Install these switches into an unthreaded hole at the top or bottom of your tank and secure with a nut from inside the tank.

Install these switches into a threaded connection in your tank wall from outside the tank.

Hang these free-floating switches in your tank for liquid-level monitoring that doesn't require installation through a tank wall.

For use in locations with flammable gases and combustible dust, this switch is UL listed and CSA certified for Class I, Divisions 1 and 2, Groups C and D; and Class II, Divisions 1 and 2, Groups E, F, and G.

Empty and fill your tank with a single device—these dual-level switches include two float switches that actuate at different levels. Mount through a threaded connection at the top of your tank.

Mount these switches through an unthreaded hole in your tank wall and secure with a nut from outside the tank.

For visual monitoring and easy access, these switches are housed in a clear acrylic reservoir that mounts to the outside of your tank.

These switches are CSA certified for hazardous locations.

Install these switches through a tank wall.

Use high-frequency sound waves to detect chemical level.

Mount these switches from outside the tank through a threaded connection at the top or bottom of your tank.

Install these switches into an unthreaded hole at the top or bottom of your tank and secure with a nut from inside the tank.

Install these switches into a threaded connection in your tank wall from outside the tank.

Mount these switches into a threaded connection at the top or bottom of your tank.

Mount these switches through an unthreaded hole in your tank wall and secure with a nut from inside the tank.

Measure the level of conductive liquids without drilling a hole in your tank—these switches mount to the outside of the tank and track the capacitance between them and the tank’s contents.

A polypropylene float makes these switches buoyant even in viscous liquids.

Install one of these relays to actuate equipment that has a higher current rating than your switch.

If the primary float fails, the backup float kicks in and an alarm sounds to indicate float malfunction.

Use these transmitters to measure the levels of corrosive, dirty, or sticky liquids without coming into contact with them.

Best for measuring liquid levels in applications where traditional mounting is difficult, these transmitters sit at the bottom of your tank.
