This low pressure sensor, broadly used for settlement measurement and water level/water pressure measurement in boreholes. It has a diameter of 30 mm which is conveniently designed to measure water level, and water pressure in boreholes. This pressure sensor is used for applications in which maximum hydrostatic head (height of water level above piezometer location) is less than 7 m over the sensor diaphragm.
