Water Level Meters – Tape
101 P7 Water Level Meter
The Solinst 101 Water Level Meter with P7 Probe features an extremely durable, laser marked PVDF flat tape, with an enhanced dog bone design that is thicker, reducing adherence to the side of well casing.
101 P7 Submersible Probe measures water levels and total well depth
More consistent measurements with sensor located at the tip of probe
Solinst PVDF flat tape has increased tensile strength and electrical efficiency
Enhanced Laser Marked Tape Features
- Durable PVDF non-stretch tape
- Improved electrical properties
- Thicker dog bone design prevents clinging to sides of the well
- Permanently laser marked every 1/100 ft or each mm
The PVDF flat tape is laser marked every 1/100 ft or each mm; lengths up to 5000 ft (1500 m). New flat tape has increased tensile strength and electrical efficiency by using 6 strands of copper coated stainless steel and 13 strands of stainless steel in each conductor. The P7 Water Level Meter Probe is engineered to allow submersion to 1000 ft. (300 m). Sensor at the tip of the probe provides consistently accurate measurements in wells, boreholes, and cascading water, with almost zero displacement.
101B Water Level Meter
Solinst 101B Water Level Meters feature a basic design, making them a very economical option for depth to water level measurements. The 101B uses polyethylene flat tape, heat embossed in centimeter increments. Tape lengths available are 30 m, 60 m, and 100m. The robust stainless steel P1 Probe is ½” (12.7 mm) in diameter.
Bladder Pumps for Groundwater Samples

Once you’ve measured your water level, take a groundwater sample using a Solinst Bladder Pump. Bladder Pumps ensure no air/water contact during operation, providing representative groundwater samples and excellent VOC sample results.
