1.High precise, non-touching level measurement. Without impact on flow velocity.
2.Low sensor power consumption，easy installation and orientation，application wildly.
3.Widely used in wall hanging right-angle rectangular weir, triangular weir, parshall flume and so on.
4.Easy operation, no need to calibration the input signal, only few parameters should be set.
5.Flow integrating instrument possess data storage. When power off it can save 10 years. Data can be also saved by SD card.
6.According to condition，sensor can choose anti-erosion, anti-explosion, small blind area，ultra low power consumption or wild range
