Arrangements of transducers for ultrasonic flowmeters; Circuits for operating ultrasonic flowmeters

Introduced: January 2022

Full Title

Full titles differ between systems:

IPC:

Measuring the volume flow or mass flow of fluid or fluent solid material wherein the fluid passes through a meter in a continuous flow > by measuring frequency, phase shift or propagation time of electromagnetic or other waves, e.g. using ultrasonic flowmeters > Arrangements of transducers for ultrasonic flowmeters; Circuits for operating ultrasonic flowmeters

CPC:

Measuring the volume flow or mass flow of fluid or fluent solid material wherein the fluid passes through a meter in a continuous flow (measuring a proportion of the volume flow G01F5/00) > by measuring frequency, phase shift or propagation time of electromagnetic or other waves, e.g. using ultrasonic flowmeters > Arrangements of transducers for ultrasonic flowmeters; Circuits for operating ultrasonic flowmeters
