摘要： The present disclosure relates generally to flow sensors, and more particularly, to methods and devices for reducing variations in fluid flow across the flow sensor for increased accuracy and/or reliability. In one illustrative embodiment, a flow sensor assembly includes a housing with an inlet flow port and an outlet flow port. The housing defines a fluid channel extending between the inlet flow port and the outlet flow port, with a flow sensor positioned in the housing and exposed to the fluid channel. The flow sensor is configured to sense a measure related to the flow rate of a fluid flowing through the fluid channel. A porous insert is situated in the fluid channel, sometimes upstream of the flow sensor. When so configured, and during operation of the flow sensor assembly, a fluid may pass through the inlet flow port, through the porous insert, across the flow sensor, and through the outlet flow port. The porous insert may include pores that are configured to reduce the turbulence in the fluid passing the flow sensor.

摘要： A modular sensor assembly in which a sensing module may be packaged and provided separately from a signal processing module and which, in some applications, may facilitate disposal and/or replacement of the sensing module when exposed to a “dirty” or “contaminated” environment without requiring disposal and/or replacement of the entire sensor assembly. In certain applications, the sensing module may include at least one transducer or sensor and a local memory containing a set of conditioning coefficients. The sensing module may be removably coupled to a signal processing module which, in some cases, may be configured to download the set of conditioning coefficients stored in the local memory of the sensing module, and to use the set of conditioning coefficients to produce a substantially linearized output signal.

In one illustrative embodiment, a flow sensor assembly includes a housing with an inlet flow port, an outlet flow port, a fluid channel extending between the inlet flow port and the outlet flow port, and a bypass channel having a pair of taps fluidly connected to the fluid channel at separate locations. A flow sensor for sensing a measure related to a flow rate of a fluid flowing through the fluid channel can positioned in the bypass channel. A pressure differential between the two taps of the bypass channel can drive a fraction of a fluid flowing through the fluid channel through the bypass channel.

摘要： Flow sensor assemblies having increased flow range capabilities are disclosed. In one illustrative embodiment, a flow sensor assembly includes a housing with an inlet flow port, an outlet flow port, and a fluid channel extending between the inlet flow port and the outlet flow port. One or more partitions are provided in the fluid channel of the housing to define two or more fluid sub-passages. A flow sensor, for sensing a measure related to a flow rate of a fluid flowing through the fluid channel, is positioned in one of the two or more fluid sub-passages. In some cases, the cross-sectional area of each of the two or more fluid sub-passages may be substantially the same, but this is not required. The housing may be formed from a single molded part defining the inlet and outlet flow ports, at least a portion of the fluid channel, and one or more of the partitions. In this case, a top cover may be provided and mounted to the housing to define the remaining portion of the fluid channel, if desired.

摘要： A fluid flow sensing device can include a tapered fluid flow channel formed into a main channel defining a fluid flow tube as an alternate fluid flow path. A tapered fluid flow channel can bypass some fluid flow from the main fluid flow channel into said alternate fluid flow path and a flow sensor disposed within said alternate fluid flow path. The tapered flow channel is tapered in a direction of fluid flow toward said flow sensor to thereby reduce flow eddies and enable optimal sensing performance by fluid flow sensor. An upstream fluid flow channel and a downstream fluid flow channel can be molded into the main fluid flow channel, especially bypassed in the fluid flow path of the main fluid flow channel. A fluid flow sensor can be placed between the upstream fluid flow channel and the downstream fluid flow channel for measuring fluid flow rate the channel.
