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.
