Radar flow meter RQ-30D

volumefor waterRS485

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. 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 in the water - Recognition of flow direction and hysteresis effects - Measurement in tidal waters - Measurement in backwater situations - Measures even where weed growth prevails and sensor is not affected by turbidity - Measuring range from +/- 0.10 to +/- 15 m/s (depending on the flow conditions) - Analogue outputs from 4 to 20 mA (optional) Fields of application The main advantage of the RQ-30d is that the discharge can be measured more precisely, especially in rivers and streams where the flow velocity is distributed inhomogeneously over the cross-section. Varying velocities can be observed particularly in very broad streams as well as in situations, where the measuring site is located close to a river bend, an incoming river or watergates. In order to capture the complete flow-profile even more accurately, the RQ-30d system measures multiple individual flow velocities dispersed over the width of the body of water.
