The RQ-24 sensor enables the continual measurement of flow
velocity and level and automatically calculates the discharge
quantity of surface waters. Based on the non-contact measurement
principle of Doppler radar technology and time delay measurement,
the quality of the RQ-24’s measurements and its flexibility of
deployment make it unique in its sector.
