MJK MagFlux® Flowmeters

MagFlux® Flowmeters are developed for measurements in all types of conductive liquids, including measurement of flow in drinking water, wastewater, sludge and process water. MagFlux Flowmeters are manufactured with carbon steel and stainless steel for flange or wafer connections and lining in hard or soft rubber and PTFE/PFA.

MagFlux® flowmeters

MagFlux® Flowmeters are designed with the latest microprocessor technology to ensure accurate measurements.

The Display is unique in its design in which it can be mounted in three different ways: locally on the sensor, remotely on a wall or mounted in a panel door. Furthermore, a single Display can operate up to 4 Flow Converters and Sensors.
MagFlux® Flowmeter has a very userfriendly menu structure with all instructions in clear text - no symbols or codes are used.

MagFlux® Flowmeters, Converters and Displays are supplied with a technically advanced enclosure made of glass reinforced polycarbonate giving maximum protection against harsh industrial environments.

MID Certified sensors from DN 25 to 400

Using a basic rule of the electro physics

MagFlux® electromagnetic flow meters are using one of the basic rules of the electro physics for measurement.

MagFlux® measures the velocity of the fluid through the flow sensor. Since the sensor is manufactured as a pipe, it is easy to calculate the flow when the dimension of the pipe is known

Q = (DN/2)2 x π x v , where

Q is the flow rate DN is the pipe inner diameter π is 3.14 V Is the velocity the fluid moves through the pipe
