Working principle

The flowmeter model CU100 is an electronic device based on the transmission of ultrasonic signals through a pipe where liquid flows. This working principle is called “transit time”. Two ultrasonic transducers, acting alternately as transmitter-receiver and properly installed on a pipe, send an ultrasonic signal, first in one direction (A→B) , then in reverse (B→A). A digital processor measures both transit times. When flow rate is zero, these times (A→B and B→A) are the same, but when there is a flow at a specific speed, the times for coming and going are different (A→B decreases, while B→A increases). The difference between these times is proportional to liquid speed inside the pipe. An electronic circuit based on digital signal processing converts this difference in transit time into a flow rate value.
