>

Application scope:
·Storm monitoring, wastewater treatment, natural rivers and streams, municipal water supply and drainage flow rate, water level, temperature, and flow measurement
·Water loss/infiltration monitoring, irrigation process monitoring, industrial pollution measurement
·Research on estuaries and tides, fisheries/water conservancy, and coastal erosion
·Sewage/Underdrain Process Monitoring · Road Drainage Monitoring
·Research on Canal Process and Monitoring of River Process

Instrument features:
1. It can measure the flow rate, velocity, water level, water temperature, and cross-sectional area of pipelines, channels, and natural rivers.
2. Can provide instantaneous and cumulative flow values
3. The instrument has a built-in 256M data storage and can query 2-month history records through the touch screen.
4. Communication interface: MODBUS-RTU
5. Sensors can work for a long time in harsh environments and sewage quality
6. Environmental conditions: No mechanical rotating parts, no mud blockage or entanglement of water plants, debris, etc
7. Sensor power consumption: When measuring flow rate: current<60mA, power consumption<1W;
8. Probe housing can withstand sealing pressure: greater than 4.5 atmospheres, capable of working underwater up to 20 meters
9. Display screen 4.3-inch touch screen, easy to display and operate.
