确实有公司有使用这种进行流量计确认(或流速确认),上虞新京制药的检查报告中有提及。你可以参考。不知道LZ现在是否有购买??什么牌子??使用得怎么?

The GE Panametrics Transport PT878 Portable Ultrasonic Liquid Flowmeter is a highly versatile, self-contained, portable transit-time system with options and accessories to meet all your liquid flow measurement needs. The Transport PT878's compact size, lightweight, rechargeable internal battery pack; and universal power supply charger make it the ideal go-anywhere flow meter.
The TransPort PT878’s patented Correlation Transit-Time™ digital signal processing (DSP) technique greatly increases its signal-to-noise ratio for accurate, drift-free flow measurement in liquids that contain a second phase of entrained solids or gas bubbles. The Panametrics PT878 operates in these and other difficult applications where conventional transit time flow meters fail.
The TransPort PT878 flow meter also accurately measures flow rate in perfectly clean liquids containing no “scatterers,” where Doppler flow meters cannot work. The GE Panametrics PT878 is suited for all standard transit time applications, plus many that would prevent other transit time flow meters from working.(注意有一种Doppler ultrasonic flowmeter需要水中有一定的颗粒度或者气泡,所以不适用纯水的测定)
