Overview
New Water Level DrawDown Meter
2 Products in 1
Both static water level and drawdown modes in one meter
One convenient toggle makes it easy to switch between the two functions
Tape lengths up to 5000 ft. (1500 m)
We are pleased to introduce the New 101D Water Level Draw Down Meter, which has all of the same features as our Model 101P7 Water Level Meter, with the added benefit of the new Drawdown Mode, all in one unit. When in DrawDown mode the probe signals in air instead of water. This is a great feature if you need to know when levels in a well are dropping. The 101D Water Level DrawDown Meter also uses our Laser Marked Flat Tape, with standard lengths to 1000 ft (300m).
Applications Ideal for the Water Level DrawDown Meter
Depth to water in wells, boreholes, standpipes and tanks
Drawdown monitoring during:
- Low flow groundwater sampling
- Well development and purging
- Dewatering applications
- Pumping, slug, hydraulic conductivity, step and other aquifer/well tests

Tape & Probe Specifications
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 and Other Options
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.
Other Options
Carrying Case:To help maximize the life of the Meter, optional small and medium padded nylon carrying cases are available. Their design has a convenient shoulder strap, zippered top and front pocket, and a grommet in the base to prevent moisture build-up.
Replacement Parts:Replacement probes, tapes, faceplates and other spare parts are available.
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.
