1.The paper introduces the corrosion prevention of the automatic instruments for thermopair,resistance thermometer, transmitter, flowmeter levelmeter in Chemical processes.
2.This article mainly designed one kind to use composition and so on PLC and flowmeter, PH idea, thermometer and liquidometer industrial sewage processing control systems.
本文计了一种利用PLC与流量计、PH计、温度计和液位计等的工业PH计 污水处理制系统。
3.Bench of closed circuit cooling tower that is composed of boiler ,exchanger, orifice flowmeter, water pump, micromanometer , heat indicator and so on is established.
建立了由锅炉、换热器、孔板流量计、水泵、微压计、温度计等仪器的封闭式冷却塔实验台。
4.The responsion functions of the eddy street flowmeter and the turbine control the separation of the gas-liquid,it's arithmetic was based on BP neural network improved PID control.
5.The structure of swirler in swirlmeter is changed.The corner dimension between inlet blades and basic shaft is changed into 45 from 60 and inlet blades into seven from six.
