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 10 mm (3/8") tape comes with permanent laser markings each millimeter or every 1/100 ft., in lengths up to 1500 m (5000 ft.).

LM2: Feet and tenths: with markings every 1/100 ft.
LM3: Meters and centimeters: with markings every mm

Lengths available to 1500 m (5000 ft.).


Water Level DrawDown Probe

The 101D uses the same probe as the 101 P7 Water Level Meter, which is submersible the full length of the tape. 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.
