摘要： A high temperature gas flow sensing element module, using Pitot tube technology, for use within a fluid conduit consisting of a housing having an inlet, an outlet, and forming a hollow interior cross-sectional area. Individually, the gas flow sensing element modules fit easily through typical furnace access doors. Thus, in typical furnace retrofit applications, a plurality of equally sized gas flow sensing element modules are arranged adjacent one another in a manner such that the inside dimensions of the entire arrangement coincide with the internal dimensions of the plenum or duct opening into which it is inserted. Pressure averaging piping is used to provide average total and static pressure across the entire gas flow sensing element to differential pressure flow indicators and/or transmitting devices.

摘要： An multi-point, center-averaging airflow sensor comprises a plurality of upstream airflow sensing tubes extending radially from a central hub having a total pressure averaging chamber and a static pressure averaging chamber. The airflow sensing tubes are each provided with at least one total pressure port located inwardly of the outer end of the tubes to minimize error caused by total pressure measurements taken near the inner walls of the conduit in which the sensor is installed. The sensor has static pressure ports located in the side surface of the hub which are shielded from upstream air flow by the tubes and which are preferably at least partially shielded from damper back pressure by notched reinforcing blades provided along the length of the airflow sensing tubes.

摘要： A method of generating, for an aircraft, a total air temperature compensated for recovery or deicing heater error includes measuring a total air temperature with a total air temperature probe. A local angle of attack for the total air temperature probe is determined. Then, a corrected total air temperature, compensated for recovery or deicing heater error, is generated as a function of the measured total air temperature and the determined local angle of attack for the total air temperature probe.
