Abstract

A manifold includes a body having generally planar inlet surface. The inlet surface includes a first inlet and a second inlet adapted for coupling to a pressurized process fluid. An outlet surface on the manifold is adapted for coupling to a co-planar transmitter and is at angle relative to the inlet surface. The manifold includes an equalizing valve surface opposite the outlet surface, and a perimeter therebetween. The outlet surface includes first and second outlets in fluid communication with the first and second inlets, respectively.

Claims

1. A manifold, comprising:

a generally planar inlet surface;

a first inlet in the inlet surface;

a second inlet in the inlet surface, the second inlet spaced apart from the first inlet;

a generally planar outlet surface arranged substantially perpendicular to the generally planar inlet surface;

a first outlet in the outlet surface;

a second outlet in the outlet surface;

a first passageway extending between the first inlet and the first outlet;

a second passageway extending between the second inlet and the second outlet; and

a plurality of mounting holes on the outlet surface.

2. The manifold of claim 1 wherein the first inlet and the second inlet are threaded.

3. The manifold of claim 1 including a first valve configured to selectively block the first passageway and a second valve configured to selectively block the second passageway.

4. The manifold of claim 1 including a first body member defining the first generally planar inlet surface and second body member defining the second generally planar inlet surface.

5. The manifold of claim 4 including a third body member and wherein the first, second and third body members are arranged in an H-configuration.

6. The manifold of claim 1 including an equalization passageway between the first passageway and the second passageway.

7. The manifold of claim 6 including a valve configured to selectively close the equalization passage.

8. The manifold of claim 1 including a first equalization passageway coupled to the first passageway, a second equalization passageway coupled to the second passageway and an equalization chamber selectively coupling the first equalization passageway to the second equalization passageway.

9. The manifold of claim 8 including an equalization valve in the equalization chamber.

10. The manifold of claim 1 including a vent coupled to first and second passageways.

11. The manifold of claim 1 wherein spacing between the first and second outlets is in accordance with DIN spacing requirements.

12. The manifold of claim 1 wherein spacing between the first and second outlets is about 5.4 centimeters.

13. The manifold of claim 1 wherein spacing between the first and second inlets is about 5.4 centimeters.

14. A manifold for use with a pressure sensing transmitter for measuring pressure of a process fluid, the manifold comprising:

a manifold body including a first side member having an inlet surface and a cross member having an outlet surface, the first side member and cross member disposed at substantially a 90°

angle relative to each other;

first and second inlets on the first side member adapted for coupling to the process fluid;

first and second outlets on the outlet surface adapted for coupling to the pressure sensing transmitter;

passageways in the manifold body extending between and connecting the inlets and outlets; and

wherein the plane of the inlet surface is not parallel with the plane of the outlet surface.

15. The manifold of claim 14 further comprising:

the outlet surface of the cross member adapted to directly mount to the pressure sensing transmitter;

wherein the cross member comprises at least one valve stem;

an opposing surface on an opposing portion coupled to the cross portion, opposite the inlet surface, wherein the inlet surface, cross portion and opposing surface form an “

H”

configuration.

16. The manifold of claim 14 wherein the plane of the inlet surface is substantially perpendicular to the plane of the outlet surface.

17. The manifold of claim 14 including a first equalization passageway coupled to the first outlet, a second equalization passageway coupled to the second outlet and an equalization chamber selectively coupling the first equalization passageway with the second equalization passageway.

18. The manifold of claim 14 and further comprising:

a first blocking chamber in a first blocking chamber plane and disposed within the cross-member wherein the first blocking chamber is in direct communication with the first inlet and first outlet; and

a second blocking chamber in a second blocking chamber plane and disposed within the cross-member wherein the second blocking chamber is in direct communication with the second inlet and second outlet.
