HOT WIRE ANEMEOMETER Abstract An electronic anemometer for measuring air mass flow in a conduit having a straight length of temperature-dependent resistive wire; a circuit board for holding at least a portion of the electronic circuitry used when the anemometer is operat- ing to maintain the wire at a substantially constant temperature and generate an air mass flow-indicating signal based upon the air mass flow in the conduit sampled by the wire, the circuit board being mountable on the exterior of the conduit, a rigid support plate having a pair of spaced-apart openings, the plate being fixedly attached to the circuit board; a pair of electric- ally nonconductive support inserts, each of the inserts being fixedly retained within one of the openings in the support plate; and a pair of electrically conductive, resilient posts capable of withstanding the elevated operating temperatures encountered when the anemometer is operating, each of the posts having a wire-supporting end portion fixedly connected to the wire, the end portions being spaced apart and positioned in a central portion of the conduit with the wire substantially transverse to the direction of airflow therein, the end portions being biased away from each other to hold the wire under ten- sion, each of the posts further having a remote end portion extendable through an opening in the wall of the conduit and fixedly held by one of the support inserts, the remote end por- tions being electrically connected to the electronic circuitry.
