Electromagnetic flowmeter need external power supply?

Case introduction

1. What is an electromagnetic flowmeter

Electromagnetic flowmeter is an instrument used to measure the volume flow of liquid (or gas) in pipelines. It is widely used in industrial production, agricultural irrigation, urban water supply and other fields. Widely used. It works based on Faraday's law of electromagnetic induction and the theoretical principles of magnetohydrodynamics. The electromagnetic flowmeter consists of two parts: an electromagnetic coil and a sensor. When a conductive liquid passes through the flowmeter, the liquid will generate an electromotive force and affect the electromagnetic field. The sensor calculates the flow rate of the liquid by measuring this effect.

2. Electricity consumption of electromagnetic flowmeter

Electromagnetic flowmeter requires external power supply to drive the electromagnetic coil and sensor to work. When using an electromagnetic flowmeter, you need to connect the power cord, signal output line and sensor line so that the electromagnetic flowmeter can work normally.

3. Power supply requirements for electromagnetic flowmeters

Electromagnetic flowmeters generally require 220V power supply. Different types of electromagnetic flowmeters may have slightly different requirements for power supply voltage. Please refer to the specific situation. Corresponding product instructions. When connecting to an external power supply, attention should be paid to the stability of the power supply voltage and whether the wiring of the power cord is correct to avoid affecting the work of the electromagnetic flowmeter.

IV. Summary

Electromagnetic flowmeter is an important industrial flowmeter that can be widely used in liquid (or gas) flow measurement in different fields. Electromagnetic flowmeters require an external power supply to work properly. Different models of electromagnetic flowmeters may have slightly different requirements for power supply voltage. Please refer to the corresponding product manual for specific conditions. When using an electromagnetic flowmeter, correct wiring and basic stability of the power supply voltage must be ensured to ensure normal and stable operation of the electromagnetic flowmeter.
