Digital Ground Water Level Recorder (Piezometer)

Introduction

Ground water is among the Nation’s most precious natural resources. Measurements of water levels in wells provide the most fundamental indicator of the status of this resource and are critical to meaningful evaluations of the quantity and quality of ground water and its interaction with surface water. Next Sense Technologies made GWLR-01, Ground Water Level Recorder, is a data logger and submersible pressure transducer combination designed for remote monitoring and recording of water level or pore pressure data. The sensor is lowered into the well on a reinforced cable and submerged below the water. Once in place, the initial water pressure reading is synced with the current water level. The unit then monitors the water pressure for changes, and the pressure difference is converted to a change in water level. The entire unit is hermetically sealed to prevent any moisture from getting into the instruments circuitry. The instrument comes along with inbuilt memory and GPRS enabled web telemetry for remote communication of data. Optional rechargeable battery along with solar panel is also available for uninterrupted power even at remote places. The GWLR-01 is used for measuring water levels in bore wells, dams, open channels and lakes.
