The KUF100 ultrasonic flowmeter operates using the time difference method. It sends and receives ultrasonic signals through the fluid and calculates the flow rate by measuring the difference in the propagation time of these signals in the downstream and upstream directions. This method enables precise measurement of fluids with suspended particles or bubbles and is not influenced by the fluid's conductivity.
