FLT flow switch

The FLT (flow/level/temperature) flow switch reliably monitors the flow and temperature of liquids, gases, slurries, lubricants, and other fluids to provide wet/dry detection and pump protection from damage due to sudden, unexpected reductions in flowrates. The FLT flow switch has a dual-alarm capability. Alarm 1 provides a pre-warning signal with the detection of low-flow situations between 0.01 and 3 ft/s, allowing the control system or operator to determine whether to keep the pump running or shut it down. When the feed line to the pump begins to run dry, Alarm 2 activates as an emergency signal to shut down the pump immediately to avoid over-heating and subsequent damage. The flow switch can be specified in either insertion or in-line styles for pipe or tube installation.
