The new KOBOLD type DUK flow meters are used for the measurement, monitoring, metering and dosing of low viscosity fluids.
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 ultrasound signals.
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 microprocessor, is proportional to the speed of flow.
