Abstract
A large diameter gauge consists of a series of measuring units. Each measuring unit comprises two positioning elements(11,12), a fastener(14) and a body(13). These series of measuring units are placed and fixed sequentially and head to end or end to head around the circumference of the cylinder or hole to be measured during measuring until the remained space is not large enough to be put into another one measuring unit. Measuring the distance between the first measuring unit and the last measuring unit, the diameter to be measured can be obtained through the geometric relations between the gauges and the cylinder or hole to be measured.
