Series MFS Magnetic Inductive Flow Sensor

No Moving Parts, Frequency and 4 to 20 mA Output, Maintenance-Free

The Series MFS Magnetic Inductive Flow Sensor is a compact, low cost alternative topaddle wheel sensors. Unlike sensors with moving parts, the MFS can be applied inapplications dealing with contaminated media. This series provides a reliable measuringtechnique, an obstruction free pipe cross-section, as well as a quick response time, makingthis series ideal for interference free operation. Any change in temperature, density,viscosity, concentration or electrical conductivity of the liquid, does not affect the outputsignal of this Magnetic Inductive Flow Sensor. This, in addition to its long-life cycle, makesthis series perfect for accurate reversible gauging of volume flow of conductive liquids inclosed piping.

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

Product Applications

Contaminated liquid flow monitoring
Flow of conductive liquids
Water & wastewater treatment
Industrial systems
Irrigation applications

Long life cycle with no moving parts to wear or break
Can be applied in applications dealing with contaminated media with no mechanicalcomponent in the flow
Obstruction free pipe cross-section yields low pressure drop
Unaffected by change in temperature, density, viscosity or concentration
