Varnika Powder Coated Metal Electric Digital Electromagnetic Flow Meter, Power : 24vdc Or 220vac

the varnika are flanged or insertion type electromagnetic flow meters used for pipe

1/2” to above in wastewater, chemical, industrial water or municipal application. micromag

has no moving parts and has round headed self cleaning type electrodes designed to

discourage fouling, magmeter performs well and requires minimum maintenance in

applications where debris or sand would impede propeller meters. there is no rotor to stop

turning or bearings to wear out. minimal straight pipe requirements allow micromag

meters to be used in piping configurations where there is little space between the meter and

an elbow. flow rate and total indications are standard on all models. flow measurement

units are customer-selected and factory set and can only be changed in the field by an

authorized varnika technologies

measuring principle:

the measurement is based on faraday’s law of electromagnetic induction according

to which, when a conductor is moved in a magnetic field, a voltage is induced in the

conductor. the voltage induced, in the case of an electromagnetic flow meter is:

u=k. b. v. d.

k=instrument constant

b=strength of magnetic field

v=average velocity

d=pipe diameter..

equalization and grounding

metal pipe installation: to equalize the electrical potential of the fluid, the micromag

meter, and the surrounding pipe secure the flange plates (factory installed on the

equalization lug) to both pipe flange at one of the bolt holes, as shown below. be sure the

lock washer fits between the pipe flange and the flange plate.
