Electromagnetic flowmeter is now a mainstream flow meter in the market , Electromagnetic flowmeter can be divided into integrated electromagnetic flowmeter according to different needs and installation methods 、 Split electromagnetic flowmeter 、 Clamping electromagnetic flowmeter and plug-in electromagnetic flowmeter .

According to the working principle of flowmeter , Flowmeter can be divided into positive displacement flowmeter 、 Turbine flowmeter 、 Rotameter 、 swirl flowmeter 、 Throttling flowmeter 、 Electromagnetic flowmeter 、 Acoustic flowmeter 、 Mass flowmeter .

The full name of electromagnetic flowmeter is magnetoelectric intelligent flowmeter . Its advantage lies in the combination of the advantages of vortex flowmeter and electromagnetic flowmeter , It is an economical intelligent flow meter .

Gas flowmeter is an intelligent target flowmeter , It is based on the measurement principle of the original strain gage target flowmeter , A new capacitive force sensor is used as the measuring and sensitive transmission element , At the same time, it uses modern digital intelligent processing technology to develop a new flow measurement instrument .

At present, the mainstream steam flow measurement methods include throttling differential pressure flowmeter and vortex flowmeter , These two have their own advantages and disadvantages .

The correct use of rotameter is as follows ： First slowly open the valve upstream of the flowmeter , Until the valves are open , The flow can be adjusted downstream , When closing, first close the upstream valve , Downstream of shutdown .
