Ultrasonic Flowmeter/-Monitor/-Counter/-Dosing Unit Model DUK :
The new KOBOLD type DUK flow meters are used for the
measurement, monitoring, metering and dosing of low vis-
The devices work on the principle of the difference in running
times. This is based on the fact that ultrasonic waves in a
medium are influenced by the speed of flow.
Two sensors mounted opposite one another in the pipeline
function simultaneously as transmitter and receiver of ultra-
If there is no flow, then the running times of both signals are
identical. If the medium is flowing, then the running time of the
signal against the flow is longer than that with the flow.
The running time difference, which is determined by a micro-
processor, is proportional to the speed of flow.
