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

FCI’s FLT93 Series circulate switch reliably screens the move and temperature of liquids, gases, and slurries. It is designed for pump wet/dry detection, where sudden, sudden reductions in media circulate charges can depart pumps vulnerable to over-heating conditions that shutdown course of lines and require troubleshooting and fixing. The SIL2 rated instrument is intended for heavy-duty, potentially hazardous course of industry environments and comes with a comprehensive listing of worldwide safety approvals.
It has a no moving elements design and presents a robust scheme for pump safety with its twin alarm functionality. With Alarm 1, the swap detects a low flow state of affairs anyplace between zero.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 decide to maintain the pump working or to close it down.
If an Alarm 2 happens because the feed line to the pump is running dry, this would be an emergency signal to shut down the pump immediately as a outcome of the bearings now see fuel instead of a liquid as a heat transfer media. In such conditions, the temperature of the bearings might rise very quick. Using a flow switch prevents permanent harm to the pump’s bearings.
