Abstract
A pressure transmitter is coupled directly to an industry standard flange adapter union having a standard bolt hole spacing. Small diameter isolator diaphragms are positioned on the transmitter housing at locations so that the industry standard flange adapter union which couple fluid pressure sources to act on the isolator diaphragms without an intermediate large flange or manifold as is presently required and using the fasteners for the adapter union to complete the coupling. The smaller isolaters fit within the bolt hole spacing of the industry standard adapter union.
