FCI’s FLT93 Series move swap reliably screens the circulate and temperature of liquids, gases, and slurries. It is designed for pump wet/dry detection, where sudden, surprising reductions in media move rates can leave pumps weak to over-heating conditions that shutdown process lines and require troubleshooting and fixing. The SIL2 rated instrument is meant for heavy-duty, potentially hazardous course of trade environments and comes with a comprehensive listing of worldwide security approvals.
It has a no transferring components design and provides a strong scheme for pump safety with its dual alarm functionality. With Alarm 1, the swap detects a low flow situation wherever between 0.01 and three ft per second FPS (0.003–0.9 m per second MPS). This low flow alarm is a pre-warning sign for the management system or operator who can then decide to keep the pump operating or to shut it down.
If an Alarm 2 occurs as a result of the feed line to the pump is working dry, this is able to be an emergency signal to shut down the pump instantly as a end result of the bearings now see gasoline as a substitute of a liquid as a warmth switch media. In such conditions, the temperature of the bearings might rise very fast. Using a circulate switch prevents everlasting harm to the pump’s bearings.
