Piston flow switch F50 series

magneticfor liquidsfor gas

Magnetrol® flow switches are highly reliable flow control solutions utilized to sense the presence or absence of flow in horizontal pipelines. Disc-actuated Model F50 switches are in-line type used for sensing clean liquids in 2 inch or smaller line sizes. No calibration required Bronze or stainless steel construction Process pressures to 1150 psig (79 bar) Process temperatures to +750°F (+400°C) Actuation on increasing or decreasing flow In-line mounting Bodies for flow lines from ¾” to 2” OPTIONS Dry contact or hermetically sealed switches Actuation flow rates from 0.8 to 24.8 gpm The rate of flow through the valve body raises or lowers the disc. This in turn raises or lowers the magnetic sleeve, within its sealed non-magnetic barrier tube. On an increasing flow rate, the magnetic sleeve rises into the field of the permanent magnet, located outside the barrier tube, actuating the attached switch mechanism. When the flow rate drops, below the rate for which the flow disc is calibrated, a reversal of this action occurs.
