A nozzle assembly operable to deliver fluid to a tank to be filled and to sense a level of fluid in the tank, the assembly having a fluid outlet and a sensor portion, the sensor portion comprising a pressure sensor provided in fluid communication with a sensor conduit, the sensor conduit having a sensor conduit aperture provided therein, the assembly being operable in use whereby when a level of liquid in the tank being filled rises above a level of the sensor conduit aperture, the sensor conduit aperture is closed by the liquid and a pressure of gas trapped in the sensor conduit increases thereby indicating a“tank full”condition, the assembly being arranged to detect the increase in pressure of gas and to generate a pressure increase signal indicative of the in crease in pressure when the increase in pressure is detected.
