Piezometer Ground Water Level Recorder

Piezometer Ground water level is used to measure or monitor the water level in the Borewells, Railway bridges, and many more as per the latest Centre for Ground Water Studies(CGWS}Norms. It has a telemetric system to make the data available on cloud base servers and CGWS central server also The GWL-VE300 series of submersible liquid level transmitters use the diffused: silicon piezoresistive pressure sensor with stainless steel isolation membrane as the signal measuring element to accurately measure the hydrostatic pressure that is proportional to the depth of the liquid level. The transmitter has an RS-485 communication interface that supports the standard MODBUS-RTU protocol. The communication address and serial port attributes can be set, and the communication distance is up to 2000 meters, which can realize remote monitoring. The transmitter can be directly put into the liquid to measure the height of the liquid level from the end of the transmitter to the liquid level, with high accuracy and easy to use; after long-term aging and stability assessment, the performance is stable and reliable; it can be widely used in urban water supply and drainage, Sewage treatment, rivers and reservoirs, and other fields.

Piezometer  Working Principle

GWL VE300 Series Piezometer liquid level transmitter is put into the liquid. The water pressure eats the position of the transmitter acts on the diffused silicon sensor through the pilot hole. The liquid level signal can be obtained by measuring the pressure. After the sensor samples the liquid level signal, it is transported first.
