ABSTRACT:
A flowmeter comprises an output cut-off circuit controlled by a command signal generated by a flow switch, wherein the flow switch generates a command signal switching on the transmission of an electrical signal representing the flow rate of media to an output terminal, when the flow rate of media being measured by the flowmeter is greater than a preset threshold value, and switches off the transmission of the electrical signal representing the flow rate of media to the output terminal, when the flow rate of media is less than the preset threshold value.
