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.
