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

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

Detect water level with infrared light to avoid false switch activation caused by vibration in your tank.

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

Mount these switches from outside the tank through a threaded connection.

Use the included bracket to mount these switches to the inside of your tank.

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.

Mount this switch through the top of your tank.

This switch mounts to the outside of your tank and detects chemical level through plastic tank walls by measuring the capacitance between the switch and tank contents; it cannot be used with metal tanks.

Detect chemical level with infrared light to avoid false switch activation caused by vibration in 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.

Designed for use in areas where flammable substances are present, these switches are CSA certified for hazardous locations.

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

Cut the probes on these switches to fit the size of your 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.

Detect when oil rises on water, foam forms on beer, and tanks empty, triggering pumps and valves in food and sanitary lines. These switches are 3-A and European Hygienic Engineering and Design Group (EHEDG) certified since they’re easy to keep clean.

Activate your pump in dirty water that contains sludge and sewage.

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

Easy to set up and use, these transmitters measure liquid levels using a standard float gauge.
