This flow metre uses the propagation time difference method, whose ultrasonic propagation time differs depending on the rate of liquid flow in a pipe.
Due to the ability to measure from outside of a pipe, it is possible to measure various types of liquid without worrying about corrosion.
We have hand-held types that are appropriate for examining and inspecting the flow of various places in addition to wall-mount types that are stable for permanent standing.
