IPC: G01F1/66
Filed: 1985-07-08
Abstract: PURPOSE:To measure accurately an air flow rate by detecting the propagation time of an ultrasonic pulse between ultrasonic wave transmitter receivers provided so that measurement lines cross the axis of piping at a certain angle, and finding a real mean heat flow velocity. CONSTITUTION:For example, the tow ultrasonic wave transmitter and receivers 10 and 20 are provided so that their measurement lines cross the axis of the piping 12 at the certain angle in some axial cross section.
