  • Patent number: 10620083
    Abstract: Method for monitoring and/or checking a pressure device having a lumen surrounded by a wall for conveying and/or storing a fluid. For such purpose, the method comprises a step of registering a strain, of the wall, by means of a strain gage, respectively a strain sensor formed therewith, affixed outwardly on the wall, for ascertaining a strain value representing the strain of the wall, as well as a step of using the strain value for ascertaining damage to the wall, as a result of plastic deformation of the wall and/or as a result of wear of the wall. A measuring system of the invention comprises supplementally to the pressure device at least one strain sensor affixed on a wall segment of the wall for producing a strain signal dependent on a time variable strain, of the wall segment as well as a transmitter electronics electrically coupled with the strain sensor.

  • Patent number: 10309866
    Abstract: The method serves for monitoring and/or checking a pressure device having a lumen surrounded by a wall for conveying and/or storing a fluid. To this end, the method comprises a step of registering both a strain of a first wall segment as well as also a strain of at least a second wall segment spaced from the first wall segment, for ascertaining a strain deviation value representing a difference between the strain of the first wall segment and the strain of the second wall segment, as well as a step of using the strain deviation value for ascertaining damage to the wall, as a result of plastic deformation of the wall and/or as a result of wear of the wall.

  • Publication number: 20180313487
    Abstract: An adapter comprises a connecting nozzle, a connecting nozzle as well as a connecting nozzle. The free nozzle ends of the connecting nozzles are adapted to be connected to line ends of fluid lines. The adapter includes, for guiding flowing fluid in and then out, two mutually separated, tubular flow channels, of which a flow channel extends from a flow opening located in the free nozzle end of the connecting nozzle to a flow opening located in the free nozzle end of the connecting nozzle and a flow channel extends from a flow opening located in the free nozzle end of the connecting nozzle to a flow opening located in the free nozzle end. Moreover, the adapter includes, bordering on a region of the free nozzle end located between the flow openings a projection, which extends from the nozzle end with a length to a free projection end remote therefrom.

  • Patent number: 8099850
    Abstract: The measuring transducer includes at least one measuring tube communicating with a line connected during operation for conveying a medium to be measured, and a support element oscillatably holding the at least one measuring tube. Additionally, it is provided that the support element contains at least two passageways, via which the at least one measuring tube communicates with the line, and that the at least one measuring tube is affixed, especially releasably, at least one end to the support element by means of a screwed-fitting at one of the passageways. Alternatively or in supplementation thereof, it is further provided that the at least one measuring tube is, at least in part, made of cold-strengthened, for instance cold-stretched or autofrettaged, material.

  • Patent number: 7610795
    Abstract: A method serves to adjust a mechanical natural frequency of a hollow body which at least partly comprises a ductile material, in particular a pickup housing of a measurement pickup or a measurement pipe of a measurement pickup. A static external pressure of an atmosphere surrounding the hollow body and/or a static internal pressure prevailing in a lumen of the hollow body, the lumen being sealed off substantially in a pressuretight fashion, is varied in order to generate a pressure difference between the lumen and the atmosphere surrounding the hollow body. The pressure difference is adjusted to a value that causes the material of the hollow body to expand, and at least a proportion of the material of the hollow body is made to flow under the influence of the pressure difference for plastically deforming the material. The method can readily be integrated into already-established pressure tests for measurement pickups of the vibrational type.
