Manifold valve and pressure transducer assembly
First Claim
1. A method for assembling a pressure monitoring assembly comprising:
- (A) providing a manifold valve assembly comprising;
(1) a rigid manifold body having a first pressure inlet port and a second pressure inlet port, and a first pressure outlet port and a second pressure outlet port, wherein said first pressure inlet port and said first pressure outlet port are in parallel relationship with said second pressure inlet port and said second pressure outlet port, and wherein said outlet ports have a connection to a manifold body flange;
(2) a first isolation valve in a fluid passageway between said first pressure inlet port and said first pressure outlet port, wherein said first isolation valve can be adjusted between an open position in which said first pressure inlet port and said first pressure outlet port are in communication through said fluid passageway, and a closed position in which said communication through said fluid passageway is stopped; and
(3) a second isolation valve in said fluid passageway between said second pressure inlet port and said second pressure outlet port, wherein said second isolation value can be adjusted between an open position in which said second pressure inlet port and said second pressure outlet port are in communication through said fluid passageway and a closed position in which said communication through said fluid passageway is stopped;
(B) providing a pressure transducer assembly comprising;
(1) a transducer mounting plate for attaching transducers;
(2) a first transducer rigidly secured to a first transducer port in said transducer mounting plate;
(3) a second transducer rigidly secured to a second transducer port in said transducer mounting plate in parallel relationship with said first transducer, wherein the spacing between said first transducer and said second transducer equals the outlet port spacing of said rigid manifold valve body; and
(4) a pressure transducer housing having sides defining an enclosure which supports said transducer mounting plate and provides threaded holes for attachment to said manifold body flange;
(C) inserting said transducer mounting plate into the mating recess of said pressure transducer housing such that said transducer mounting plate extends beyond said pressure transducer housing; and
(D) aligning said manifold valve assembly with said pressure transducer assembly such that the bolt holes in the manifold valve body flange align with said threaded holes in said pressure transducer housing; and
(E) securing said pressure transducer assembly to said manifold valve assembly in a pressure tight and releasable manner with the use of bolts.

Abstract
An assembly for measuring differential pressures includes a manifold valve and pressure transducer assembly including two pressure transducers. The manifold valve includes two pressure inlet ports and two pressure outlet ports that communicate through the manifold'"'"'s isolation valves. An equalization valve connects the two pressure lines. Mating flanges on the manifold valve and pressure transducer assembly are bolted together to form a pressure tight seal between the manifold valve outlet ports and the pressure transducer assembly inlet ports. The pressure transducer assembly also includes a mounting plate for supporting the pressure transducers. The transducers generate an electrical signal corresponding to inlet pressure. Signals from pressure transducers and an optional thermistor for each are wired to an electrical connector mounted on the side of the assembly. The signals are electronically compared with an external signal processing circuit that outputs a representative signal of the differential pressure.
