    DELIVERS HIGH REPEATABILITY AND LOW PRESSURE LOSS


    DUK flow meters are engineered to measure, monitor, meter, and batch low viscosity liquids with a maximum solid content of 1%. They are highly repeatable, feature a small pressure loss, and offer measurement independent of density and temperature changes. They also feature an exceptional turndown ratio of 250 to 1. Common applications include: machine building, automotive, robotics, cooling, and hot water.


    VERSATILE


    The DUK can be equipped with a switching output, a frequency output, or an analog output. In addition, a compact electronic can be selected that features a digital display, a switching output, and an analog output. Batching or totalizing electronics are also available. The meter electronic indicates the momentary flow rate in the first line of the display and the partial or total flow in the second line. A batching electronic can control simple filling tasks and similarly measures flow rates, total amounts, and filling amounts. The analog output and two relay outputs can be used for further processing of the signals.


    HOW THEY WORK


    The DUK operates 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 the ultrasonic signals. If there is no flow, the run times of both signals are identical. If the media is flowing, then the run time of the signal against the flow is longer than the signal with flow. The run time difference, which is determined by a microprocessor, is proportional to the rate of flow.


    SPECIFICATIONS


    The DUK is available in ranges from 0.02 to 5 GPM up to 0.6 to 160 GPM and is made of brass or 316 stainless steel. It delivers an accuracy of ± 0.7 % of the rate and ± 0.7 % of the full scale. Fittings are available in ½” to 3” NPT. The maximum temperature is 248 °F and the maximum pressure is 230 PSIG.
