Flowline Liquid Level Switches

The general purpose optic leak switch provides leak detection in and around secondary containment sumps, tanks and piping systems. 

Sensor may be located up to 1000’ from a Flowline relay controller.

Fail-safe leak sensor inverts “wet” to alert user for maintenance.

Requires only a small amount of liquid to detect the presence of a leak.

CSA approved for use in hazardous locations, the intrinsically safe ultrasonic level switch provides high or low liquid level detection of chemical, solvent or low viscosity petroleum based liquids. The submersible PP or PFA level switch sensor is universally mounted through the tank wall or inside the tank, and connected to a PLC or relay controller.

Compatible with Smart Trak and Switch-Pak installation fittings. Ideal for use as a high or low level switch in classified applications. Well suited for use in highly corrosive liquids.
