Ultrasonic flow measurement
with the transit time difference measurement
Ultrasonic flowmeters measure the velocity of a flowing medium using acoustic waves. This flow measurement method offers several advantages. For example, it is largely independent of the properties of the media used, such as electrical conductivity, density, temperature and viscosity. The absence of moving mechanical parts reduces maintenance requirements. For ultrasonic flow measurement with transit time difference measurement, however, the medium must be as homogeneous as possible and have only a low solid and gas content.
