ABSTRACT:
An apparatus is provided for detecting the pressure of a fluid. The device includes a device for detecting the pressure of a fluid comprising (a) a housing; (b) a first conduit disposed within the housing, having an open inlet end, and an outlet end; (c) a second conduit disposed within the housing having an inlet end and an open outlet end; and (d) a pressure detector disposed within the housing in abutment with the outlet end of the first conduit and the inlet end of the second conduit, such that the pressure detector is in direct operative contact with a fluid flowing within the first and second conduits. Typically, the pressure detector is a pressure transducer. Preferably, the pressure transducer is located within the body, such that the first conduit is disposed at an angle with respect to the pressure sensitive surface of the transducer, the angle being between about 50.degree. and about 75.degree., most preferably between about 65.degree. and about 70.degree.. It is also preferable that the fluid is a degassed liquid such as degassed water.
