ULTRA Vortexor detects the Karman vortex by measuring lags and leads in ultrasonic wave transmission time using two pairs of ultrasonic sensors. Thanks to dual ultrasonic sensors, the ULTRA Vortexor minimizes measurable flow rate and brings about redundancy. FEATURES . Ultrasonic sensing Karman vortexes are generated by a bluff body in the flowtube. The frequency of a Karman vortex is proportional to flow velocity. ULTRA Vortexor detects a Karman vortex by measuring lags and leads in ultrasonic wave transmission time using two pairs of ultrasonic sensors. Compared with a vortex flow meter with a piezoelectric sensor, the sensitivity of the ULTRA Vortexor is greater. Also the ULTRA Vortexor is not affected by piping vibration. . Dual ultrasonic sensors Ultrasonic wave transmission speed varies by temperature. Temperature may have a significant effect on the detection of Karman vortexes when using on ultrasonic sensor. The ULTRA Vortexor incorporates two ultrasonic sensors which cancel the effect of temperature. . Redundancy Even if one ultrasonic sensor fails, the second sensor maintains flow rate measurement. . Expand Minimum measurable flow rate The minimum measurable flow rate of a conventional vortex flow meter is 0.3m/s. Dual ultrasonic sensors bring about high sensitivity. ULTRA Vortexor improves the minimum measurable flow rate from 0.3m/s to 0.1m/s. APPLICATIONS ULTRA Vortexor measures flow in a wide variety of fluids. . pure water, ion exchange water, tap water. . organic solvent (ethylene, methanol, ethyl acetate, ethanol, toluene, etc.) . gasoline, kerosene, light oil, diesel oil. Kinetic viscosity should be less than 20 x 10-6 m2/s. 4 15 Specifications are subject to change without notice. “This product is designed for general industrial use.”
