Saturated steam has the following characteristics ① to-one correspondence between the saturated steam temperature and pressure, there is only one independent variable therebetween. ② readily condense saturated steam, if heat loss during transmission, and lead to lower temperature and pressure. Strictly speaking, the saturated steam biphasic fluids containing more or less liquid mist or droplets, therefore, to describe the different states can not use the same gas state equation. Saturated steam steam flow measurement and metering system related to the density of the steam, and the density of the steam temperature of the steam with the pressure change. Therefore, Guangxi compressed air flow meter, steam flow measurement must be reasonable temperature and pressure compensation Guangxi compressed air flow meter super cheap, density correction, in order to improve the accuracy of flow measurement of steam, to reduce measurement error. Steam into saturated steam and superheated steam, steam due to the different nature, in the same pressure vapor density is different. Thus, in the measurement method of measuring steam flow used is different. Shall be measured according to the nature of steam, a reasonable choice of measurement equipment, instrumentation and compensation. First, the vortex flowmeter amplifier works vortex flowmeter amplifier is the actual user in the field can use only part of debugging. The role of the amplifier is the vortex signal generated by the fluid flow in the pipeline, Guangxi direct air flow meter, amplified by the circuit, after shaping filter output square wave signal. When the fluid in the tube through vortex flow sensors, piezoelectric crystal element produces an alternating electrical charge through the charge amplifier converts the charge amount proportional to the alternating voltage signal Guangxi wholesale air flow meter, and then sent to the voltage amplifier amplification, the voltage amplifier has a test point TP1, voltage amplification factor can be adjusted by the potentiometer W1. Low-pass filter to eliminate high frequency noise signals, so that the vortex frequency signal by the sensor measurement range, the filter output is a test point TP2. Schmitt trigger sine wave signal into a square wave signal, the output amplifier, the test after the trigger point for TP3.
