Dwyer Series MFS Magnetic In-Line Inductive Flow Sensor

Dwyer Series MFS Magnetic In-Line Inductive Flow Sensor

Dwyer Series MFS electromagnetic sensors with electrical transmission output for indication of liquid flow rate. With no moving parts and accuracy in their readings of flow. Electromagnetic flow transmitters are for reversible gauging of the volume flow of conductive liquids in closed piping.

The Series MFS Magnetic Inductive Flow Sensor is a compact, low-cost alternative to paddle wheel sensors. Unlike sensors with moving parts, the MFS can be applied in applications dealing with contaminated media. This series provides a reliable measuring technique, an obstruction-free pipe cross-section, as well as a quick response time, making this series ideal for interference-free operation.

Any change in temperature, density, viscosity, concentration, or electrical conductivity of the liquid, does not affect the output signal of this Magnetic Inductive Flow Sensor. This, in addition to its long-life cycle, makes this series perfect for accurate reversible gauging of the volume flow of conductive liquids in closed piping.

The measuring pipe is in a magnetic field. If an electrically conductive medium with a certain flow passes through the pipe, it passes at a right-angle to the magnetic field, creating a voltage that is proportional to the average flow velocity and picked up by two electrodes within the MFS. A frequency output signal is obtained that is proportional to the flow (analog output option available).
