RQ SERİES
The RQ-30 is a sensor for continuous discharge measurement of
rivers, open channels and canals with known cross-section profile.
The sensor uses innovative radar technology to measure velocity,
water level and discharge. It enables reliable, non-contact
measurement without the need for structural work in the water.
Non-contact, maintenance free measurement system
No structural work is necessary 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 +/- 15 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
Automatic angle measurement
Optional (RQ-30a): analogue outputs from 4 to 20 mA
SQ SERİES
The radar sensors of the SQ series continuosly measure
the discharge(flow) volume of sewer
systems, ducts, semi-filled pipes and other
technical channels in the fields of wastewater and industrial
effluents. Due to the contact-free measurement deposits and other solids in the water do not harm the sensor. This is especially advantageous for the measurement of wastewater. The compact design allows an installation in manholes or in sewage systems.
