Abstract
An ultrasonic fluid meter comprising a conduit in which a fluid can flow, an ultrasonic measuring device comprising an upstream transducer and a downstream transducer for evaluating a current flow rate, a valve comprising a movable member for controlling the current flow rate, a position sensor for measuring a current position of the movable member, a processing circuit for, if the current position of the movable member is such that the current flow rate cannot be measured by the ultrasonic measuring device, evaluating the current flow rate as a function of the current position of the movable member and of a pressure value which is representative of a difference between a second pressure of the fluid downstream of the valve, evaluated via an impedance of the downstream transducer, and a first pressure of the fluid upstream of the valve, evaluated via an impedance of the upstream transducer.
