Ultrasonic flow meters, in which reflecting ultrasound off a flowing liquid leads to a Doppler shift (see Doppler effect) that is calibrated to provide the flow rate of the liquid, have important industrial applications and have also been used to measure arterial blood flow.
An ultrasonic flow meter is installed inside the vessel.
Blood flow rate was continuously monitored with an ultrasonic flow probe (Transonic Systems, Ithaca, NY).
Cardiac output (CO) was measured using an ultrasonic flow probe placed around the pulmonary artery trunk.
A comparison with transit time ultrasonic flow meter shows the advantage of proposed methodology.
Philips et al. compared thermodilution CO with surgically implanted ultrasonic flow probes in an ovine model [22].
COEPBF was compared to a reference method for CO, an ultrasonic flow probe around the pulmonary trunk.
In the end, parametric analysis of viscosity on wave propagation and ultrasonic flow meter is compressively investigated.
Ultrasonic flow meter with non-invasive no-moving-parts construction has good prospective application for space on-orbit fluid gauging.
Effect of input power on the cavitational activity has been investigated at different locations in the ultrasonic flow cell.
The present paper describes the efforts performed while qualifying a time-of-flight ultrasonic flow meter as a transfer standard.
