The flowmeter technology employed by our FMU series is called “Transit-time” ultrasonic technology. It is also called “time-of-flight” or “time-difference” ultrasonic technology. In this technology, one of the keys to the precision performance is its transmission and reception technology. Transit-time provides an innovative direct ultrasonic transmission technique that ensures reliable and accurate signal detection for a wide range of processes.
