The priority panel is the set of automatic valves and pressure sensors that, controlled by the PLC, detects the pressures of the plant and manages the filling sequence for the supply lines of the dispensers and storage sectors according to the preset sequence. Its function is to fill at maximum pressure on all lines, with priority for the high pressure – which guarantees the end of filling and therefore the possibility to disconnect the vehicle – then the medium, and finally the low pressure.
