The adapter (10) according to the invention comprises an attachment connector (11), an attachment connector (12) and an attachment connector (13). A respective free connector end (11+, 12+ or 13+ respectively) of each of the attachment connectors (11, 12, 13) is designed for being connected to a line end of in each case one (other) fluid line. Furthermore, the adapter (10) has two mutually separate, tubular flow ducts (10-I, 10-II) which are designed in each case for guiding fluid flowing in and flowing out again, of which flow ducts one flow duct (10-I) extends from a flow opening (12a) located in the free connector end (12+) of the attachment connector (12) to a flow opening (11a) located in the free connector end (11+) of the attachment connector (11), and one flow duct (10-II) extends from a flow opening (13a) located in the free connector end (13+) of the attachment connector (13) to a flow opening (11b) located in the free connector end (11+). Furthermore, the adapter (10) comprises a projection (14) which adjoins a region, located between the flow openings (11a, 11b), of the free connector end (11+) and which extends from same connector ends (11+) with a length (l 14 ) to a free projection end (14+) remote therefrom. A fluid line system formed by means of the adapter (10) furthermore comprises a fluid line (100) with a lumen encased by a wall, which lumen extends from a flow opening (100a) located in a line end (100+) of the fluid line (100) both to a flow opening (100b) located in a line end (100#) of same fluid line (100) and to a flow opening (100c) located, spaced apart from same flow opening (100b), in the line end (100#). The fluid line (100) may be connected by means of its line end (100+) to the attachment connector (11) of the adapter (10) in such a way that the projection (14) projects into the lumen of the fluid line (100) so as to form two tubular chambers of the fluid line (100), which tubular chambers are separated from one another by the projection (14) and are each designed for guiding fluid flowing through.

Systems, apparatus and methods are disclosed for coupling an averaging pitot tube (APT) primary element to a process pipe (108). A mounting assembly (112) mounts the APT primary element (120) to the process pipe (108) such that a length of the APT primary element (120) extending into the process pipe (108) is adjustable to accommodate different sized process pipe (108) diameters. The mounting assembly (112) includes a weld coupling (305) coupled to the process pipe (108) over an opening in the process pipe and having the APT primary element extending therethrough into the process pipe. An extension pipe nipple (310) is connected to the weld coupling (305) and has the APT primary element (120) extending therethrough such that a transition between a neck section (304) and a sensor section (303) of the APT primary element (120) is positioned inside the extension pipe nipple (310). A union component (315), a ferrule (320), and a cap (325) keep the APT primary element (120) in the mounted position and form a process seal.

摘要:
Flow sensor assemblies (38) having increased flow range capabilities are disclosed. In one illustrative embodiment, a flow sensor assembly (38) includes a housing (40) with an inlet (88) flow port, an outlet flow port, a fluid channel (12) extending between the inlet flow port (88) and the outlet flow port (90), and a bypass channel (62) having a pair of taps (64) fluidly connected to the fluid channel (12) at separate locations. A flow sensor (10) for sensing a measure related to a flow rate of a fluid flowing through the fluid channel (12) can positioned in the bypass channel (62). A pressure differential between the two taps (64) of the bypass channel (62) can drive a fraction of a fluid flowing through the fluid channel (12) through the bypass channel (62). The flow sensor assembly (38) may be configured to achieve, control, and/or balance a desired fraction of fluid flow (14) through the bypass channel (62) and past the flow sensor (10).
