FIELD: measuring technique. ^ SUBSTANCE: gas flow rate comprises two tanks that are connected with main pipelines for supplying and discharging gas through the tree-composition control valves. The tanks are provided with top pressure-tight lids, and the volumes of the tanks are the same. In addition, the flow meter has unit for control of valves, two relays connected with the control unit, devices for closing the contacts of the relay secured to the floats mounted in each tank, and pipe that interconnects the tanks. The ends of the pipelines for supplying gas and pipe are submerged into the tanks. The depth of the pipe ends is higher or equal to the depth of the ends of the pipelines for supplying gas. The ends of the pipelines that connect the tanks with the main pipelines for discharging gas are mounted above the levels of liquid in the tanks. ^ EFFECT: enhanced accuracy of flow measuring. ^ 1 dwg |
