PIEZOMETER NON TELEMETRY

A piezometer and a DWLR (Dial Water Level Recorder) are both devices used in hydrology and geotechnical engineering for measuring groundwater levels or piezometric pressure in wells.

Piezometer:

A piezometer is a device specifically designed to measure the pressure of groundwater at a specific point within an aquifer. It typically consists of a small-diameter tube inserted into a borehole or well, reaching the depth of interest where groundwater pressure needs to be measured. The piezometer tube is sealed at the lower end, and the water level inside the tube indicates the pressure at that depth. This pressure measurement can provide insights into the groundwater level, flow direction, and aquifer characteristics.

 

DWLR (Dial Water Level Recorder):

A DWLR is a type of water level measuring device used to monitor changes in water levels within wells or boreholes over time. It consists of a float connected to a tape or cable, which is wound around a drum or reel. As the water level changes in the well, the float moves accordingly, causing the tape or cable to wind or unwind on the drum. This movement is recorded using a dial or digital system, allowing for continuous monitoring and measurement of groundwater levels
