New flow sensor announced by Dwyer Instruments

Indiana-based Dwyer Instruments, a specialist manufacturer in the controls and instrumentation industry, has announced the addition of a new flow sensor to its product range.

The Series MFS2 Magnetic Inductive Flow Sensor is a compact, low cost, PVDF electromagnetic flowmeter. Unlike sensors with moving parts, the MFS2 can be used in applications dealing with contaminated media in ½", ¾", 1" or 1-1/4" diameter pipes. This series provides a reliable measuring technique with a ±1% accuracy, 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, does not affect the output signal of the magnetic inductive flow sensor. This, in addition to its long life cycle, makes the series ideal for accurate reversible gauging of volume flow of conductive liquids in closed piping. The unit is available for flow ranges from 0.02 to 66 gpm (0.25 to 250 lpm).

The flow sensor operates by creating a magnetic field in its measuring pipe. When an electrically conductive medium passes through the pipe a voltage is created that is proportional to the average flow velocity. This velocity is picked up by two electrodes within the MFS2 and a frequency output signal is obtained that is proportional to the flow.
