For use in connecting a measuring instrument across a pipeline portion having an orifice therein to create a pressure drop whereby static and differential pressure signals are formed, a unitized connector apparatus is set forth in the preferred and illustrated embodiment and includes an elongate rectangular body having a lengthwise axial passage drilled therethrough. Additional passages intersect the long passage at the ends, and suitable valve means are included near the ends thereof. The structure is a unitized structure adaptable for quick and prompt installation with a minimum of connections made to the measuring instrument. Moreover, the structure is roddable, that is, the passages can be easily cleaned by means of a rod inserted therethrough.
