摘要：

The use of a surface-acoustic-wave (SAW) device to measure the flow rate of liquids is described. A delay-line stabilized SAW oscillator heated to a suitable temperature above ambient is cooled by the flowing fluid. This results in a change in the oscillator frequency. The frequency of a 68-MHz oscillator operated at 9°C above ambient is found to vary by more than 40 kHz for variation in water flow rate from 0. to 0.8 ml/min. © 1990 IEEE
