Abstract
A pressure monitoring assembly includes an isolation valve assembly and a differential pressure sensor assembly. The rigid manifold has two pressure inlet ports which each communicate with respective pressure outlet ports through isolation valves. An equalization passage and valve connect the two pressure lines. The pressure sensor assembly is sized to mate directly with the monolithic manifold by having sensor inlet ports that line up with the pressure outlet ports. Pressure tight attachments releasably secure the pressure sensor assembly to the manifold, but are rigid to support the weight of the pressure sensor assembly. No bleeding valves are necessary. Orientation and the positioning and construction of the manifold effectively reduce the amount of heat transfer between the pressure lines and the pressure sensor(s).
