The RQ-30 non-contact system measures the 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. The RQ-30 system measures from very low water depth up to the maximum possible discharge of a 100-year flood or even greater. To measure any discharge situation at rivers, torrents, creeks, mountain torrents or open channels the RQ-30 is a unique and reliable system.

  • RQ-30 discharge sensor: Measures the flow velocity, integration of radar level sensor and calculation of the discharge
  • Radar level sensor
  • Protective casing for both sensors
