Abstract
A temperature compensator for gas meters is comprised of two serially connected bi-metallic elements extending between the tangent post and the drive shaft from the flow responsive element. The bimetallic elements are reversely oriented whereby each element responds to a given temperature change to produce movement in the same direction as the other with respect to the axis of the drive shaft.
