DISCHARGE RADAR SENSOR RQ-30D

DISCHARGE MEASUREMENT FOR WIDE RIVERS WITH INHOMOGENEOUS DISTRIBUTION OF FLOW VELOCITY

With the system of one master-radar sensor and several slave-radar sensors the velocity is measured at several spots throughout the whole water cross-section. Therefore a very high accuracy of the discharge measurement is guaranteed also for very wide water bodies.

Description

FEATURES AND ADVANTAGES

  • Discharge measurement with high accuracy – ideal use for very wide rivers with inhomogeneous velocity distribution
  • One water level measurement and multiple, individual velocity measurements
  • Well-proven RQ-radar technique: non-contact measurement, maintenance-free system, flood-proof
  • No structural work is necessary for the water
  • Recognition of flow direction and hysteresis effects
  • Measurement in tidal waters
  • Measurement in backwater situations
  • Measures even where weed growth prevails and the sensor is not affected by turbidity
  • Measuring range 0.08 … 16 m/s (depending on the flow conditions)
  • Analog outputs from 4 to 20 mA (optional)
