The adoption of a variable cross-sectional area venturi achieves both low pressure loss and a wide flow range!
The "VAV-EGF6" is a venturi-type flow meter that directly measures the exhaust flow rate of an engine. The position of the movable core is adjusted according to changes in flow rate, and the cross-sectional area of the venturi throat is controlled at high speed. This variable venturi mechanism achieves a wide dynamic range with a ratio of minimum measurable flow rate to rated flow rate (accuracy guarantee range) of approximately 30 times, while maintaining a total pressure loss of less than 0.5 kPa. 【Features】 ■ Variable cross-sectional area venturi that achieves low pressure loss and a wide flow range ■ Pulsation damping device (surge tube) that reduces measurement errors caused by pulsation ■ PC software for modal mass measurement ■ Flow calibration and high-temperature flow verification tests conducted *For more details, please refer to the PDF document or feel free to contact us.
