Air Flow Sensor

This air-flow sensor comprises a cylindrical housing 3 having an end cap 5, provided with an exit opening 7 in the lower half of the cap, as shown.

A dividing wall or septum 9 extends rearwardly from the cap 5 and has a sensing element 11 mounted in an opening 13. At this same location an air-entry opening 15 is provided in the housing 3.

The air current enters the housing at 15, flows over sensor 11, and then through the lower portion of the housing 3, beneath the wall 9, and exits from opening 7.

The well-defined path for the air flow gives more reliable and consistent outputs from the device.
