Flow sensing device including a tapered flow channel |
摘要 |
<p>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.</p> |
