VWP-G Smart Submersible Water Level Meter with RS485 Output and Automatic Barometric Compensation
VWP-G Smart Submersible Water Level Meter is designed for long-term installation in piezometer tubes of hydraulic structures or geotechnical slopes. It measures water level variation inside piezometers and can also be used for long-term monitoring of water level changes in reservoirs, rivers and lakes. The sensor adopts a full stainless steel structure and has a compact size of 24 x 136 mm, making it easy to install in piezometer tubes larger than 1 inch. It outputs RS485 digital signals, supports automatic barometric pressure compensation and synchronously measures the temperature at the embedded point.
