Features：
* 20 coordinate points to describe cross section of the river�s shape.
* One instrument can measure the velocity, depth and conductivity simultaneously.
* Velocity Range: 0.02mm/s to 12m/s bi-directional, accuracy is 1%.
* Depth Range: 0 to 10m.
* Measure velocity in both forward flow and back flow.
* Depth is measured by both the pressure sensor and ultrasonic level sensor principles.
* With barometric pressure compensation function.
* IP68 Epoxy-sealed body design, designed for under water installation.
* RS485/MODBUS output, can connect to computer directly.
