Product Introduction

The KH.YLS Submersible Pressure Water Level Gauge is a fully sealed, high-precision liquid level sensor designed for long-term monitoring of rivers, reservoirs, groundwater wells, industrial tanks, and other liquid bodies. It integrates a highly stable piezoresistive pressure sensor with an intelligent transmitter circuit, digital temperature compensation, and nonlinear correction technology.

This advanced design ensures exceptional measurement accuracy, long-term stability, and durability even in harsh conditions such as sewage treatment plants, chemical factories, or high-humidity outdoor sites. The KH.YLS is compact, easy to install, IoT-ready, and compatible with multiple communication interfaces for seamless integration with hydrological, industrial, and smart city monitoring systems.
