Liquid Level Sensors

Liquid level sensors and probes for measuring and controlling hydrostatic fluid level in liquid storage tanks, boreholes, reservoirs, rivers, waterways, tidal water or sea water. Find liquid level instrumentation compatible with a wide range of media types such as water, saltwater, wastewater, diesel, petroleum, chemicals and caustics.

Specify your liquid level sensor requirements

Product Categories

Screw-In Sensors for Monitoring Level of Liquids

Threaded process connection hydrostatic transducers and transmitters for mounting on the outside wall of a liquid storage tank to measure the head of fluid above the mounting point. Select the type of sensor compatible with your application such as a flush diaphragm for thicker liquids or a plastic process connector with a ceramic diaphragm for corrosive chemicals.

Waterproof Sensors for Measuring Hydrostatic Level

Permanent Immersion transducers and transmitters for lowering into a tank, borehole, river or reservoir. Choose sensors with different diameters depending on the stilling well diameter. Specify construction material for different media types such as duplex stainless steel, PVC or PVDF housings with PVC, PUR or FEP cable.

ATEX Approved Liquid Level Sensors for Hazardous Areas

European hazardous area approved sensors for liquid level measurement in intrinsically safe installations on petrochemical, pharmaceutical, landfill and sewage treatment sites. Find hydrostatic transmitters for use in zone 0 and 1 classed hazardous areas where volatile gas and vapour maybe present.

Open Diaphragm Level Sensors for Liquid Waste

Exposed sensing membrane transmitters and transducers for fluids containing sludge and other types of waste which can build up inside the pressure ports reducing performance and sensitivity. Choose electrical connections to protect from wash down, flood or permanent immersion.

Brackish Water IP68 Depth and Level Sensors

Select options for sensor housing material on IP68 rated transmitters and transducers suitable for use with tidal and coastal sea water. Choose a compatible sensor for longer life performance against saline liquid corrosion.

Milliamp Output Level Transmitters

Level Transmitters with robust 2 wire 4-20mA current loop outputs which are submersible or can be externally mounted to a tank for measuring liquid depth by sensing the hydrostatic head pressure.

Voltage Output Level Transducers

Level Transducers with amplified voltage outputs which are submersible or can be externally mounted to a tank, where a high level voltage output is required for sensing the liquid depth by measuring the hydrostatic head pressure.

Millivolt Output Level Transducers

Fluid level transducers with low level millivolt outputs which are submersible or can be screwed into the outside of a tank. Strain gauge output level sensors are typically used on remote installations which require low power consumption for interfacing with data loggers and telemetry systems.

Digital Output Level Sensors

Digital interface level sensors with a serial digital interface which are submersible or can be externally mounted to a tank for measuring liquid depth by sensing hydrostatic head pressure
