Abstract
A flow measurement device and a method of manufacturing a flow measurement device having a measurement tube made from plastic or at least a plastic liner are provided. According to an exemplary embodiment, the measurement tube can be fabricated from plastic in an injection molding apparatus. Thereafter, electrical components of the measurement tube, such as electrodes and a coil holder, for example, can be concomitantly injection molded in a common, separate injection molding process. The electrical components can there be installed easier and more reliably in position.
Claims15
A method of manufacturing a flow measurement device having a measurement tube made from plastic in which electrodes in contact with a substance to be measured are arranged, the method comprising:
- fabricating the measurement tube together with process connections in one piece from plastic in an injection molding process;
- and
- fabricating the electrodes, a coil holder and electrical components of the measurement tube concomitantly in a common injection molding process separate from the fabrication of the measurement tube and process connections.
