Precautions for installation of submersible electromagnetic flowmeter

The sensor of the submersible electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. It is mainly composed of a measurement with insulation properties, a pair of electrodes installed through the wall of the measurement tube, and a pair of coils and iron cores used to generate a magnetic field. When the conductive fluid flows through the measuring tube of the submersible electromagnetic flow sensor, a voltage signal proportional to the fluid will be induced on the electrode. The signal is processed by the converter and outputs 4-20mA.DC current signal and 0-5kHz pulse signal. The submersible electromagnetic flow converter can also display instantaneous flow and cumulative flow, as well as upper and lower limit alarm Rs485 communication functions.

1. Try to avoid negative pressure in the measuring tube; 2. When measuring mixed-phase fluids, choose a place that will not cause phase separation; when measuring two-component liquids, avoid installing it downstream where the mixing is not uniform; when measuring chemical reaction pipes , should be installed downstream of the section where the reaction is fully completed; try to ensure that the front and rear straight pipe sections are not less than 5D and 2D respectively; 3. Avoid large motors, large transformers, etc. nearby to avoid electromagnetic field interference; 4. Choose a place with small vibration, especially for Integrated instrument; 5. A place where it is easy to ground the sensor alone; 6. Avoid direct sunlight as much as possible; avoid high-concentration corrosive gases in the surrounding environment as much as possible.
