GAS FLOWMETER

摘要

PROBLEM TO BE SOLVED: To provide a gas flowmeter that enables stable flow measurement in a gas meter having an ultrasonic flow rate measuring unit and a flow channel part.SOLUTION: A gas flowmeter comprises: a device main unit 1 for air-tightly housing a fluid to be measured; an inlet pipe 4 for introducing the fluid to be measured into the device main unit 1; an outlet pipe 5 for discharging the fluid to be measured out of the device main unit 1; an ultrasonic flow rate measuring unit 9 connected to the outlet pipe 5 and calculating a flow rate of the fluid to be measured flowing inside; a connection pipe 7 connected to the outlet pipe 5; a flow channel member 10 connected to the connection pipe 7 and having a flow channel shape identical to that of the ultrasonic flow rate measuring unit 9; and a support member 11 for fixing the ultrasonic flow rate measuring unit 9 and the flow channel member 10.
