Water Level Meter
Sensors One supplies Solinst 101 P7 water level meters and delivers turnkey monitoring well projects. We have over 10 years of experience designing and implementing monitoring systems. Our team drills and equips monitoring wells, installs and commissions instrumentation, trains site personnel and provides ongoing service. Sensors One is an authorized RST Instruments distributor in Kazakhstan, Kyrgyzstan and Uzbekistan.
The Solinst 101 P7 is a portable meter for manual depth-to-water measurements. Its metric tape is laser-marked in 1 mm increments.

Measurement Principle and Instrument Design
The Solinst 101 P7 measures the distance from a reference point, such as the top of the well casing, to the water surface. Water contact closes the circuit in the P7 probe and activates a light and buzzer. The operator reads the depth from the tape. Sensitivity can be adjusted to suit water conductivity and reduce false signals from cascading water.
The flat PVDF tape has permanent laser markings and raised edges that help keep it from sticking to wet casing. The metric LM3 scale is marked in 1 mm increments. The sensing element sits at the tip of the stainless steel probe. The probe can be replaced, and the tape can be repaired by splicing.
The reel includes a brake, tape guide, probe holder and battery test button. A front-access drawer makes the 9 V battery easy to replace.
When requesting a quote, specify the well depth, required tape length and project country. Sensors One can recommend a configuration and scope well drilling, instrumentation installation and system commissioning for the project.
