<p>The gauge for measuring large diameter comprises a number of measuring units. Each measuring unit includes two position elements (11, 12), a fastener (14) and a body (13). These units are disposed on a circular surface and fixed by the fasteners one by one during measuring, until the remainder gap is not enough to dispose another measuring unit. Measuring the relevant geometric parameters and calculating the diameter according to the equation (I).</p> |
