Flow sensor assembly with integral bypass channel

摘要

Abstract 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). to) 8F '00 7, to LO
