ABSTRACT:
In a fluidic flowmeter for measuring the flowrate higher than the preset flowrate by use of a fluidic element and for measuring the flowrate lower than the present flowrate by use of a flow sensor inserted into the nozzle portion, the present invention relates to the fluidic flowmeter that has an abnormality judging circuit for judging an abnormality and issuing a warning signal and also zero point and gain correcting circuits when operating the flowrate on the basis for the signal being output from the flow sensor in the case that the flowrate signal higher than the preset flowrate is to be input only from the flow sensor side and in the case that the flowrate signal higher than the preset flowrate is to be input only from the flow sensor side and in the event that the flowrate signal lower than the preset flowrate is to be input only from the fluidic element side.
