Heat supply measuring device - has membrane moving under effect of pressure difference between fluid supply and return pipes

摘要

The device used to measure quantities of heat in liquid or gas heat transport systems. A measurement membrane (3) is set in movement when there is a heat consumption on the installation served. The movement of the membrane (3) is caused by a pressure difference between its two faces. This is obtained by the flow and the temperature deviation on the installation. The movement is limited to the volume of a perforated box (4) which can move between 2 fixed points, the passage being a free one without intermediate stoppage. This is achieved using a magnetic valve.
