The 101D Water Level DrawDown Meter has all of the same
qualities as our well-known 101 P7 Water Level Meter, with the
added feature of a drawdown mode. One simple toggle switches
between static water level and drawdown measurements.
Water level mode allows 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.
Laser Marked Flat Tape The 101D Water Level DrawDown Meter uses corrosion and
chemical-resistant flat tape. The tape is non-stretch and high in
tensile strength. The thick dog bone design prevents adherence
to wet surfaces and allows the tape to hang straight. It is also
easy to repair and splice. The 3/8" (10 mm) tape comes with
permanent laser markings every 1/100 ft. or each millimeter, in
lengths up to 5000 ft. (1500 m).
LM2: Feet and tenths: with markings every 1/100 ft.
LM3: Meters and centimeters: with markings every mm.
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. The tape seal plug design allows the
probe to be quickly and easily replaced if required.
Reels With a well-balanced frame, comfortable carrying handle, and
handy probe holder, the standard reels are ergonomic and easy
to use. They are sturdy and smooth running. The battery is
housed in an easy-access drawer in the front of the reel for quick
replacement. The reels are equipped with an on/off sensitivity
switch, Water Level/Draw Down switch, light, buzzer, battery
test button, brake and a tape guide stored on the frame.
Tape Guide/Datum A tape guide is provided with each Meter to prevent damage
to the tape from rough edges. It also ensures easy, consistent
measurements regardless of who takes readings. It can also
provide support for hanging small reels on the casing.
