   孔板10bet程序解析以及组成的知识讲解:西安华恒仪表介绍:孔板10bet按国标规定进行设计、制造和检定的标准孔板无需实流标定,精度高、结构简单、制造成本低,但压力损失在所有标准节流装置中最大,不适用于要求压力损失小的情况,标准孔板广泛用于石油、化工、冶金、电力等行业。

 
  Procedure analysis and knowledge explanation of orifice flowmeter:Introduction of Xi'an Huaheng Instrument:Standard orifice flowmeter designed,manufactured and calibrated according to the national standard does not need real-flow calibration.It has high accuracy,simple structure and low manufacturing cost,but the pressure loss is the largest in all standard throttling devices,and it is not suitable for situations requiring low pressure loss.Standard orifice plate is widely used.Petroleum,chemical,metallurgical,electric power and other industries.
 
  孔板10bet主要由孔板节流装置,三阀组,差压官网,流量积算仪,温温度官网,压力官网组成
 
  Orifice flowmeter mainly consists of orifice throttle device,three valve groups,differential pressure transmitter,flow accumulator,temperature transmitter and pressure transmitter.
 
  孔板10bet可广泛应用于石油、化工、天然气、冶金、电力、制药等行业中,各种液体、气体、天燃气以及蒸汽的体积流量或质量流量的连续测量。但是许多人不知道孔板10bet的程序分析,今天我就和大家探讨一下孔板10bet的程序分析
 
  Orifice plate flowmeter can be widely used in petroleum,chemical industry,natural gas,metallurgy,electric power,pharmaceuticals and other industries,continuous measurement of volume flow or mass flow of various liquids,gases,natural gas and steam.But many people don't know the program analysis of orifice flowmeter.Today I will discuss with you the program analysis of orifice flowmeter.
 
  1.瞬时量
  温度量:必须转换成绝对摄氏温度;即+273.15;
  压力量:必须转换成绝对压力进行计算。即表压+大气压力;
  补偿计算根据计算公式,数据保存在PLC的寄存器内。同时在intouch画面上做监视。
 
  1.instantaneous quantity
  Temperature:must be converted to absolute Celsius temperature,i.e.+273.15;
  Pressure:It must be converted to absolute pressure for calculation.That is,surface pressure+atmospheric pressure;
  The compensation calculation is based on the calculation formula,and the data are stored in the register of the PLC.At the same time,monitor on the InTouch screen.
 
  2.累积量
  采用2秒中一个扫描上升沿触发进行累积,即将补偿流量值(Nm3/h)比上1800单位转换成每2S的流量值,孔板10bet进行累积求和,画面带复位清零功能。
 
  2.cumulants
  A scanning rising edge trigger in 2 seconds is used to accumulate,i.e.the compensated flow value(Nm3/h)is converted from 1800 units to the flow value of every 2S.The orifice flowmeter is used to accumulate and sum,and the picture has reset and zero-clearing function.
