　　 Water Body Monitoring:

　　Based on millimeter-wave radar level gauges, flow meters, and flow meters, frequency-modulated continuous-wave radar (FMCW) technology and K-band planar microstrip array antenna technology are used to measure the liquid level and surface. It integrates vertical angle compensation, flow velocity filtering algorithm, signal strength detection, RS485/RS232 communication, and wireless communication functions. This energy-saving, non-contact measurement technology makes the measurement unaffected by temperature gradients, water vapor on the water surface, pollutants in the water, and sediments; the optimized algorithm can make the measurement results more accurate. Compared with traditional water level gauges, it has the advantages of small size, easy installation, and low maintenance.

　　 Radar Water Level Gauge Using high-frequency microwave radar technology, the sensor emits electromagnetic waves to irradiate the water surface and receives the echo, thereby analyzing and obtaining information such as the distance and azimuth from the water surface to the electromagnetic wave emission point. This product can effectively assist in monitoring the water level change status, realizing a technological leap of the water level gauge towards high precision (millimeter level), high reliability, and easy installation; with built-in water surface fluctuation filtering algorithm, it provides the monitoring unit with more accurate and stable water level information, and has the advantages of high precision, low power consumption, and small size compared to traditional radar level gauges.

　　Mainly applicable to hydrological monitoring of natural waters such as rivers, reservoirs, lakes, canals, and channels, urban waterlogging road waterlogging, flood control and flood prevention, underground pipe network water level monitoring, and drainage pipe networks and drainage outlets.

　　 Radar Flow Meter Using advanced planar microwave radar technology, it measures the flow velocity and water level of the water body in a non-contact manner. According to the built-in software algorithm, it calculates and outputs the real-time cross-sectional flow and cumulative flow, and can be used for flow measurement in scenarios such as rivers and canals. This product uses microwave technology for flow velocity and water level measurement, and is not affected by temperature gradients, pressure, air density, wind, or other meteorological environmental conditions, and is not affected by sewage corrosion and sediment, and can operate stably around the clock. This product also has the advantages of low power consumption, small size, and easy installation and maintenance, making it very suitable for field measurement environments.

　　Mainly applicable to hydrological monitoring of natural waters such as rivers, reservoirs, lakes, canals, and channels, urban waterlogging road waterlogging, flood control and flood prevention, underground pipe network water level monitoring, and drainage pipe networks and drainage outlets.

　　 Radar Flow Velocity Meter Specifically used for surface flow velocity monitoring in places with fluctuating water flow such as natural rivers, canals/culverts/pipes. The product uses planar microstrip radar technology and accurately extracts the water flow velocity through proprietary backend processing technology, realizing non-contact, unmanned automatic monitoring in the fields of hydrology, water conservancy, irrigation, and water supply.

　　Mainly applicable to natural river flow velocity detection, urban flood monitoring during flood seasons, and water flow velocity monitoring in various canals/culverts/pipes. It can be combined with water level detection for hydrological monitoring.

　　 Water Quantity Measurement:

This instrument integrates measurement, calculation, and display, uses ultra-low power consumption technology, a single battery can be used for more than 6 years, can achieve accurate measurement of the minimum flow rate of 0.01m³/h, and uses wired M-BUS, wireless 4G\5G\NB communication networks for data transmission to form an online monitoring system. The product has the characteristics of beautiful appearance, convenient installation, accurate measurement, stable operation, strong anti-fouling and anti-corrosion ability, long service life, small pressure loss, and economical practicality.

　　 Water Quality Monitoring:

　　Applying advanced water quality analysis and detection technology, artificial intelligence, and big data analysis application technology, a water quality automatic monitoring system has been formed, providing a complete set of intelligent monitoring solutions for environmental and water supply monitoring and management. The product uses IOT sensors, with advantages such as small size and high integration.

　　The multi-parameter water quality analyzer can continuously monitor various water quality parameters including residual chlorine, turbidity, pH, and temperature. It has flexible configuration options, complete communication functions, small footprint, easy installation, and lower maintenance. It is specially designed for unattended applications and can be widely used in drinking water pipelines, secondary water supply, integrated urban and rural water supply, and water source protection areas for water quality monitoring.

　　 Switchgear Temperature Measurement:

　　Passive wireless temperature measurement for switchgear is suitable for online temperature monitoring of various types and voltage levels of switchgear. It has reliable high-voltage isolation, anti-strong electric field, magnetic field interference, and good thermal stability, as well as the characteristics of no power supply required, small size, long service life, and maintenance-free. It monitors the temperature changes of hot spots such as switch contacts and busbar connections in real time, can monitor abnormal heating, prevent the accumulation of faults, and provides scientific data basis for "state maintenance" of switchgear through temperature history records. It is of great significance to the safe operation of switchgear equipment.
