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)
