1. Product Introductions

    Accurate liquid level monitoring plays a crucial role in many fields such as urban drainage and industrial production. However, traditional liquid level monitoring equipment often exposes many limitations when facing harsh and non powered environments such as manholes.

    The product adopts advanced lithium battery power supply technology, featuring a unique ultra-low power consumption design that enables long-term stable operation without external power sources, effectively addressing power supply challenges in harsh environments. With an IP68 protection rating, it is completely dustproof and capable of prolonged immersion under water pressure, making it ideally suited for complex and demanding applications such as manholes.

2. Measurement principle

The integrated inspection well water level monitoring instrument is used for real-time water level monitoring in urban drainage systems, manholes and underground pipelines. Its working principle combines the advantages of two technologies (radar wave measurement and hydrostatic pressure sensing) to enhance measurement accuracy and reliability.

The radar serves as the primary measurement unit, providing non-contact, high-precision liquid level data. The hydrostatic sensor acts as the auxiliary unit, offering redundant data and calibrating potential radar errors (e.g., poor liquid surface reflection conditions).

Using algorithms such as weighted averaging and Kalman filtering, the system combines real-time data from both sensors to output the optimal liquid level value. For instance, if the radar fails due to foam or vapor interference, it automatically switches to hydrostatic data. Conversely, if the hydrostatic sensor malfunctions due to silt blockage, the system relies on radar data instead.
