摘要： PROBLEM TO BE SOLVED: To provide a flowmeter capable of easily and accurately determining an integrated quantity of flow without being affected by fluid fluctuations caused by disruptions in pressure balance, biased temperature distributions in piping, etc.
SOLUTION: The flowmeter includes a flow sensor capable of measuring the instantaneous quantity of flow of forward and backward flows of a fluid; a smoothing means for smoothing the measured instantaneous quantity of flow; an integrating counter for integrating and outputting the smoothed quantity of flow; a determination means for determining the presence or absence of fluctuations of the fluid by monitoring the smoothed quantity of flow; an auxiliary counter for integrating the smoothed quantity of flow instead of the integrating counter while the determination means is determining fluctuations and when it determines the presence of a fluctuating flow; and a control means for restarting the integration of the smoothed quantity of flow by the integrating counter by adding the integrated quantity of flow by the auxiliary counter to the integrating counter when the determination means determines the presence of a normal flow.

摘要： PROBLEM TO BE SOLVED: To provide a flowmeter provided with a degradation diagnostic function of flow sensors capable of easily and reliably detecting degradation of characteristics of flow sensors.
SOLUTION: It is judged that a plurality of high-speed flow sensors or a plurality of low-speed flow sensors can have degraded when output values of the plurality of high-speed flow sensors or output values of the plurality of low-speed flow sensors are different from one another. In the case that flow quantity values determined on the basis of low-speed flow sensors or high-speed flow sensors which are not used for the measurement of the quantity of flow are each greater than a first flow quantity threshold value, it is determined whether a flow quantity value determined on the basis of each flow sensor judged as that it can have degraded exceeds the first flow quantity threshold value or not to specify a degraded flow sensor.
