<p>PROBLEM TO BE SOLVED: To provide a gas flowmeter for hospital in which the flow rate can be adjusted in a short time. SOLUTION: This gas flowmeter is provided with a flow rate calculation means 39a-1 for calculating an instantaneous value of the flow rate by measuring the flow rate in a normal mode by a first sampling period; a display means 13 for displaying the instantaneous value of the flow rate calculated by the calculation means 39a-1; a mode changing means 15 for changing the normal mode to an adjustment mode; and a control means 39a-3 for controlling the calculation means 39a-1 running in the normal mode for a predetermined period to calculate the instantaneous value of the flow rate by measuring the flow rate adjusted by a flow rate adjusting means in the adjustment mode based on the operation of the changing means 15 by a second sampling period shorter than the first sampling period.</p> |
