Description of the parameters specified before the installation of the electromagnetic flowmeter

Electromagnetic flowmeter is widely used in industrial sewage, domestic water, sewage, petroleum, chemical, steel and other industrial sectors. It can measure acid-alkaline corrosive media. Electromagnetic flowmeter mainly consists of two parts: sensor and converter. The principle of measurement Based on Faraday's law of electromagnetic induction, the main components of the sensor are measuring tube, electrode, excitation coil, iron core and yoke, and housing. The number of people who choose to use is because the electromagnetic flowmeter has accurate measurement and high stability. The correct selection and correct installation is the necessary condition for ensuring accurate measurement of the electromagnetic flowmeter.
     The electromagnetic flowmeter must be clear of the following parameters before installation:
1. Avoid strong vibration and strong corrosive places.
2. Keep away from strong magnetic field equipment.
3. The process does not allow the flow of the pipeline to be interrupted. When installing the flowmeter, a shut-off valve and a bypass line should be added.
4, the upstream of the flowmeter sensor should also have a certain straight pipe section, generally in 5D~10D.
5, can be installed horizontally, vertically and obliquely, but to ensure that the measuring tube is coaxial with the process pipe, and to ensure that the measuring tube is always filled with liquid.
6. The measuring tube, the outer casing, the shield wire of the lead wire, and the pipe at both ends of the sensor must be reliably grounded, and must not be shared with the grounding of other electrical equipment. This is a special installation requirement for the electromagnetic flowmeter.
