  • Handheld digital manometer
    Patent number: 10495496
    Abstract: Systems and methods for measuring a flow rate through a nozzle include generating a first polynomial relationship between pressure and output voltage for a first pressure transducer located at one end of the nozzle and generating a second polynomial relationship between pressure and output voltage for a second pressure transducer located at another end of the nozzle. When a first voltage signal is received from the first pressure transducer and a second voltage signal from the second pressure transducer, the associated first and second pressures are generated based on the first and second polynomial relationships. A flow rate through the nozzle is then constructed based on the difference between the first pressure and the second pressure.
