Magnetic Flow Meters

Mag meters provide simple, proven, and reliable flow measurement
of electrically conductive liquids across many applications.

What Are Magnetic Flow Meters?

Magnetic flow meters, also known as mag meters or electromagnetic flow meters, are obstruction-less, uni-directional or bi-directional, volumetric flow meters that can be used in a variety of field applications. Mag meters are usually chosen for their ability to manage critical flow applications for electrically conductive liquids and fluids.

How Mag Meters Work

FARADAY'S LAW

FLOW MEASUREMENT

COMMON APPLICATIONS

Magnetic flow meters utilize the principle of Faraday’s Law of Electromagnetic Induction to measure the velocity of liquids. According to Faraday’s Law, if a conductive fluid passes through a magnetic field, it will produce an electric signal within the conductor that is directly proportional to the process fluid’s flow velocity in the magnetic field.

This principle is mathematically defined as E = k*B*D*V. The induced voltage (E) is directly proportional to the flow velocity (V) of the fluid traveling through the magnetic field (B).

Magnetic flow meters consist of a transmitter and a sensor that is placed inline to measure the induced voltage generated by the process fluid moving through a pipe. The transmitter converts the voltage generated by the sensor into a flow measurement which it then transmits to a control system.

Magnetic flow meters are an ideal choice for measuring electrically conductive liquids across nearly any industry, including:
