The 101D water level drawdown meter, from Solinst, provides accurate depth to water measurements in wells, boreholes, standpipes, and tanks. The added drawdown function monitors falling hydraulic head during low flow sampling, pumping and other aquifer tests. Levels are read from durable flat tape, accurately laser marked every mm or 1/100 ft. Tapes are available up to 1500 m (5000 ft). The probe is submersible to 300 m (1000 ft).
