流量计作为工业检测仪表,其品种已很繁多,但许多科研部门,生产单位急需的耐腐蚀,耐高压,耐高低温,小流量的检测计仍是一个空白。该院结合石油气裂解深冷分离工程的需要试制了一批远传流量计,经现场一年使用,证明性能良好。小型电远传流量计由流量发送器、信号转换器,显示仪表三单元组成。流量发送器按差动变压器原理工作,带铁芯的浮子随流量递增而上升,差动变压器次级即有相应的脉冲电压
Flowmeter as an industrial instrumentation, the variety has been very diverse, but many scientific research departments, production units much-needed corrosion resistance, high pressure, high temperature, low flow detector is still a blank. The hospital trial combined with LPG cryogenic separation project needs a trial of a number of far-flow meter, the use of the scene a year to prove good performance. Small electric remote meter by the flow transmitter, signal converter, display instrument three units. Flow transmitter according to the principle of differential transformer work, with the core of the float increases with the flow rate increases, the differential transformer secondary pulse voltage that has the appropriate
