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.
The followings are types of single point level switches.
Capacitive Single Point Level Switches
Gems Capacitance sensors are frequency-tuned for liquid detection. Most are noncontact models that sense from outside a fluid vessel's wall and offer adjustability to operate accurately with both aqueous and non-aqueous liquids.
Capacitance Switch Models
- ULS-200
- CAP-3
- CAP-300
Float Single Point Level Switches
A float level sensor contains a float magnet that travels freely along a stem as the level of liquid rises or falls, and a switch is activated based on the magnetic field that is generated.

Ultrasonic Single Point Level Switches
Ultrasonic switches are non-contact and work by emitting high frequencies that are reflected back and measured. Gems ultrasonic switches and transmitters are ideal for applications requiring solid-state level measurement, such as those with ultrapure, dirty, coating, scaling, or corrosive-type liquids.
Ultrasonic Switch Models
- XLS-1
