Abstract: A variety of instruments are used to measure volumes of gases through rotary, positive displacement, and turbine meters. The mechanically driven integrator is the most widely used instrument for this purpose. The integrator is mounted on the meter so the output wriggler of the meter engages directly with the input wriggler of the integrator. Gas flowing through the meter provides the mechanical force required to operate the integrator. The pressure within the meter operates the pressure element and linkage, while the temperature system responds to the changes in temperature of the flowing gas. The changing pressures and temperatures are integrated into the total corrected readout of volumes in cubic units by means of cams, ratchet, or rings in the integrating mechanism.
