Low Range Liquid Level Sensors

Level sensors for measuring very low liquid levels in shallow rivers, weirs, drains, sewers, streams and small tanks which are immersed or mounted on the outside of a tank.

Immersible low pressure sensor for measuring shallow liquid level with a rangeable 4-20mA current loop or high level voltage output signal in level ranges from 80mmH20 up to 160mH2O

Submersible level transmitter for measuring liquid level with a 4-20mA current loop or a 0-10V voltage output plus optional ATEX approval for instrinsically safe use in hazardous areas in ranges from 1mH2O up to 250mH2O.

Submersible Low Range waste water level transmitter with intrinsically safe option for monitoring the level of sewage and effluent in water treatment plants. Available in level ranges from 0.4 up to 100 meters of water gauge.

IP68 low range pressure transmitter for measuring the level of highly contaminated and agressive liquid media with a body made from PP (Polypropylene) or PVDF. Hydrostatic level ranges from 0.4 up to 100 metres of water column.

Flush capacitive ceramic pressure sensor for measuring corrosive and viscous liquid level from levels 0.4 metres of water up to 200 mH2O. This screw-in fluid level transmitter features high overload rating up to 50x and options for all plastic wetted parts.

Three in one hydrostatic level switch, digital level gauge and level sensor with level ranges from 1 mWG up to 600 mWG (3.3 to 1969 ftWG).

Measure vacuum, positive gauge and absolute pressures from -1 bar (-15psi) up to 40 bar (600psi) with this all in one electronic switch, gauge and sensor. Designed specifically for use in the food, drink and biomedical industry for measuring process pressures and vessel contents. Choose dairy pipe or clamp type sanitary process fittings and select a food grade oil fill as the diaphragm isolation fluid. For pharmaceutical installations requiring hazardous dust protection the instrument includes the option for ATEX intrinsic safety.

Water resistant pressure sensor for measuring hydrostatic pressures in the range of 0-0.5 mWC up to 0-100 mWC. An all stainless steel 316L construction with Viton O rings seals and a choice of PUR, PVC or FEP vented cabling. The IMSL is used for measuring groundwater, aquifer, reservoir and borehole water level. The internal silicon strain gauge sensor provides a stable water level reading accurate to 0.1% of span linearity with low hysteresis and repeatability errors.

Marine approved level transmitter with 4-20mA current loop output for measuring the level of contents inside a ships ballast, fuel, liquid cargo or wastewater tanks with optional all CuNiFe construction for sea-water compatibility in ranges from 0.4 mH2O to 200mH2O gauge or absolute.

Submersible stainless steel pressure transmitter ideal for geotechnical surveying with a 19mm diameter for measuring hydrostatic water level in bore-holes. This small diameter level sensor has level ranges from 1 up to 250 metres water column and a 4-20mA current loop output signal.

Combined pressure and temperature sensor with a 1200 baud rate serial data interface as defined by the SDI-12 support group. The S12S is a submersible probe used for monitoring water level and temperature. The SDI-12 digital interface is specially designed for low power, battery operated instrumentation such as on-site environmental dataloggers. Measure the rise and fall of water levels in ranges from 0 to 2 feet up to 0 to 300 feet of water column.
