HEAT COST DISTRIBUTOR BASED ON THE EVAPORATION PRINCIPLE, FOR THE MEASUREMENT OF HEAT CONSUMPTION OF RADIATORS

摘要

A dispenser heating costs comprising a rear housing part (1) and a front housing part (2) containing a bulb (6) containing an evaporating fluid (7) is closed by a lead seal (12) proof truquages. In order to make reading easier, a prism (13) used to direct an outside light beam at the meniscus (17) of the evaporating fluid (7). The light is projected by a reading arrangement mountable by means of an adapter on the front housing part (2). This arrangement comprises a sensor device for detecting the position of the meniscus (17). A reading window (4) is constructed in a special way to avoid parallax errors.
