Temperature compensated gas meters.

摘要

A temperature compensator for gas meters is comprised of two serially connected bi-metallic elements (62, 64) extending between the tangent post (30) and the drive shaft (40) from the flow responsive element. The bi-metallic elements (62. 64) 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 (40).
