ABSTRACT:
A differential fluid pressure assembly (10) has an inner differential fluid pressure gauge (14) enclosed by an outer fluid-tight housing (12). A low pressure fluid inlet (34) is in fluid communication with the space (32) defined by the outer housing (12). A high pressure fluid inlet (38) extends through the outer housing (12) and is in fluid communication with a bourdon tube (44) within the differential pressure gauge (14). Low pressure fluid inlet (34) is connected to a low pressure line (36) extending to a low pressure fluid source. High pressure fluid inlet (38) is connected to a high pressure fluid line (40) extending to a high pressure fluid source for measurement of the differential fluid pressure between a low pressure source and a high pressure source.
