Product Description

What's this product?

     The manhole water level monitor is a battery-powered device featuring ultra-low power consumption, IP68-rated protection, and wireless communication capabilities. It is specifically designed for monitoring applications in harsh environments such as manholes where power supply infrastructure is unavailable.
     The device is equipped with a high-definition LCD screen for real-time data viewing and supports 4G wireless communication. Users can remotely monitor data through a cloud platform. Powered by long lifespan battery, it features easy installation and stable operation.

What pain points can my product resolve?

    Real time monitor the water level in the manhole, configure alarm parameters.

    Remote monitoring of reservoir water levels, avoid overflow and flood. 

    Water tank leak warning.

Features

1. Wide applicability across multiple operational environments.

2. Supports real-time alerting and remote device configuration.

3. Ultra-low power consumption and long lifespan.

4. With an IP68 protection rating,waterproof and moisture-resistant.

5. Data transmission employs 4G wireless communication.

6. Non-contact measurement effectively reduces the impact of       sediment accumulation, debris, and other factors on the               equipment, thereby reducing maintenance frequency.

Functions

Radar

The Radar Water Level Sensor is independently developed by our company, utilizing FMCW (Frequency-Modulated Continuous Wave) technology with a 60GHz millimeter-wave radar signal as the carrier wave. The product features high measurement accuracy, low power consumption, compact size, and lightweight design. Its measurement process remains unaffected by environmental factors such as temperature, air pressure, sediment, dust, river pollutants, surface floating debris, or atmospheric conditions, while also demonstrating strong wind resistance and anti-vibration capabilities. The optimized algorithm ensures enhanced precision and stability in measurement results.
