Gems Sensors liquid level sensors and switches provide high-reliability monitoring and detection of a wide range of fluid media and applications anywhere from medical reagent level monitoring, to sensing of liquids in food and beverage applications, to hydraulic fluids, to diesel fuel tanks (gas level indicator), to water and wastewater, deionized or potable water, and hundreds more. With a deep portfolio of technology options including reed switch-based floats, solid-state electro-optical, conductivity, capacitive, ultrasonic and guided wave radar, Gems Sensors level sensors and switches can accommodate contact, non-contact and non-intrusive sensing requirements.

Single-Point Level Switches

Single-Point Level Switches

Gems Sensors single point level switches are ideal for reliable and accurate tank level detection. Single point level switches are available in a vast range of sizes, mountings, materials and sensing technologies (from mechanical to no moving parts) which include float-level sensors and switches, electro-optic level switches, capacitive level sensors and switches and ultrasonic level sensors.Learn More About Single Point Level Switches >
Single-Point Level Switches

Multi-Point Level Switches

Multi-Point Level Switches

Gems custom-length multi-point level switches are ideal for monitoring multiple liquid level points within a single tank or for monitoring two or more liquids in a tank. They are available in engineered plastic or metal alloy, a broad range of mounting options and float materials and can be configured with two to seven independent switch actuation levels. Only a single entry point into the tank is required and all electrical wiring emanates from a single source.Learn More About Multi-Point Level Switches >
Multi-Point Level Switches

Continuous Level Transmitters

Continuous Level Transmitters

and ultrasonic liquid level sensing. Level transmitters utilize multiple material combinations make them compatible with most liquid media and challenging fluids (including ultra-pure, dirty, coating, scaling and corrosive types).radarGems continuous level transmitters are are ideal for remote tank measurement in small to mid-size tanks and are available in a variety of sensing technologies: float, Learn More About Continuous Level Transmitters >
Continuous Level Transmitters

Visual Level Indicators & Tank Level Gauges

Visual Level Indicators & Tank Level Gauges

Gems visual level indicators and tank level gauges are ideal for continuous indication of liquid level in storage tanks and vessels where visual indication at the tank is required. Gems SureSite® line represent the trusted, durable, more versatile and safer alternative to sight glasses and feature stainless steel, alloy or engineered plastic housings. SureSite visual level indicators mount externally to the top or sides of tanks and provide easy-to-read continuous level gauging (the LED SureSite can even provide continuous level indication dark environments). Gems also offers PVC, alloy and engineered plastic DIPTAPE indicators.Learn More About Visual Level Indicators >
