rate, the meter can be field calibrated. This procedure will automatically over-ride the factory K-factor with the number of pulses accumulated during the calibration procedure. The factory default settings can be re-selected at any time.7 .1 Field CalibrationAny body size/range can be field calibrated. Calibration will take into account your specific application's fluid properties, such as viscosity and flow rate, and increase the accuracy of the meter in your application.The Body Size/Range must be set for "SO" to enable the calibration mode.

LZK流量自动控制装置

一、概述LZK流量自动控制装置是机电一体化的高技术产品。

它是把流量计、流量阀及控制器三部分集于一体。

通过流量计设定的流量值，由控制器控制流量阀的开度，自动实现24小时流量控制。

此产品具有结构简单、操作方便、显示直观、控制精度高、交直流两用、手动控制或自动控制流量等特点。

二、特点1、流量计内部采用全硬质合金（碳化钨）结构轴承，从而提高了流量计的使用寿命。

2、钐钴永磁合金作为信号检测输出，信号强、磁稳定性好。

3、流量阀内部材料用耐磨钢经热处理精加工而成。

阀杆采用2Cr13材料，密封端硬度可达HRc45-50增强了耐冲击及耐磨性，提高阀的使用寿命。

三、技术参数1、介质温度：-40℃—120℃2、工作压力：1.6、2.5、4.0、6.4、16、25、35（MPa）3、瞬时流量稳定度：±0.01m3/h、±0. 1m3/h.4、防爆等级：EXd ⅡBT45、电源：AC220V、DC24V6、测量范围：1——2KHz7、输出信号：脉冲输出、4—20mA、RS485串行通讯接口。

目前油井注水是长庆油田提高产量的主要手段，但过去的油井注水多采用囵吞注水，由于各油层的地层吸水情况不同，这样会造成个别油层出现水淹，现在油田普遍采用分层注水法，以提高油井的产量。

中油测井生产测井中心根据油田公司“精细注水，强水拿油”确保上产稳产的战略方针，引进了先进的LZT-300流量自动测调仪系统，进行油田注水井的调配工作。

流量自动测调仪可以实时，快速，准确的完成注水井多层位的水量调节，属于油田应用中的新技术，也是思坦公司的新产品。

但在现场使用中存在一定的不足，测井成功率不高，此情况引起中心各级领导的重视，仪修相关人员全力配合厂方，专门为此成立仪修QC小组，通过对该测井系统的改进，大大提高了该仪器的下井成功率。

一、小组简介我们仪修ＱＣ小组成立于2012年3月．今年成员共有7名，其中工程师4名，技师1名，高级工2名，从人员组成可以看出，我们小组人员技术水平高，从事仪修工作时间长，经验丰富，有相当的设计，技术攻关能力。

Teledyne Hastings 300系列质量流量计说明书

INSTRUMENTSDESIGN FEATURESTeledyne Hastings Instruments (THI) prod-ucts represent over 55 years of experience in the design and manufacture of mass ﬂow products. The 300 Series is a culmination of this experience with patented technologies that make these the ﬁnest ﬂowmeters and controllers available today.The THI Mass Flow 300 Series products are designed to accurately measure mass ﬂow without corrections or compensations for gas pressure and temperature. They are accurate to better than ±1.0% of full scale. THI mass ﬂow instruments do not require any periodic maintenance under normal operating conditions with clean gases. No damage will occur from the use of moder-ate overpressures (~500 psi) or overﬂows. Instruments are normally calibrated with the appropriate standard calibration gas (air), then a gas conversion factor (GCF) is used to adjust the output for the intended gas. Special calibrations for other gases, such as oxygen, helium and argon, are available upon special order.The 300 Series products contain a number of features that set them apart from other available instruments: (1) They are inherently linear; no linearization circuitry is employed. Should recalibration in the ﬁeld be desired (a calibration standard is required), the cus-tomer needs to simply set the zero and span points. (2) The output signal is linear for very large overﬂows and will not come back on scale when a ﬂow an order of magnitude over the full scale ﬂow rate is measured. (3) The instrument incorporates a remov-able/replaceable sensor module. (4) The unit has very fast settling times.Models HFM-305,HFC-307FEATURES• Range — 1000-2500 slm (Air Equivalent); Higher Flows Available • ±1.0% of Full-Scale Accuracy 1• Rapid Settling Times: HFM-305 ≤ 0.4 seconds HFC-307 ≤ 2.0 seconds • Operating Pressures to 500 PSI • NIST Traceable Calibration APPLICATIONS• Gas Blending • Research• R&D and Process Flows •Pollution MonitoringHFM-305HFC-307Teledyne Hastings Instruments reserves the right to change or modify the design of its equipment without any obligation to provide notiﬁcation of change or intent to change.1See Product Manual for critical information on instrument accuracy and the use of GCFs (gas conversion factors).

干电池使用过期电压下降时，仪表（流量、温度计上的冒号：）将发生闪烁。

此时，请更换干电池。

b、认真确认软管是否已正确无误地连接在检测仪的输入、输出端。

检测仪可以并列接入高压侧，但流向若是接反则不能测量正确的流量。

c、液压回路动作前，应将加载阀反时针方向旋转打开。

d、加载阀可以用手简单地进行操作，在加压和卸压时，请缓慢地进行操作。

e、液压回路动作停止之前，要将加载阀打开，确认压力是否已降到零。

在进行多项压力测试时，每一次测试结束，也都应该将加载阀先打开，然后进行下一个项目的测试。

f、安全圆片是保护检测仪和液压机器的，测试时，请密切注意压力表的读数，使之不要超过回路的最高压力。
