Hydrogeological tape measures

Hydrogeological tape measures

Hydrogeological tape measures are intended for measurement of the depth of water level in the observation hydrogeological, producing and other wells casing with metal pipes or observation pipes (with an internal diameter not more than 20 mm) by lowering an electrode in a well on a measured cable.
The level gauge is mounted on the edge of a casing pipe by means of roller hitches. The level gauge connects to a casing pipe (pull head) by a cord with clips for ensuring of electric contact . During unwinding the coil the wire with an electrode sensor falls to the well. At the time of electrode contact with a water surface the light-emitting diode on a cover of the coil will light up and the sound signal will go on. Length of the lowered wire is determined by tags on a cable (depth to water level). Wire length between tags, when necessary, can be measured by the enclosed tape measure.
