A vehicle 1 with a tank 2 having a dry line liquid delivery system 3 is immobilised by a control means 4 when liquid is detected by a sensor 7 at a position in a delivery hose 6. The liquid may be detected at highest point in the hose leading to a hose real. The system may further comprise a gas extractor to ensure only the liquid to be delivered is monitored. A filter may remove any debris upstream of the gas extractor. The immobilisation may be for example electrical/electronic disabling of the engine or vehicle system or a brake interlock. Further disclosed is an emergency over-ride. |
