An air flow rate meter includes a probe housing having a pass-through opening. The air flow rate meter also includes a sensing circuit coupled with the probe housing and positioned at least partially within the pass-through opening. The air flow rate meter also includes an arm coupled to the probe housing. The arm includes a probe-end on which the probe housing is disposed, a mounting-end opposite to the probe-end, and an angled segment extending at a first angle from the probe-end and at a second angle from the mounting-end.
