HL-XW series wireless IoT terminals are industrial grade wireless transmission terminals specially developed by Dalian Hilevel Measurement and Control Technology Co., Ltd. for water level and flow in urban and rural pipeline networks. The design concept is advanced, the protection level is high, and the compatibility is strong. They can be applied to other monitoring sites with high waterproof/dustproof requirements, such as water supply and drainage/oil/heat/gas pipeline network monitoring, groundwater monitoring, and oilfield long-term well shutdown monitoring Liquid level monitoring and other fields can be widely applied.

The wireless IoT terminal is installed on the side wall below the manhole cover, used to receive sensor signals and send data wirelessly to the detection software platform. Industrial grade ultrasonic water level gauges or flow meters are installed underground, and wireless IoT terminals transmit water level or flow data to the monitoring center through a 4G network at fixed times (time intervals can be set); When the water level data exceeds the preset alarm value, the monitoring RTU will report the alarm information to the monitoring center in real time.

The drainage network monitoring system software in the center dynamically displays the water level or flow information of important nodes in the monitoring network of each inspection well, and timely detects the phenomenon of pipeline sedimentation and blockage. And provide early warning information on pipeline network operation, providing decision-making basis for emergency flood prevention work. Diagnose bottleneck pipe segments in drainage networks and provide a basis for network renovation. To provide analytical data for eva1uating the drainage capacity of low-lying and easily flooded areas. Can trace the historical operation status of the pipeline network and assist in accident analysis.
