Ultrasonic fluid meter comprising pressure sensor

An ultrasonic fluid meter (1) comprising: an ultrasonic measurement device (6); a valve (12) comprising a movable member (14); a position sensor (15) configured to measure a current position of the movable member; a pressure sensor (16) arranged to measure a pressure of the fluid in the conduit; a processing unit (5) arranged to evaluate the current flow rate as a function of the current position of the movable member, the pressure of the fluid at the current flow rate, and the pressure of the fluid at zero flow rate, if the current position of the movable member is such that the current flow rate cannot be measured by the ultrasonic measurement device. 一种超声流体表(1)，包括：超声测量设备(6)；阀(12)，包括可移动构件(14)；位置传感器(15)，被配置成测量可移动构件的当前位置；压力传感器(16)，被布置成测量在管道中的流体的压力；处理单元(5)，被布置成在可移动构件的当前位置使得当前流速不能被超声测量设备测量的情况下根据可移动构件的当前位置、流体在当前流速下的压力、以及流体在零流速下的压力来评估当前流速。
