Sommer RQ Radar Flow and Velocity Sensor 20787

PART NO: SM-20787

Autonomous Discharge measurement System RQ-30 ADMS, 35m, with integraded data logging and transmission.

Ideal all-in-one system with integrated data logger and 3G/4G communication for non-contact discharge measurement in open rivers and channels. Simply mount the sensor on bridges, on the roofs of closed canals or channel superstructures.

Main Features:

  • Integrated data logger (MRL-Family)
  • Integrated 2G/3G/4G communication
  • Contact free measurement, maintenance free system
  • No structural work is necesary in the water
  • No threat to the system through flooding
  • Low power consumption enables operation using solar cells
  • Recognition of flow direction
  • Measuring range from +/- 0.10 to +/- 35 m/s (depending on the flow conditions)
  • Recognition of hysteresis-effects
  • Measurement in backwater situations
  • Measures even where weed growth prevails and sensor is not affected by turbidity
  • Measurement in tidal waters
