  • Non-nulling gas velocity measurement apparatus and performing non-nulling measurement of gas velocity parameters
    Patent number: 11525840
    Abstract: A non-nulling gas velocity measurement apparatus performs a non-nulling measurement of gas velocity parameters and includes: a non-nulling pitot probe; gas valves in fluid communication with a different entrant aperture of the non-nulling pitot probe via a different pressure channel; receives stagnant gas from the respective entrant aperture; receives a reference gas; receives a valve control signal; and produces a valve-selected gas based on the valve control signal, the valve-selected gas consisting essentially of the reference gas or the stagnant gas; and a plurality of differential pressure transducers, such that each differential pressure transducer: is separately and independently in fluid communication with a different gas valve, and that gas valve communicates the valve-selected gas to the differential pressure transducer; receives the valve-selected gas from the gas valve; and produces a differential pressure signal from comparison of the pressure of the valve-selected gas to a reference gas pressure
    Type: Grant
