Electromagnetic flowmeter installation precautions

Electromagnetic flowmeters (EMFs) are instruments that use Faraday's law of electromagnetic induction to measure the flow of conductive fluids based on the electromotive force generated by a conductive fluid by cutting a magnetic field line. Common faults of electromagnetic flowmeters include: no display of the instrument, inaccurate flow measurement, empty pipe alarm (FGP), system alarm (SYS), upper and lower limit alarm (FQH FQL).
Installation Precautions:

First, we choose the straight pipe section, no matter how big the pipe diameter is, we must ensure the straight pipe section requirements of the first ten and the last five, then the accuracy of the electromagnetic flowmeter can be ensured after use.

Second, as far as the environmental requirements of the installation are concerned, try to avoid direct sunlight, because the summer temperature is relatively high, and the excitation coil is easily damaged by the insulator.

Third, the installation position should be far away from the motor to prevent interference signals, and the meter head fluctuates greatly;

Fourth, the installation location is also very important. I will show you more clearly:

Fifth, we must ensure the full state of the liquid, some customers said, how to measure is not allowed? How is the numerical deviation very large? Look at your own pipeline is full of tubes, is there air inside?

Sixth, try to stay away from places with ammonia and acid mist corrosive air. If the on-site environmental conditions are not met, the user can make a request at the time of ordering, and the company will try to solve it.

Seventh, attention should be paid to the stability of the current when it is connected to electricity. There is also a distinction between 24V DC and 220V AC. The battery supply is not considered and will not be output.
