摘要:
A fluid treatment system comprises a housing defining a fluid flow channel through which fluid is flowable in a fluid flow direction from an inlet to an outlet of the housing, a first fluid treatment device positioned within the fluid flow channel between the inlet and outlet, a second fluid treatment device positioned within the fluid flow channel between the first fluid treatment device and the outlet, and at least one sensor module comprising a sensor probe positioned within the fluid flow channel between the first and second fluid treatment devices. The sensor probe comprises a plurality of hollow arms extending radially outward from a radially inward portion to a radially outward portion of the fluid flow channel. Each of the arms comprises apertures facing a direction substantially opposite the fluid flow direction, the apertures being in fluid receiving communication with a sample portion of fluid flowing through the fluid flow channel. The sensor module further comprises at least one sensor communicable in sensing communication with fluid received through the apertures.

According to one embodiment, a sensor module (100) includes a sensor probe (120) that has at least two arms (122) coupled together at a central location (186) with each of the at least two arms extending radially outwardly away from the central location. Each of the at least two arms includes one of a plurality of openings (126) and an elongate opening (530) extending radially along the arm. The at least two arms define fluid flow channels (190) therein. The sensor module also includes at least one extractor (130) coupled to the probe. The at least one extractor includes a fluid flow channel (192) that is communicable in fluid receiving communication with fluid flowing through the fluid flow channel of at least one of the at least two arms. Further, the sensor module includes at least one sensor (142) that is communicable in fluid sensing communication with fluid flowing through the at least one extractor.

摘要:
A high pressure fuel pump with parallel cooling fuel flow is disclosed wherein a fuel pump barrel having a substantially cylindrical plunger bore with an annular drain groove is provided. A first fuel path is provided that fluidically couples a fuel supply to an annular cooling ring formed on the outer surface of the barrel. The first fuel path further fluidically couples the annular cooling ring to a storage tank via an exit passage. A second, parallel fuel path is provided that fluidically couples the first fuel path to the drain groove, and further includes a drain passage fluidically coupled to the drain groove and the first fuel path via the storage tank.
