Full Bore Electromagnetic Flow Meter IP68 Mag Flow Water Meter
 

1.Fast Brief introduction

MTF electromagnetic flow meter, composed of sensor and
converter, works based on Faraday’s law of electromagnetic
induction. It is used to measure electrical conductivity of liquid
or solid.

3.Tips of choosing Ground Ring

1). If the pipe connecting to the meter is insulated,the ground ring is needed,

generally metallic or non-metallic grounding rings or grounding electrode

(non-metallic) material is available to adapt to the corrosion of the measured

material.

2). If the measured medium is abrasive, ground ring with neck should be used

to protect lining material of two sides and to prolong its life.

In order to make the reliable operation of the instrument, and to improve

measurement accuracy, free from outside interference of Send potential,the

sensor should have separate ground wire, and the ground ring of both sides

of the sensors should be fitted when the ground resistance, in the pipe

connecting to the sensor or non-metallic pipe, is less than 10Ω.

4.Selection of Protection Level

IP65 means water-jet type; it allows the taps spray from all the

directions of the instrument. the pressure is 30kPa(0.3bar),

the output of the water is 12.5l/m,and the taps is 3 meters

far from the instruments.

IP67 means anti-immersion type, it can be submerged in the

water in a short time, when testing, the highest point in the

experiment should be at least 15cm underwater and last for at

least 30 minutes.

IP68 means Submersible-type, it can work in the water for
long-term, Its maximum depth in the water should be consulted

by the manufacturer and the user.

Conculsion:The choice of protection should be selected in
accordance with the above requirements, as well as the actual
instrument conditions. If the meter works under the ground and
always submerged by the water, IP68 should be selected, If
the instrument is installed above ground, IP65 is optional
