ABSTRACT:
A heat circuit comprises an initial conduit containing a flow medium and a return conduit. A choke element located in a conduit such as the initial conduit of a heat circuit serves to control the flow of the flow medium. The choke element has several active positions in which openings having differently sized cross-sections are inserted into the path of flow. The choke element is moved by a drive so that a particular position of the choke is active. A differential pressure sensor measures the presure difference before and after the choke element. A computer resposive to the differential pressure sensor controls the drive so that a particular cross-section of the choke element takes effect and the flow of the medium is measured with sufficient precision over a wide measuring range. The inventive arrangement may also include a temperature sensor for measuring the temperature difference between the initial and return conduits. The computer which controls the choke drive may also be responsive to this temperature difference.
