Automatic Water Level Recorder

Piezometer : Water level gauge Model IG 1402 with 20m integral cable and vent tube

Model IG-1402 Automatic Water Level Recorder is designed for accurate, remote monitoring of ground water level in a reservoir/ borehole, coastal and inland waters, ports, wells and rivers. It can also be used for recording water level in canals, open channels, sumps and underground and overhead tanks/ sumps.

It essentially consists of a vibrating wire pressure sensor provided with a vent tube of required length running parallel to the sensor cable. The vent tube and cable are routed through a protective tube to a Digital read out unit, for displaying the water level in its engineering units. A special cylindrical filter with conical tip is provided to give more surface area to the sensor. The filter is fixed on to the sensor body through a threaded connector which may easily be removed for saturation. Option of disc filter is also available.
