Product Description

What's this product?

     The manhole water level monitor is an intelligently designed integrated instrument, This product employs a low-power consumption design which utilizes a silicon piezoresistive level sensor with stainless steel isolation diaphragm as its water level signal measurement element, By utilizing a high-precision AD converter to acquire the water level signal, zero-point and temperature performance compensation for the water level is achieved across a wide temperature range. Powered by a quickly replaceable, high-capacity and long-lasting lithium-thionyl chloride battery pack, Suitable for indoor, outdoor, or other environments without mains power.

     The product can be widely used in petroleum and petrochemical, metallurgy, environmental protection, gas, fire, municipal, chemical, shipping, power, process control, sewage treatment, emergency rescue monitoring and other industries.
     The product utilizes 4G or NB-IoT wireless communication technology to remotely transmit data to the backend management platform, Realize functions including real-time monitoring of on-site water level data, alarm handling and statistical analysis.

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.
