Electromagnetic Flowmeter MX-LL-116-01

MX - LL - 116-01 series Electromagnetic flowmeter (Electromagnetic Flowmeters, EMF) : according to Faraday's law of Electromagnetic induction (Faraday's law of Electromagnetic induction: when the conductor in magnetic field cutting lines of magnetic force exercise, on both ends of a conductor will be induced a conductor and magnetic field direction and movement direction perpendicular induced electromotive force) tested flow meter.The advantages of electromagnetic flowmeter are that the pressure loss is very small and the measured flow range is large.The ratio of maximum flow rate to minimum flow rate is generally above 20:1, the applicable industrial pipe diameter range is wide, up to 3m, the output signal and measured flow rate are linear, the accuracy is high, can measure the conductivity ≥5 s/cm acid, alkali salt solution, water, sewage, corrosive liquid.

6.Selection instructions - Earthing ring:1. The grounding ring is used to ground the measured medium and improve the stability of electromagnetic flowmeter measurement.However, the grounding ring needs to be in contact with the measured medium, and there is the possibility of corrosion and wear. After a period of use, it needs to be replaced.2.Shanghai Meixu measurement and control electromagnetic flowmeter generally USES grounding electrode instead of grounding ring, which has achieved good grounding effect and increased the convenience and reliability of use.3. Some small diameter electromagnetic flowmeters only have 2 electrodes, so users need to equip with a double ground ring.

The earthing ring should be installed in the exact pipe position so as not to affect the flow field of the measured medium
The measurement accuracy of electromagnetic flow depends on the grounding effect of the sensor
