What is the breakup?
The hole meter is a measuring device for determining the size of the inner hole, cylinder or pipe. In conjunction with a micrometer or main calibration rings, the opening breakup can provide a precise reading of the size of the hole. The measurement is derived by inserting the base of the opening meter into the opening to measure, and gently moves the base until the hole diameter precisely suits. Available devices include dialing and electronic meters with various configurations of basic bases. The centralization mechanism loaded with spring combined with a fixed and one movable point provides very accurate measurements. These measures may have bases with variable size for use with different size opening sizes or may have interchangeable extension pins to adjust the base size.
The user records the inoric diameter of the tube end and selects a base or extension pin of a suitable size. Using the main calibration ring or micrometer the user determines the distance between the fixed point and the face of nAnd the base and records reading. Reading the dial on the breakup has a frame that is null to match the size of the base used.
The base is inserted into the pipe hole at a slight angle. Once the base is inside, the user moves it gently back and forth until the meter is centered in the pipeline. The hole meter is then removed from the pipe and the measurement is read on the dial. The result, either a positive or negative number, is added or subtracted from the micrometer or the main calibration ring to calculate the final result.
Some meters can replace a traditional digital or electronic display. The electronic reading is calibrated by the measurement of the meter base in the main calibration ring. Any subsequent measurements are compared with this calibration point. The base of the meter is similarly inserted into the hole opening and moves back and forth until the meter is centered. Reading indicates “minimalthe Úal "measurement that is the diameter of the opening at the point where he was measured.
Fully electronic holes of holes are now available that reads the boreholes with converters to signal values. Models include units connected to the cable and other wireless technology. Electronic meters can be made with two or three sensor points for measurement accuracy. Some measures can be modified by extensions to measure greater depths and wider size range.
