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

FCI’s FLT93 Series flow swap reliably screens the circulate and temperature of liquids, gases, and slurries. It is designed for pump wet/dry detection, where sudden, sudden reductions in media move rates can go away pumps susceptible to over-heating conditions that shutdown course of lines and require troubleshooting and fixing. The SIL2 rated instrument is intended for heavy-duty, probably hazardous course of industry environments and comes with a complete record of world safety approvals.
It has a no transferring parts design and presents a strong scheme for pump protection with its twin alarm functionality. With pressure gauge , the switch detects a low circulate scenario anyplace between 0.01 and 3 ft per second FPS (0.003–0.9 m per second MPS). This low circulate alarm is a pre-warning sign for the management system or operator who can then determine to maintain the pump working or to close it down.
If an Alarm 2 occurs because the feed line to the pump is operating dry, this may be an emergency signal to shut down the pump instantly because the bearings now see gas as a substitute of a liquid as a warmth transfer media. In such conditions, the temperature of the bearings may rise very fast. Using a flow switch prevents permanent injury to the pump’s bearings.
