Automatic dosing gun - has sensing device for the level of fuel going through the gun into a container

摘要

Fluid passes through the gun into a container until lever of fluid or its roam reached top and disturbs the slight vacuum created by the outflowing fluid. The slight vacuum becomes a slight over pressure. This will activate a membrane which in turn will close the supply. Since the movement of the main blocking valve is slowed down, no hydraulic shocks will occur if this valve is automatically closed.
