HydroScientific West offers Sommer's RQ-30 non-contact system which measures discharge by RADAR technology. The unique feature of the RQ-30 system is the continuous capturing of flow velocity which enables an exact discharge measurement and evaluation of specific discharge situations. In case of flood, the system measures the exact discharge and because of the non-contact radar technology, there is no damage of the measurement system by bed loads or trees. If the floodplains get flooded the discharge is determined by combining several RQ-30 sensors to one system. Applications include hydrographic discharge measurement, preservation of evidence of the discharge quantity in power plant operations, and monitoring storm-water overflow in canals.
Some more features include:
- Maintenance free
- No structural construction in the water needed
- Low power consumption allows solar cell instigation
- Detection of flow direction
- Measurement range 0.30 to 15 m/s
- Recognition of hysteresis effects
- Measurement in back water situation
- Recognition of vegetal invasion
- Measurement in tide dependent rivers
- Own measurement interval or externally triggerd
- Optional RQ-30a: analog output 4 to 20 mA
