Electromagnetic Flow Meter

- An Inhouse Tested Product -

Model VPEMF Series

GENERAL
The VPEMF series electromagtic flow meter is a kind of flow
meter made by adopting Faraday law of electromagnetic
induction.

It’s used for measuring the volumetric flow rate of conductive

liquid and serous fluid in the closed pipe, and is applicable to
chemicals, power, mining and metallurgy, water supply and
drain, paper making, medicine, foods and so on.
FEATURES Remote
CE - LVD(2014/35/EU), EMC(2014/30/EU), Ex(2014/34/EU) Type
Pressure Equipment (2014/68/EU)
It’s not affected by the change of liquid density, viscosity,
temperature, pressure and conductivity.
Capable of measuring flows in both directions.
Compact Type
No maintenance is necessary because no driving parts,Lower
(Circular Converter)
requirements for straight pipe.
Adopts new excitation method, and features low power consumption,
stable zero point and high precision.
Adopts surface mounting technology (SMT) with the functions of
self-inspection and self-diagnosis.
Provides superb stability and accuracy for a long time,Maintains a
stable accuracy even at a site with a high level of noise and vibration.
