Problems solved by technology

When floating flanges are used in combination with measuring tubes of the type of measuring device of interest here, the disadvantage is, of course, that the manufacturing costs are rather high due to the welding between the measuring tube and the pre-welded bead

Embodiment Construction

[0026] According to FIG. 1 , the tube semi-finished product is the basis for manufacturing the measuring tube 1 . Under the situation of considering the length crimping, the length of the expected finished product size of the measuring tube 1 is cut to length by the fixed length of the pipe semi-finished product. The measuring tube 1 consists of a deep-drawable steel sheet whose wall thickness is adapted to the wall thickness of the (not shown) further extending conduit system.

[0027] According to FIG. 2, two floating flanges 2a and 2b are slipped on the cut-to-length conduit element in order to prepare the workpiece for the next manufacturing process.

[0028] According to FIG. 3 , the two ends of the conduit element are crimped in a subsequent manufacturing step, so that the two floating flanges 2 a and 2 b can no longer be removed from the measuring tube 1 . In this exemplary embodiment, the bead section 3 is formed only as a radially outwardly extending edge region, whi...

Abstract

The invention relates to a magnetic inductive flow meter, comprising a burette (1) made of metal. The burette can be embedded into a duct (6) through float flanges (2a and 2b) positioned at the end side, wherein, the float flanges (2a and 2b) work together with a coil-edge section (3) which is formed and molded on the end side of the burette (1).

Description

technical field [0001] The invention relates to a magnetically inductive flow meter having a metal measuring tube which can be inserted into a conduit via a floating flange at the end. Furthermore, the invention relates to a method for producing such a measuring tube. Background technique [0002] Magnetic flow meters are used to measure the flow of liquids, pastes and pastes through the conduit system of most industrial equipment. The premise of using a magnetic induction flowmeter is that the measuring medium has a certain minimum conductivity. The interesting flow measuring device here is distinguished by its precise measurement results, wherein no pressure losses are caused by the measurement in the line system. In addition, magnetic induction flow meters have no movable or protruding parts into the burette, which are particularly prone to wear. [0003] The flowmeters of interest here can be used in the chemical industry, pharmaceuticals, cosmetics industry, municipa...
