CONTINUOUS INTEGRATOR CONTROL LINKAGE Abstract of the Disclosure A variable ratio drive transmission driven by a fluid meter has means to vary the output to a counter in accordance with variations in both the pressure and temperature of the fluid and is comprised of a rotatable disc the drive surface of which is in drive engagement with two wheel members, both of which are mounted for adjustment radially of the axis of rotation of the disc member. The drive surface of the disc is in a plane normal to its axis of rotation and is comprised of an elastomer having a high degree of recovery and a high degree of resistance to abrasion. The drive from the meter is through one of the wheel members the radial position of which is adjusted in accordance with variations in the temperature of the fluid being metered. The radial position of the other wheel member is adjusted in accordance with variations in the pressure of the fluid being metered and is drive connected to an output counter to indicate total volume of fluid flow through the meter corrected for both pressure and temperature. A flexiable connection is provided in the linkage between the temperature sensing element and the pressure sensing element and their respective wheel members to permit flexing of the sensing elements when the disc and wheel members are not in motion. Means is provided to adjust the temperature limits within which the apparatus will operate, the position of the fluid temperature versus accuracy curve of the apparatus, to adjust the linearity of the fluid pressure versus accuracy curve, and to adjust the position of the fluid pressure versus accuracy curve.
