- Replacement tapes are interchangeable with other Meters
Overview
The 101D Water Level DrawDown Meter uses a corrosion resistant stainless steel probe connected to clearly marked flat tape, fitted on a well-designed reel. It is powered by a standard 9 volt battery.
In water level mode, when the zero point on the probe enters water, an electronic circuit is completed, activating the buzzer and light. The depth to water is then read off the tape. In drawdown mode, the circuit is reversed—the buzzer and light are triggered when the probe is in air.
The battery test button can check the circuit in both water level and drawdown modes. The on/off sensitivity control allows the buzzer to be turned down in cascading water and ensures a clear signal in high and low conductivity conditions.
Water Level DrawDown Probe
The 101D uses the same probe as the 101 P7 Water Level Meter, which is submersible up to 1000 ft. (300 m). The sensor at the tip of the probe provides consistent measurements with almost zero displacement. A protective shroud is included on the probe. The tape seal plug design allows the probe to be quickly and easily replaced if required.
An optional carry case is available to purchase separately.

FAQ's
The P7 probe is pressure rated and can be entirely submerged up to 300m, so can be used to measure total well depth. The zero point on this probe is very near to the probe tip and therefore has near to zero displacement.
Size: 16mm x 137mm
Weight: 128g
The P7 probe connects promptly to the Tape seal plug of the Solinst PVDF Laser Marked flat tape used and, if required, the tape seal plug can be replaced with ease.
The P2 probe is used for tagging the water level and therefore should ideally not be submerged, but has a shielded design to significantly reduce false readings in descending water. The zero point is near the middle of the probe so more displacement may occur.
Size: 14mmx190mm
Weight: 200
The P2 probe is permanently installed onto the heat embossed high quality polyethylene tape.
Both use a flat tape which come with markings every millimetre or 1/1000 ft and have a thick dog-bone design to deter from attachment to wet surfaces.
