Problems solved by technology

[0002] It is known that in the state of the art water or heat meters and their transmitters have housings made of brass and are therefore expensive
In addition, housings made exclusively of plastic are known, which can be produced inexpensively, but such plastic housings have little market acceptance because these housings are relatively difficult for the assembly process and for the permanent loads of the installation in the pipeline. small intensity

Embodiment Construction

[0025] figure 1 A perspective view of the metal pipe 1 is shown. The metal tube 1 is preferably made of steel because the cost of steel is relatively low and the price fluctuation is less than that of brass used for water / heat meters 2 under the prior art conditions. The wall 3 of the metal tube 1 has an opening 4 which is preferably in the middle of the longitudinal extension of the metal tube 1. For example, the opening 4 can be processed in the metal pipe 1 by punching or milling.

[0026] The two ends of the metal pipe 1 each have threads 5 arranged on the outer wall 3.1 of the metal pipe 1 as a device for connecting to the pipeline system, for example, threads can be machined in the outer wall 3.1.

[0027] Put the metal tube 1 processed in this way into an injection mold, and then pour or inject the plastic into the injection mold, so that the attached parts can be mass-produced at low cost. figure 2 The transmitter housing 6 shown. Attached image 3 Shown is a cross-secti...

Abstract

The meter has a measuring device including a transmitter, and a transmitter housing (6) formed as a composite part made from a plastic part (7) and a metal tube (1). A wall of the metal tube includes an opening, where the opening is enclosed by the plastic part. The plastic part partially covers a front surface of the metal tube originating from an inner wall (3.2) toward an outer wall (3.1) of the metal tube. A measuring chamber (9) for the transmitter of the measuring device is provided in the plastic part in a direction of the opening of the metal tube. An independent claim is also included for a method for producing a transmitter housing for a water / heat meter.

Description

Technical field [0001] The invention relates to a water meter / heat meter with a transmitter housing and a method for manufacturing the transmitter housing. Background technique [0002] It is known that under the conditions of the prior art, the housing of the water meter or the heat meter and its transmitter are all made of brass, which is expensive. In addition, it is also disclosed that the shell made of plastic only can be manufactured at a low cost, but the market acceptance of such plastic shells is very small, because these shells have a comparatively good effect on the assembly process and the permanent load installed in the pipeline. Small intensity. Summary of the invention [0003] The task of the present invention is to provide a water meter / heat meter with a low-cost and solid transmitter housing and a method for manufacturing a solid and solid transmitter housing of the water meter / heat meter at low cost. [0004] The water meter / heat meter has a transmitter housing ...
