The opening is designed to receive the flow sensor. The housing at the second front face, which is opposite the first front face, is conical. A first flushing opens to the housing interior, where the opening opens into the end region of the cone, and a second flushing opens to the housing interior. A fastening unit is designed to fasten the flow sensor in the housing, and a first wall holder is designed to be fastened to a wall. The first wall holder comprises a joint in the region of the second front face, with the joint connecting to the housing. The housing can be moved via the joint from a measurement position into a maintenance position.

  • Publication number: 20040194242
    Abstract: A multi-surface towel is afforded. A first piece of material has an absorbent surface. A second piece of material is coupled to the first piece of material and has a surface suitable for polishing. A third piece of material is coupled to the first and second piece of material and has an abrasive surface. Thus, the towel is multi-functional.
