KOBOLD Instruments, Inc. DUK - Compact Ultrasonic Flowmeter

Product Features Suitable for many water-like liquids with max. 1% solids High turndown ratio of 250 to 1 Very small pressure loss Highly Repeatable Measurement independent of density and temperature changes The KOBOLD model DUK flowmeters are used for measuring, monitoring, and batching of low viscosity (water-like) fluids. The devices work on the principle of run-time difference. Ultrasonic waves in the media are influenced by the rate of flow. Two sensors mounted opposite one another in the pipeline 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 a microprocessor, is proportional to the rate of flow.
