QTC403-L Fire Hydrant Intelligent Monitoring Device

The QTC403-L fire hydrant intelligent monitoring device adopts micro-power design, which can be applied to the field or application scenarios without mains power supply, such as water supply and drainage pipe network, pumping station, fire fighting pipe network, etc. for water pressure and water flow monitoring; the The device uses the NB-IoT wireless communication method to remotely transmit data such as pressure, accumulated flow, temperature, and battery power to the back-end server management platform to realize remote real-time positioning and monitoring of the pipe network. Big data can be realized through the platform's alarm data analysis and statistics. Display and other functions.
