Low pressure index continuous integrator

Claim 1

In a low pressure index continuous integrator assembly for measuring the throughput fluid flow of a meter having a pressure range of between 0 to 5 psig, the combination of: a. a housing having an upper frame and a lower frame, b. a pressure sensing means mounted on the upper frame, c. the pressure sensing means communicating with the fluid flow in the meter, and to expand or contract in a straight line responsive to increases or decreases in the pressure of the fluid flow, d. a continuous integrator mounted to the lower frame having a ring biased to rotate upon a rotative disc driven from the meter, e. the ring to rotate at a variable speed along a radial line on the surface of the disc defining an axis of rotation, f. an output shaft driven by the ring at a variable speed responsive to the ring''s radial position on the axis of rotation, g. a counter driven by the output shaft to indicate the corrected volume, h. a link transfer assembly interconnecting the pressure sensing means and the ring, i. the link transfer assembly having a first link connected to the pressure sensing means and a last link connected to the ring, j. the first link and the last link normally substantially parallel to each other except during periods when the ring is traveling along the axis of rotation to assume a new position of rotative stability responsive to pressure changes, k. the first link and last link disposed perpendicular to the axis of rotation, l. a plurality of intermediate links pivotally interconnected between the first link and the last link with each of the intermediate links disposed at a substantial right angle at the point of connection to the adjacent links, m. at least one of the intermediate links substantially parallel to the axis of rotation, n. at least one of the intermediate links substantially parallel to the first link and the last link, and o. a fixed pivot formed at the upper frame to interconnect two of the intermediate links at right angles to each other whereby the linear motion of the pressure sensing means will act to crank the intermediate links about the fixed pivot to transmit the motion to the last link which steers the ring in a linear path along the axis of rotation to a new location thereon, corresponding to the new pressure condition sensed at the pressure sensing means.
