automatic controlling of gas consumption, possibly in branches of industry needing constant gas flowrate at fluctuation of pressure and temperature values. SUBSTANCE: controller includes housing with outlet window having seat closed by means of elastic sensing member in the form of plate secured to carriage by cantilever fashion. Heat sensitive member is also secured to carriage in such a way that free end of cantilever engages with elastic sensitive member. Upon heating gas, heat sensitive member decreases gas pressure acting upon elastic sensitive member and therefore volumetric gas flowrate is increased. Heat sensitive member may be in the form of bimetallic strip; carriage may be mounted with possibility of motion relative to window, lengthwise and crosswise. EFFECT: stable consumption of gas in wide range of pressure and temperature values. 3 cl, 1 dwg
