FREQUENCY TUNING METHOD FOR A TUBE ARRANGEMENT
First Claim
1. A method for changing at least one interim eigenfrequency of a tube arrangement formed by means of at least one tube, and/or a tube serving as a measuring tube of a measuring transducer of the vibration-type, for tuning said interim eigenfrequency to a target eigenfrequency deviating therefrom, wherein the tube has a tube wall, and/or an at least sectionally circularly cylindrical, tube wall, as well as a stiffening element, and/or a stiffening element of material connectable with the material of the tube by material bonding and/or a platelet shaped, stiffening element, placed on the tube wall, on an outer lateral surface of the tube wall, and co-determining said interim eigenfrequency of the tube arrangement, which method comprises a step of:
- removing volume from the stiffening element.

Abstract
The method serves for changing at least one eigenfrequency of a tube arrangement formed by means of at least one tube particularly, however, also for tuning the interim eigenfrequency to a desired eigenfrequency deviating therefrom and referred to as a target eigenfrequency. The tube has a tube wall, of metal and/or an at least sectionally circularly cylindrical, tube wall as well as a stiffening element of metal and/or a stiffening element of material connectable with the material of the tube by material bonding and/or a platelet shaped, stiffening element, placed on the tube wall and co-determining the interim eigenfrequency of the tube arrangement. For the purpose of changing the interim eigenfrequency, it is provided, that volume is removed from the stiffening element, for instance, by means of laser.
