Abstract

A dry gas meter includes a unitary core which functions as the meter casing and defines the inner sides of two gas chambers, a valve gear chamber, an index housing and multiple gasways. A central partition of the core has angled wall portions which provide dished sides for the gas chambers. The gas chambers are further defined by diaphragm carrying pan covers. These pan covers and upper and lower covers complete the body of the meter. Between the angled wall portions, gasways extend from a gas inlet formed in the lower cover to the interior of a valve gear chamber.
