Abstract:
A fluid pressure detector comprising at least one differential pressure detector member;said differential pressure detector member comprising:(a) a pair of tubular members of an identical configuration, each of said tubular members having a flattened shape having opposed narrow side walls and opposed wide side walls, and at least one pressure-measuring port being formed through one of said opposed narrow side walls; and(b) a pair of plug members mounted on and closing opposite open ends of each of said tubular members, respectively, one of said pair of plug members having a pressure outlet port;wherein said pressure-measuring port in one of said pair of tubular members is directed toward an upstream side with respect to a direction of flow of fluid to be measured, thereby forming a total pressure-measuring port, while said pressure-measuring port in the other tubular member is directed toward a downstream side, thereby forming a static pressure-measuring port, and said pressure outlet port in said plug member, mounted on said one tubular member, serves as a total pressure outlet port while said pressure outlet port in said plug member, mounted on said other tubular member, serves as a static pressure outlet port.
