KOBOLD DUK Series compact ultrasonic flowmeters are used for measuring, monitoring, and batching of low viscosity (water-based) fluids. These compact ultrasonic flowmeters with no moving parts work on the principle of run-time difference. Ultrasonic waves in the media are influenced by the rate of flow. It features two sensors mounted opposite one another in the pipeline, which function simultaneously as transmitter and receiver of ultrasonic signals. If no flow is present, the run-times of both signals are identical. If the media is flowing, the run-time of the signal against the flow will be longer than the signal with the flow. This run-time difference, determined by the KOBOLD DUK Series compact ultrasonic flowmeter’s microprocessor, is proportional to flow rate.
