- The sensor design complies with fluid dynamics principles, featuring a compact size to minimize its impact on the flow field.
- Equipped with an advanced DSP processor and intelligent processing algorithms, it automatically identifies the flow field state of the water body, meeting measurement requirements in various aquatic scenarios.
- It supports bidirectional flow velocity measurement, ensuring accurate readings whether the sensor is installed in the direction of the flow or against it.
- It supports ultrasonic and pressure-based liquid level measurement, offering high accuracy and stability.
- The IP68 waterproof quick-connect interface ensures convenient on-site maintenance and plug-and-play functionality.
- The Bluetooth 4.0 interface and accompanying APP enable easy debugging and operation from above the well.
- The magnetic switch design facilitates on-site operation and device debugging.
- The dry air device provides dry air connected to the atmosphere, ensuring the accuracy of the pressure sensor.
- It automatically connects to the IoT monitoring platform, enabling remote monitoring and alarms with low operational and maintenance costs.
- Powered by a built-in 7.2V, 170AH disposable high-energy lithium battery, it can operate continuously for over a year with data collected every 10 minutes, offering long maintenance cycles and high safety.
