  • Method for measuring the control cross section area of a nozzle
    Patent number: 5207089
    Abstract: The method for measuring the cross-sectional area of a nozzle by a pneumatic through-flow method with supercritical pressure ratio measures the volume flow flowing through the nozzle on its input side by a differential pressure measurement at a resistance distance through which a laminar flow passes. Deviations of the temperature of the test medium from a reference value are determined by a temperature sensor and accounted for via a correction factor.
