Abstract
An ultrasonic fluid meter includes an ultrasonic measuring device, a valve comprising a movable member, a position sensor configured to measure the current position of the movable member, a pressure sensor arranged to measure the pressure of the fluid in the conduit; and a processing circuit arranged, if the current position of the movable member is such that the current flow rate cannot be measured by the ultrasonic measurement device, to evaluate the current flow rate as a function of the current position of the movable member, of the pressure of the fluid to the current flow rate, and of the pressure of the fluid at zero flow rate.
