FCI provides flow switch to guard from dry working

Fluid Components International’s dual alarm FLT93 Series flow swap supplies an early warning alert to the potential of dry running conditions, cavitation and other pump points that may lead to emergency shutdowns and expensive upkeep.

FCI’s FLT93 Series move swap reliably monitors the circulate and temperature of liquids, gases, and slurries. It is designed for pump wet/dry detection, the place sudden, sudden reductions in media move rates can leave pumps weak to over-heating conditions that shutdown process strains and require troubleshooting and fixing. The SIL2 rated instrument is intended for heavy-duty, probably hazardous course of business environments and comes with a complete list of global safety approvals.
It has a no transferring parts design and offers a sturdy scheme for pump safety with its dual alarm functionality. With Alarm 1, the swap detects a low circulate scenario anywhere 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 sign for the control system or operator who can then determine to keep the pump running or to close it down.
If an Alarm 2 occurs as a outcome of the feed line to the pump is operating dry, this may be an emergency sign to close down the pump instantly as a result of the bearings now see gas instead of a liquid as a heat transfer media. In such conditions, the temperature of the bearings could rise very quick. Using a move change prevents permanent damage to the pump’s bearings.
