MOUNTING MEANS FOR FLUID PRESSURE TRANSMITTERS

摘要

A mounting plate (20) is positioned between a manifold (18) and a pair of fluid pressure transmitters including a differential pressure transmitter (22) and a gauge pressure transmitter (24). The fluid pressure from high and low pressure taps or lines (14, 16) placed on opposite sides of a flow restriction (12) of a main flow line (10) is measured and transmitted to a remote location by the transmitters (22, 24). The mounting plate (20) has low and high pressure ports (62, 64) for differential pressure transmitter (22) and a low pressure port (66) for a gauge pressure transmitter (24). A connecting fluid passage (68) connects the low pressure ports (62, 66) and a block valve (80) is movable between open and closed positions to permit or block fluid communication between the ports (62, 66) and fluid communication between the transmitters (22, 24). One pair of ports (66, 76) are arranged in symmetrical relation to the other pair of ports (62, 64) to permit the mounting plate (20) to be utilized with the gauge pressure transmitter (24) for measurement of either a low pressure or a high pressure.
