MOUNTING SYSTEM FOR PRESSURE TRANSMITTERS

摘要

A mounting plate is disclosed that is adapted to be positioned between a main flow line and at least two differential pressure transmitters, to place the two differential pressure transmitters in fluid communication with a pair of pipeline taps on opposite sides of a flow reducing orifice plate in the main flow line is disclose. The mounting plate includes a plate-like body generally rectangular in cross section along its longitudinal axis and longer than it is wide along its transverse axis. The plate-like body includes a pair of ports that extend through the body and are in fluid communication with the pair of pressure taps with the longitudinal axis of the body parallel to the main flow line. A plurality of passageways or bores extend into the body to connect the ports to various combinations of pressure transmitters. One or more mounting holes for the transmitters are on a line that intersects the longitudinal axis of the body at an angle to allow some of the passageways or bores to be drilled straight and parallel to the longitudinal axis of the body between the mounting holes. In another embodiment, a sub plate is used to supply pressure to a third pressure transmitter. In another embodiment, a plate-like adapter, as well as the sub plate, is used to mount four differential transmitters or three differential pressure transmitters and a static pressure transmitter.
