Fluid Components International’s dual alarm FLT93 Series circulate change supplies an early warning alert to the potential of dry operating situations, cavitation and other pump points that may lead to emergency shutdowns and costly maintenance.

FCI’s FLT93 Series flow switch reliably monitors the flow and temperature of liquids, gases, and slurries. It is designed for pump wet/dry detection, where sudden, surprising reductions in media flow charges can leave pumps vulnerable to over-heating conditions that shutdown process lines and require troubleshooting and fixing. The SIL2 rated instrument is intended for heavy-duty, probably hazardous process trade environments and comes with a comprehensive listing of world security approvals.
It has a no moving parts design and provides a strong scheme for pump safety with its twin alarm capability. With Alarm 1, the switch detects a low circulate situation wherever between 0.01 and three ft per second FPS (0.003–0.9 m per second MPS). This low circulate alarm is a pre-warning signal for the management system or operator who can then resolve to maintain the pump working or to close it down.
If an Alarm 2 happens as a outcome of the feed line to the pump is working dry, this may be an emergency signal to close down the pump immediately as a end result of the bearings now see fuel as a substitute of a liquid as a heat transfer media. In such conditions, the temperature of the bearings might rise very fast. Using a flow switch prevents permanent harm to the pump’s bearings.
