Electromagnetic flowmeter total flow display does not move

　　First, the electromagnetic flow meter principle of operation

　　Electromagnetic flowmeter is a use of Faraday electromagnetic induction principle of flow measurement instruments, applicable to a variety of conductive media (such as water, liquids, mineral fluids, etc.) flow measurement. Electromagnetic flowmeter measurement principle is the fluid in the magnetic field in motion, by the induction electrode cut, the formation of induced potential, the size of which is directly proportional to the conductivity and flow through the conductor of the volume flow. Figure 1 for the electromagnetic flow meter measurement principle.

　　Second, the electromagnetic flowmeter total flow display does not move causes

　　Electromagnetic flowmeter total flow does not move may have a variety of reasons, before checking, you should first check whether the wiring is correct, whether the power supply is normal, whether there is a power failure, disconnection and other issues. The following are the common reasons:

　　1. Improper choice of installation location

　　Electromagnetic flowmeter installation location selection is very important, in the installation should pay attention to the flow direction of the flowmeter, the installation of improper location selection leads to the flowmeter is in a non-normal flow state, which leads to the total flowmeter does not move.

　　2. Poor line contact

　　Electromagnetic flowmeter line contact failure may be one of the causes of the total flow does not move, you can observe whether the power indicator is normally lit, observe the touch screen can be operated correctly and other ways to investigate.

　　3. Flow meter internal failure

　　Electromagnetic flowmeter internal failure may be one of the reasons that lead to the total flow does not move, such as sensor failure, signal module failure, motherboard failure, etc., need to check the fault repair or replacement parts.

　　Third, the total flow of electromagnetic flowmeter does not move to solve the problem

　　In view of the above problems, this article provides a solution:

　　1. check whether the installation position is correct

　　According to the instructions for the use of electromagnetic flowmeter installation operation, to ensure that the flowmeter normal flow, to avoid the flowmeter is in a non-normal flow state, resulting in the total flow does not move.

　　2. Confirm that the line contact is good

　　Check whether the electromagnetic flowmeter line is in good contact, whether it is short-circuited or disconnected, and the part with poor contact should be dealt with in time to ensure that the electromagnetic flowmeter works properly.

　　3. Repair or replacement parts

　　If the internal failure of the electromagnetic flowmeter is serious, it is necessary to repair or replace the accessories to ensure the normal operation of the electromagnetic flowmeter.

　　Fourth, the conclusion

　　This paper introduces the electromagnetic flowmeter total flow does not move the reasons and solutions, electromagnetic flowmeter in use need to pay attention to the installation location, line contact good condition, etc., if there is an abnormal situation, should be timely repair or replacement parts, to ensure that the electromagnetic flowmeter normal operation.
