What are the two general types of electromagnetic flowmeter installation?

Electromagnetic flowmeter is a common flow measurement instrument that measures the flow of conductive liquid in pipelines based on the principle of electromagnetic induction. Due to its advantages of high precision, good stability, and wide application range, it is widely used in many fields such as chemical industry, petroleum, water treatment, and pharmaceuticals.

It works based on Faraday's law of electromagnetic induction. In the measuring tube, when the conductive liquid flows at a certain speed, it cuts the magnetic field lines and generates an induced electric potential. The magnitude of the induced potential is proportional to the flow rate of the liquid. By measuring the magnitude of the induced potential, the flow rate of the liquid can be determined.

The installation methods of electromagnetic flowmeters generally include flange connection and sanitary connection. During installation, ensure that the connection between the measuring tube and the flow meter is firm and leak-free. At the same time, in order to ensure normal operation, the following points should also be noted:

Before installation, impurities and foreign matter in the pipeline should be cleaned to ensure that there are no blockages and corrosion in the pipeline;

Select Proper installation location to avoid magnetic field interference and direct sunlight;

Connect the power and signal lines correctly according to the circuit diagram provided by the manufacturer;

Ensure good grounding to prevent static electricity and lightning from damaging the flow meter. Influence.

In terms of use and maintenance, you should regularly check whether the appearance of the electromagnetic flowmeter is normal and whether there is any mechanical damage or chemical corrosion. At the same time, the flow meter must be cleaned and maintained regularly, including cleaning the measuring tube and replacing worn parts. In addition, calibration should be performed regularly to ensure that the measurement accuracy of the flow meter meets the requirements.

Common problems and solutions:

Large deviation in measurement values: It may be caused by the pipeline not being cleaned, the flow meter not being installed correctly or improper selection. The pipes need to be cleaned and the flow meter reinstalled or replaced.

No display on the flow meter: It may be caused by power failure, circuit board damage, or poor signal line connection. The power supply needs to be checked, the circuit board replaced, or the signal cable reconnected.
