ULTRASONIC FLOWMETER

원문 (중국어)

The problem to be overcome by the present disclosure is to provide an ultrasonic flowmeter configured to cause an insignificant pressure drop and to be applicable to even a fluid having moisture which would produce condensation. An ultrasonic flowmeter includes: a measuring flow channel () having a rectangular cross section and configured to allow a fluid under measurement to flow therethrough; a partition plate () arranged to divide the measuring flow channel () along shorter sides thereof into multiple sections; a pair of ultrasonic transducers () arranged on one of the shorter sides of the measuring flow channel () to cause an ultrasonic wave to propagate across the measuring flow channel (); a measuring circuit () configured to perform an operation of having the ultrasonic wave transmitted from one of the pair of ultrasonic transducers () and received at the other of the pair of ultrasonic transducers (); and an arithmetic circuit () configured to perform arithmetic processing on signals received at the pair of ultrasonic transducers (). A downstream end () of the partition plate () is arranged to be substantially parallel to a downstream ultrasonic wave propagation path () in a region downstream of the downstream ultrasonic wave propagation path ().
