Abstract: A mount for elements of a water or heating installations is provided that includes a base body and a retaining clip that extends around one of the elements and releasably attaches it to the body. The base body and retaining clip are shaped to fit the elements. The retaining clip is U-shaped, has two legs and is made of a resilient, sound-damping plastic. The ends of the legs are bent back in a V shape and first detent projections are formed on the outside of the leg ends. The base body has openings matched to the legs. Formed on the inner wall of the openings are second detent projections, which cooperate with the first detent projections. The ends of the legs are designed to be manipulated by hand.

Abstract: A device for indicating and regulating the flow volume in a fluid circuit of a heating or cooling system is provided. The device includes a housing having a lower valve part, a conical bore, and a sealing seat. The device further includes an indicating element having a hollow-cylindrical inspection glass with a closed end, an open end, an indicator plunger axially movable therein and stressed by means of a spring. A regulating cone is attached to the open end of the inspection glass, whereby the free end of the indicator plunger is guided through the regulating cone and bears a flow body immersed in the conical bore. Also, the regulating cone has slots distributed at the periphery and extending to the indicator plunger.

Abstract: A fitting for measuring the flow rate of a hydraulic medium through a pipeline having a cylindrical fitting housing with a main flow channel includes a flow meter device with a measuring element and an indicator element. A side chamber is formed in a side connecting piece of the fitting housing. The flow meter device is arranged in the opening of the side connecting piece closing it off to the outside. In a measuring bore that forms the forward flow to the side chamber, a rebounding plate of the measuring element is arranged, which is connected by an indicator rod with an indicator of the indicator element. The main flow channel between intake bore and the outlet bore of the fitting is formed by the measuring bore that leads into the side chamber, the side chamber itself, as well as a transverse bore that adjoins the side chamber. As a result, the entire flow of the main channel runs through the side connecting piece with the measuring bore and the side chamber.

Abstract: A flow meter, particularly for warm water heating systems, includes a measuring element and an indicator element. The indicator element has a basic component with a cylindrical attachment extending into the collector pipe. An indicator rod with a rebounding plate extends into the measuring element and vertically slidable. According to the invention, a filter is installed ahead of the rebounding plate in the flow direction of the heating medium. Where the basic component extends to a cylindrical attachment affecting the flow against the rebounding plate, it is suitable to provide a number of slits in the cylindrical external wall of the lower portion of the attachment, the slits being distributed around the perimeter parallel to the axis. In this manner, dirt particles, which could impair the function of the indicator, are virtually filtered out.
