Hydrostatic level sensors for measuring ground water level in small diameter bore-holes.
These sensors are typically used for geotechnical research applications where many small holes are drilled into the surface to test for natural or manmade effects on groundwater level.
LMP305 Borehole Level Transmitter - Submersible stainless steel pressure transmitter ideal for geotechnical surveying with a 19mm diameter for measuring hydrostatic water level in bore-holes.
MTM/N10 10mm Diameter Submersible Miniature Pressure Transducer - MTM3000 Miniature Level Sensor specially designed for inserting down very small boreholes in wells, dams and many geophysical research applications.
LMK306 Ground Water Level Transmitter - IP68 sealed hydrostatic level transmitter with a 17mm diameter for lowering into ground water boreholes for environmental monitoring of water level.
