22,000 - 38,000 Per piece
A piezometer is a geotechnical instrument that measures water pressure and water level changes underground. It's a tube that's inserted into the soil and can be used in dams, pipes, and other conduits. Piezometers are an essential tool for monitoring and controlling the properties of groundwater when there's an excavation, borehole, or drainage. They can also be used to: Estimate the local depth to the water table Monitor the performance of embankments treated using vacuum preloading Assess the immediate zone of influence of longwall mining on groundwater
