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.

The porous insert may include pores that are configured to reduce the turbulence in the fluid passing the flow sensor.

摘要： A high mass-flow sensing apparatus and method of forming the same, comprising a flow tube bypassed in a flow path defined by a flow channel, through which a fluid flows. A flow sensor can be disposed in the flow tube for measuring a flow rate of the fluid in the flow channel. A set of narrow rectangular flow restrictors can be molded into the flow tube and adjacent to the flow sensor. Each flow restrictor can include several rectangular cutouts that are molded into upstream and/or downstream portions of the flow tube in order to limit the flow rate of the fluid across the flow sensor. The flow restrictors can laminarize the flow rate of the fluid in the flow tube and thereby reduce flow turbulence and lead to optimal sensing performance of the flow sensor.

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.
