FEATURES AND ADVANTAGES

• Non-contact, maintenance-free measurement system
• No structural work is necessary for the water
• No threat to the system through flooding
• Low power consumption enables operation using solar cells
• Recognition of flow direction
• Measuring range 0.08 … 16 m/s (depending on the flow conditions)
• Recognition of hysteresis-effects
• Measurement in backwater situations
• Measures even where weed growth prevails and the sensor is not affected by turbidity
• Measurement in tidal waters
• Automatic angle measurement
• Optional (RQ-30a): analog outputs from 4 to 20 mA

FIELDS OF APPLICATION

The RQ-30 enables discharge measurement for rivers, streams, open channels, and canals for which continuous monitoring is desired. Thanks to the non-contact radar technology the measuring equipment is not susceptible to contamination, debris, or driftwood in the water. Furthermore, the non-contact measurement warrants very low maintenance and fail-safe operation, especially during high water or flooding.

 

IMPLEMENTATION

The sensor can be simply mounted on bridges, on the roofs of closed canals or on channel superstructures. The bed of the water should be as stable as possible in order to warrant consistent measurement. A visible swell must be evident on the surface of the water.

 

MEASURING PRINCIPLE

The non-contact radar technology determines the water surface flow velocity using the Doppler frequency shift method and furthermore, the water level is established by a travel time measurement. With a known cross section profile the discharge Q of the water can then be calculated on the basis of the continuity equation: Q = vm · A (h)
