Product Description
The Water Depth Meter is an essential tool for construction projects, hydraulic engineering, and hydrogeological surveys. It combines a sensitive stainless-steel probe with a durable steel-tape cable featuring a clear measuring scale.
When the probe contacts the water surface, the Water Depth Meter immediately triggers an audible or visual signal, allowing users to read the water level directly. With a minimum resolution of 1 mm and repeatability of ±2 mm, it ensures highly accurate and consistent measurements in both shallow and deep environments.

Key Features of Water Depth Meter
The RanCheng Machinery Water Depth Meter is equipped with a high-precision probe and durable steel tape cable, designed for accurate and stable groundwater measurements. It features dual detection modes-sound alarm and voltage peak indication-ensuring reliable readings even in noisy environments. The ergonomic, freely rotating reel and secure probe holder make operation simple, safe, and convenient.
Advantages
The Water Depth Meter provides multiple practical advantages for complex site monitoring:
Flexible Observation Point Placement
Suitable for deep wells, light well points, or recharge wells, with monitoring points arranged centrally, at corners, or between dewatering wells to ensure comprehensive coverage.
01
Layered Monitoring Capability
Supports installation in multiple aquifers, allowing accurate measurement in sites with two or more water-bearing layers.
02
Optimized Tube Depth
Piezometer tubes can be placed 3–5m below the lowest design water level, ensuring precise groundwater level readings even under low-water conditions.
03
Site-Specific Layout
Enables monitoring along pit perimeters, near important pipelines, slopes, or protective structures, adapting to site complexity and potential risk zones.
04
Durable Cable and Probe Management
Ergonomic reel and secure probe holder minimize wear and tear, making frequent repositioning and long-term monitoring easier.
