FUNCTION
Our CU series flowmeters use the transit time measurement principle, which measures the time it takes for an ultrasonic signal to travel from the upstream sensor to the downstream sensor through a cross-sectional pipe.
Two-time measurements are compared. Both directions will experience the same transit time if there is no flow. With flux, the signal moves faster with flux and slower with flux.
The measured time difference is directly dependent on the velocity of the fluid through the pipe and is a suitable value for measuring and monitoring the flow of liquids and gases. As the ultrasonic signal travels from one sensor (transmitter) to the other sensor (receiver) through the pipe, only a minimal amount of air bubbles or solids may be present inside the pipe. High-frequency sound will be attenuated if there is a large amount of suspended solids in the pipe, so the signal will be insufficient to reach the other side of the pipe.
BENEFITS
Ultrasonic flowmeters are non-intrusive devices well suited for rapid flow measurement. As well as being very versatile, economical, and easy to install, it is also easy to clean. It accepts liquids with minimal suspended solids and is suitable for utility, process and energy metering applications.
