Fluid Components International’s dual alarm FLT93 Series flow switch offers an early warning alert to the potential of dry operating conditions, cavitation and different pump points that can lead to emergency shutdowns and expensive maintenance.

FCI’s FLT93 Series flow switch reliably monitors the circulate and temperature of liquids, gases, and slurries. It is designed for pump wet/dry detection, the place sudden, surprising reductions in media flow charges can go away pumps weak to over-heating situations that shutdown process traces and require troubleshooting and fixing. The SIL2 rated instrument is intended for heavy-duty, potentially hazardous process trade environments and comes with a complete list of world safety approvals.
It has a no moving parts design and presents a strong scheme for pump protection with its dual alarm functionality. With Alarm 1, the swap detects a low flow scenario anyplace between 0.01 and 3 ft per second FPS (0.003–0.9 m per second MPS). This low move alarm is a pre-warning signal for the control system or operator who can then determine to maintain the pump working or to close it down.
If an Alarm 2 occurs as a result of the feed line to the pump is working dry, this would be an emergency signal to shut down the pump instantly because the bearings now see gasoline as an alternative of a liquid as a heat switch media. In such conditions, the temperature of the bearings may rise very fast. Using a move swap prevents everlasting injury to the pump’s bearings.
