气体流量测量的温度压力补正,在工艺流程和能源管理上是急待解决的问题。西安仪表厂生产的Ⅰ系列乘除器是用作温压补正较理想的仪表,它允许压力、温度变送器的测量范围不一定从零开始进行合理选择,并通过乘除器的内部偏置,把输入的温度、压力测量值变成绝对温度、绝对压力。运算精度高、使用方便。本文从推导气体流量补正公式开始,将补正公式转换成乘除器的标准运算公式,指出公
Gas pressure measurement of temperature and pressure correction, in the process and energy management is an urgent problem to be solved. Xi’an Instrument Factory production of Series I multiplier is used as a warm pressure correction ideal instrument, which allows pressure, temperature transmitter measuring range is not necessarily a reasonable choice from scratch and through the multiplier and divider, the internal bias, the Enter the temperature, pressure measurement into absolute temperature, absolute pressure. High precision operation, easy to use. This article starts with the derivation of gas flow correction formula, and converts the correction formula into the standard operation formula of multiplicator and divider,
