Patent ID: 11821773

Abstract:
An ultrasonic fluid meter comprises a conduit (4) in which a fluid can flow, an ultrasonic measurement device (6) for evaluating a current flow rate of the fluid, a valve (12) comprising a moving member (14) for controlling the current flow rate of the fluid, a position sensor (15) for measuring a current position of the moving member (14), a first pressure sensor (16) for measuring a first pressure of the fluid upstream of the valve (12), and a second pressure sensor (17) for measuring a second pressure of the fluid downstream of the valve (12), and a processing circuit (5) for evaluating the current flow rate as a function of the current position of the moving member (14) and of a pressure value representative of a difference between the second pressure and the first pressure, if the current flow rate cannot be measured by the ultrasonic measurement device (6).
