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

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.

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.

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.

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.

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.

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.

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.

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 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

Water depth gauges for quick and simple measurement of water depth in wells and boreholes. A useful tool for determining water level datum for calibrating hydrostatic level sensors or any other type of liquid level sensor. These portable devices also offer an economical alternative to installing liquid level sensors to each borehole or well since they are easily carried from one location to another.
