RS Hydro is a manufacturer of level sensors and transmitter for various pressure, ultrasonic, open channel, radar and capacitance level measuring applications. Hydrostatic pressure level sensors from RS Hydro are submersible sensors used for measuring the level of liquids (including corrosive liquids) in deep tanks or water in reservoirs. RS Hydro's capacitance level sensors are rugged and contain no moving parts making them easy and simple to use and maintain.

Innovative Solutions design and manufacture level sensors for a variety liquid level measuring applications. These include capacitance sensors, float level sensors and guided wave radar level transmitters. The CS01 capacitance transmitter features a simple four button calibration to set for whatever media it is measuring. Its 316 stainless steel probe comes in lengths up to 60" and is available in NEMA 4 or explosion-proof housings.

American Magnetic manufactures a vast selection of liquid level measuring instruments including liquid helium level sensors, standard AMI liquid level sensors, and non-cryogenic liquid level measurement sensors.

Liquid level sensors from Gill Sensors are used for a variety of applications such as motorsport formulas, military vehicle and unmanned aerial vehicles (UAVs), automotive research, process industry applications and more with features including configurable 0-5V analog output, full integrated electronics and no moving parts. Custom designs are also offered.
