MagFlow

The "Magflow" series covers magnetic-inductive flow meters for filled and partially-filled systems as well as for open channels. They combine the well-known precision of the magnetic-inductive principle with simplest installation, high reliability and stability against contamination, corrosion and abrasion. By the characteristic of their functionality “Magflow” sensors achieve so far inaccessible accuracy compared systems appearing to be similar.

Function

Magnetic-inductive flow measurement is based on Faraday’s induction principle: the movement of a conductor in a magnetic field produces a tension in it. Magflow systems work according to the PDC-principle (Pulse Direct Current).

U_M = B * v * l

In a conductive measuring medium flowing through a pipe a tension is induced by the magnetic field perpendicular to the direction of flow. The amount of tension is proportional to the velocity of the measuring medium. On the sensor MAG-Flow TGR-EM there are two electrodes with which this tension is measured. A transmitter calculates the flow rate and the mass flow from this voltage.
