How many related terms do you know about the following gas meter?
    1Magnification:The size increment given by the amplifier. For systems in which the magnification is adjustable in the gas meter, this adjustment is achieved by adjusting the size of the back pressure using the calibration gauge, while for systems with fixed magnification, in order to obtain precise measurements, higher accuracy requirements can only be put forward for the pneumatic probe.
    2, nozzle:A damping hole on the pneumatic measuring head for ejecting air to the workpiece under test. The diameter of the nozzle hole is determined by the pneumatic gauge system used. The number and position of nozzle holes are determined by the application of the measured workpiece.
    3, resolution:Zoom in on the smallest increment value in the range displayed.
    4Pressure regulator:A device used to regulate the flow or pressure of air. For example, a damping hole with precise dimensions, or a needle valve, or both.
    5, zero position:Amplifier setting The process of determining the position of the measured range after amplification. The zero position is usually chosen at the midpoint of the full scale, and the displayed value can be located anywhere within the full scale range.

    6, zero size:The expected value or nominal size of the measured size. In a back pressure system, the zero size is usually the middle of the maximum and minimum, while in a flow system, the zero size is usually the minimum.
