Protection device fro hose used to transfer fuel from tanker to filling station storage tank

摘要

A protection device for the hose used to transfer fuel from a tanker to a filling station storage tank has a control panel on the tanker, receiving details about the state-of-fill for the tank and which opens the valve when the hose is properly connected. On both coupling halves for the hose and tank is a reading device, each being connected to the control panel. The tank one has a plug connector. On the hose coupling are coding marks which are identical or give a preset combination. They may be coloured or just geometric shapes. The connection between the reading device on the tank and the control panel is a wire-free connection, ie, uses an optic fibre.
