New meter performs accurate static water level measurement and monitors falling hydraulic head

Solinst Canada Ltd. Have recently launched the latest addition to their level measurement devices -the Model 101D Water Level DrawDown Meter which indicates static water level, with a second function to monitor falling hydraulic head.

In water level mode, the Model 101D Water Level DrawDown Meter performs accurate depth to water measurements in wells, boreholes, standpipes, and tanks. The drawdown function is used to monitor falling hydraulic head during low flow sampling, pumping and other aquifer/well tests. It also ensures a pump’s intake remains submerged during purging or well development.

The Model 101D includes all the same qualities as Solinst’s Model 101 P7 Water Level Meter, with a simple control added to switch between modes. The 101D has a sturdy reel and frame that Solinst Meters are known for, as well convenient features such as a brake, probe holder, tape guide, on/off sensitivity dial, battery test button, and easy-to-access battery tray for a standard 9V battery.

In water level mode, when the zero point on the probe enters water, an electronic circuit is completed, activating a buzzer and light. In drawdown mode, the circuit is reversed—the buzzer and light are triggered when the probe is in air.

The levels are read from durable, chemical-resistant flat tape, which is accurately laser marked every 1/100 ft. or mm. Tape lengths are available up to 5000 ft. (1500 m). The robust P7 Probe is submersible to 1000 ft. (300 m), and can be easily replaced in the field, if required.
