I measuring device for heat consumption. Patented in the German Empire on December 16, 1911.

There are already devices to determine consumption and thus costs, which the heating of individual (e.g. heated from a central heating system), if necessary of rented rooms. The present invention now particularly relates to one simple embodiment of such a device.

The heat measuring device is placed directly behind the radiator valve (in the case of steam heating) or installed behind the regulating tap (for hot water heating systems), but can also be used for entire groups of radiators find by switching the same into the supply line.

On the accompanying drawing, Fig. 1 shows the heat measuring device in a longitudinal section, while FIG. 2 is a plan view of FIG.

The same consists of an elongated cylinder α made of transparent material (e.g. glass), the lower end of which, designed analogously to a bottle neck, is connected to a metal tube b by a fitting. A hollow zinc rod c inserted into the body thus formed and sealed in the fitting rests with its lower end on a transverse bolt d inserted into the tube b , while its upper end rests against a valve e , which is in the lid f closing the glass cylinder α inserted and held by a spring g on its seat. An empirically established scale is attached to the glass cylinder or a sleeve enclosing the same, which has a longitudinal slot which partially makes the glass cylinder visible.

The apparatus described is screwed into the radiator with the lower pipe end b ' behind the radiator valve or faucet, so that the heating medium can penetrate into the pipe b while its entry into the cylinder α is prevented.

The latter is then filled with distilled water up to a certain mark.

As soon as the radiator valve (for steam heating systems) or the regulating valve (for hot water heating systems) is opened, the pipe b fills with the heating medium, which heats the zinc rod c and causes it to expand. As a result, the latter heats the water in the cylinder α and at the same time opens the valve e, through which air enters, so that evaporation of the water in the cylinder α is brought about.

The higher the temperature of the radiator and the longer it provides heat, the more more water evaporates.

The loss of water in the glass cylinder α is based on the heat consumption, and the latter can be read off the scale at any time.

The device described can also be used to measure the amounts of heat in others Apparatus, e.g. B. bath stoves provided with heating coils can be used.

It must of course always be determined the amount of heat consumed before all the water in the cylinder α has evaporated, and the device described can with a

Claims (1)

Signal apparatus are connected, which indicates a certain low level of the distilled water in the cylinder α in time. To refill the distilled water, a plug i is attached to the upper cylinder lock, which can be opened with a key, so that refilling by unauthorized persons and thus disturbance of the counting process is excluded.
\ o To vent the iron pipe b, especially when the heating is started, a vent screw h is inserted at the upper end of the former.
