    Abstract: A control means configured to perform flow rate control in which the control means outputs a control signal to a flow control valve to control a valve opening such that a measured flow rate of gas measured by a flow meter matches a set flow rate adjusts intensity of the control signal such that an absolute value of a change amount of the valve opening becomes larger as measured temperature of the gas measured by a thermometer becomes further higher than reference temperature, while the absolute value of the change amount of the valve opening becomes smaller as the measured temperature becomes further lower than the reference temperature. Thereby, change of response time on changing the valve opening of the flow control valve due to the difference between the measured temperature of the gas and the reference temperature can be reduced.

    Abstract: A mechanical computer for a compensated meter counter assembly for a gas meter includes a one-way clutch with an input hub drivingly releasable and connectable to an output shaft for driving a register. A computer arm carried by the input hub oscillates along a specified arc about the axis of the hub between an initial position and a travel limiting cam surface positioned in response to temperature changes. An adjustably settable connection is provided between the arm and the hub for selectively pivoting said arm about said hub to position the outer end of the arm in a selectively set angular position relative to said hub and along the arc. In this position the outer end of the arm is held so as to precisely register with the initial position of the arc at the start of each oscillation.
