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 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.

Use the included bracket to mount these switches to the inside 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.

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.

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

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

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

Certified by 3-A and EHEDG (European Hygienic Engineering and Design Group) to meet sanitary design standards, these switches detect levels of air, foam, liquid, and solids in tanks and pipelines. They’re often used in brewery, food and beverage, and pharmaceutical environments to trigger pumps and valves in automated lines.

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