Contact-free discharge measurement for channels and open rivers - Model RQ-30

The RQ-30 radar sensor continuously measures the discharge of rivers and channels. The device combines two non-contact radar measurement methods to determine the surface velocity and water level.
Because of the contact free measurement the system cannot be harmed by sediments and floating refuse. The result is very low maintenance and an increased reliability, especially in flood water situations.

Special features:
- Maintenance free
- No need for a structure in the water
- Fully operating even in flood water situations
- Solar powered due to low power consumption
- Detection of flow direction
- Velocity range of 0.30 to 15 m/s
- Recognition of hysteresis effects
- Measures in a back water situation
- Also measures vegetal invasion
- Measures in tide influenced rivers
- Automatic installation angle correction
- Optional: analog outputs 4 to 20 mA
