Seba LogCom-QUniLogCom-Q Ultrasound Doppler

The flow rate is measured in up to 18 layers by an ultrasonic

flow velocity sensor using the pulse Doppler method. An average

flow velocity in the detection area of the sound beam is

then calculated from these values. The total flow at the measurement

cross-section is determined from the average flow

velocity, the water level and the channel profile information.

This measurement method is suitable for free flowing water

and backed up water. The data for water level, average flow

velocity and calculated flow rate are stored locally in a batteryoperated

data logger and transmitted via mobile network to a

central station
