Title:
PRODUCTION OF A BENT MEASURING TUBE FOR A VIBRATION-TYPE MEASURING SENSOR
Document Type and Number:
WIPO Patent Application WO/2005/108931
Kind Code:
A2
Abstract:
In order to produce a measuring tube, a solid shaped body (2), which is comprised of a first filling material (21) and of a second filling material (22) incorporated therein, and which stabilizes the cross-section of the discharge tube (1') when bent, is formed inside the passageway of the discharge tube (1) to be bent. A hardened liquid, particularly wax, grease or water, serves as filling material (21) and has a melting temperature lower than a melting temperature of the discharge tube (1'), whereas an, in particular, granular and/or powdery loose-packed material (22) that, in a normal state, can, in essence, be poured, particularly granular material, sand or the like, serves as the second filling material (22) that has a melting temperature higher than that of the liquid (21). After forming the shaped body (2), the discharge tube (1') is bent by introducing a bending force acting, at least in sections, upon the discharge tube (1') from the outside. Afterwards, the shaped body (2) is softened inside the passageway of the bent discharge tube (1 ) whereby permitting the filling material (21) provided in the form of the hardened liquid is to melt inside the bent discharge tube (1 ).
