摘要： PROBLEM TO BE SOLVED: To provide an integrating flowmeter which can obtain accurately an integrated flow rate of fluid passing a specified channel, without depending on presence and absence of a pulsation state.
SOLUTION: The integrating flowmeter is provided with a thermal flow sensor for measuring an instantaneous flow rate of the fluid passing the specified channel, a flow rate measure which integrates the instantaneous flow rate measured by the flow sensor, outputs a unit flow rate signal when the integrated value reaches a prescribed unit flow rate, and resets the integrated value, and a flow rate integrating means which counts the unit flow rate signal output from the flow rate measure, and obtains an integrated flow rate of the fluid passing the specified channel. The integrating flow meter is provided especially with a pulsation detecting means for detecting a pulsation state of the fluid in the channel, and a flow rate measure changing means which changes largely and sets the unit flow rate turning to interpretation criteria of an integrated value in the flow rate measure, when a pulsation is detected by the pulsation detecting means.

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.

When the valve element 2 has continued a fully closed state for a prescribed period Tth or longer, or at every timing of the prescribed period Tth, the valve element 2 is moved from a fully closed state to a prescribed position to make a half-open state, and it is then returned to the fully closed state. Alternatively, the valve element 2 is moved from a fully open state to a prescribed position to make the fully closed state, and then it is returned to the fully open state.
