A method includes disposing an intervention service tool within a tubular. The intervention service tool includes an anchoring system, a shifting system, and a linear actuator system. The tubular includes a shifting profile geometry disposed within the tubular at a first location. The anchoring system, the shifting system, and/or the linear actuator system is actuated. Shifter system pressure, linear actuator system force/pressure, and displacement of the shifting system is measured. A known graph of the shifting profile geometry is compared to one or more of a measured pressure, a measured force, or a measured displacement. A position of a key disposed on the shifting system is determined relative to the shifting profile. The shifting profile geometry is engaged with the key based on the position of the key. The shifting profile geometry is positioned at a second location that is different from the first location.

A method is disclosed that includes measuring an inner diameter (ID) of a tubular at least at a plurality of points along an inner circumference of the tubular, at a predetermined axial distance from an end of the tubular, to yield a first set of measurements. A computer processor is used to: create a tubular profile from the first set of measurements, wherein the tubular profile represents a unique identification code of the tubular; save the profile; and thereafter identify the tubular. The tubular is identified via: receiving a second set of measurements of the ID of the tubular from at least at a plurality of points along an inner circumference of the tubular, at the predetermined axial distance from the end of the tubular; and comparing the second set of measurements with the saved tubular profile to identify the tubular.

Examples of determining tuberculation in a fluid distribution system are disclosed. In one example implementation according to aspects of the present disclosure, an acoustical wave generator generates an acoustical wave within a fluid path of a fluid distribution system. A first acoustical sensor and a second acoustical sensor sense the acoustical wave. An acoustical signal analysis module determines an amount of tuberculation within the fluid distribution system by analyzing the sensed acoustical wave.

A method for determining an inner diameter of a sounding tube, which, for measuring the fill level of a fill substance located in a process space of a container, extends in the process space, or is placed alongside the container and connected with the process space. The method can be implemented in the case of a fill-level measuring device working according to the FMCW-principle. Besides the intermediate frequency of the difference signal, also its phase shift is ascertained, wherein the exact tube inner diameter can be determined based on the phase shift. An advantage of the method is that the fill-level measuring device with the help of the then exactly known tube diameter can be recalibrated and accordingly the fill level determined more exactly. The exact tube inner diameter does not have to have been previously known.

Measuring device for measuring a rotationally symmetrical cavity in a workpiece has a base body for supporting on the workpiece, and a measuring head with a sensor for scanning the inner wall of the cavity. The measuring device has a shaft connected to the base body. Measuring head is movable relative to base body in the axial direction of the shaft and is rotatable about a rotational axis defined by the shaft. The shaft is configured as a hollow shaft, and accommodates a drive shaft rotationally drivable by a rotary drive apparatus. A distal end of the drive shaft is connected to the measuring head in a rotationally fixed manner. The shaft is situated on the base body and movable in the axial direction of the shaft by a slide bearing system. An axial drive apparatus moves the shaft relative to the base body.
