  • Measurement knowledge from Testo

    The Pitot tube opening records the entire pressure and transmits this on to connection a of the pressure probe. The purely static pressure is recorded via lateral slots and transmitted to connection b The resulting differential pressure is the velocity dependent dynamic pressure. This is then analyzed and displayed.
