The Multi-finger Caliper Tool (MCT) is a mechanical tool for well diameter measurement. It is mainly composed of measuring fingers, driver rod and inductive sensors. The sensing section consists of 24, 40, or 60 displacement sensors, which are uniformly distributed on the outer circumference, with each sensor able to measure the slightest variation in diameter. The tool also includes an inclination sensor and a rotation sensor.
