ABSTRACT:
An improved industrial meter housing assembly includes a compactly designed metal housing having a central trefoil shaped chamber and minimal length inlet and outlet ports in fluid communication with the chamber with the ports ending at inlet and outlet port faces on the housing outer surface oriented 90.degree.degrees from each other and 45.degree.degrees to the vertical with the housing in its upright position. The housing may be installed as original equipment in an industrial environment having upstream pipe connections provided to match those input and output port faces. However, the compactness of the housing may be utilized together with a pair of installations-specific inlet and outlet runner pipes to enable the combination meter housing/runners to be substituted for any existing original equipment industrial meter. Additionally, the inlet and outlet ports of the compact meter housing are shaped to match the width and radius (area) of the displacement rotors, and the inlet and outlet runner pipe passageways are shaped to provide a smooth transition from the circular cross-section inlet and outlet fluid transmission pipes to the generally rectangular inlet and outlet port configurations. Further, the short inlet and outlet ports in the housing are curved to direct the fluid flow in a less turbulent manner to and from the displacement rotors rather than directing the fluid flow to and from the blocking rotor or between the blocking rotor and the displacement rotors.
