Liquid Level Sensor Products

Gems liquid level sensors and switches provide high-reliability monitoring and detection of a wide range of fluid media. Requirements can range anywhere from the sensing of cooking oil, to hydraulic fluids, to diesel fuel tanks, to water and wastewater, to biohazards, to even deionized or potable water.

To effectively address such a wide variety of measurement challenges, Gems offers a broad range of contact, non-contact, and non-intrusive liquid level switches and sensors. These are available in multiple technology types, including reed switch-based floats, solid-state electro-optical, conductivity, capacitive, ultrasonic, and piezo-resonant. Multiple liquid level sensing technologies may also be incorporated within a single application. Sometimes, more than one “best fit” solution may also exist, with the ultimate decision simply a matter of customer preference.

Standard catalog products for liquid level sensing include single point level switches, continuous level transmitters, multi-point level switches, and visual level indicators. Detailed specifications on these and other liquid level sensors and switches may be found in the links below.
