In order to make the electromagnetic flowmeter work stably and reliably, the following requirements shall be paid attention to when selecting the installation site:
1. Try to avoid using ferromagnetic objects and equipment with strong magnetic field (such as large motor, large transformer, etc.), so as not to affect the magnetic field and flow signal of the sensor.

1. The shorter the signal cable is, the better;
2. The signal cable must be strictly separated from other power lines;

The signal generated by the electromagnetic transmitter is very weak, so it is an important factor to make good use of the electromagnetic flowmeter to prevent the impact of external electrical interference.

At present, the cable laying is divided into two types: nameless laying and concealed laying. Concealed laying refers to the unified consideration of electromagnetic flowmeter and other industrial control instruments in the design of the plant, and the steel pipes for laying cables are embedded in the cement floor and walls in advance.

Pay attention to the following points when wiring:
1. The wiring shall be carried out in strict accordance with the wiring diagram according to the principle of matching the transmitter with the converter.

The basic principle of hydropower is to use the water level drop to cooperate with the hydro generator to generate electricity, that is, to convert the potential energy of water into the mechanical energy of the hydro turbine, and then use the mechanical energy to drive the generator to obtain electricity.

1. Lightning protection of electromagnetic flowmeter
Whether as a sedimentation meter or an electromagnetic flowmeter for regional measurement, the electromagnetic flowmeter has become a relatively severe test in the relatively open suburbs, especially in the coverage of large thunderstorms in Guangdong.
