Product Description

Portable 300 Meter Well Water Depth Meter Level Indicator Sensor


The Well Water Depth Meter provides the most accurate way to measure water levels, used to measure the water level in wells, boreholes and water pipes, particularly suitable for the observation of groundwater level in hydro power projects and artificial inspection of dam body infiltration line. According to the difference between the reel material and the measured depth, it is mainly divided into the following three models: VLS 700, VLS 701, and VLS 702. VLS700 is the plastic reel material, the measurement range is 30m-400m. VLS701 reel material is  the metallic, measurement range is 30m-400m, easy to hand hold and longer serive life. VLS702  the upgrade is the reel with draw-bar, easy to pull away, the measurement range is suitable for over 400m steel ruler.



The reliability of Votesen Water Level Indicators is second to none when it comes to accuracy, precision, and durability. Standard technical parameters make these Water Level Indicators ideal for field use.

The product consists of three main components: Probes, Reel and Steel Rulers. When the probe touches the water surface, an electric potential is generated in the water level gauge. The board receives the signal and then emits a sound and light indication. The height value between the ground and the water surface can be easily distinguished.
