Use high-frequency sound waves to detect chemical level.

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

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

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

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.

Mount these switches from outside the tank through 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 outside the tank.

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

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

Short probes are built into the tip of these switches.

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.

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

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.

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

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

FM and C-FM approved, these transmitters safely measure liquid levels where explosive gas or dust may be present. Set them at the bottom of your tank in applications that make traditional mounting difficult.

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