Abstract
A method for filling a vehicle fuel tank with a gas is provided, in which the vehicle fuel tank (31) is connected to a delivery device (2) by a pressure-tight line (10) and the gas stored under pressure is filled into the vehicle fuel tank (31) from a storage unit (3) by means of the delivery device (2). The method comprises the following steps: the instantaneous value of a parameter, which is representative of the instantaneous level of filling of the vehicle fuel tank (31), is determined during filling with the aid of a sensor apparatus (32, 33) arranged in the vehicle fuel tank (31) the filling is ended when the parameter has reached a pre-settable end value.

A method for filling a vehicle fuel tank with gas from a storage unit holding the gas under pressure by directing gas from the storage unit via a delivery device and a pressure-tight line to the fuel tank, comprising flowing gas from the storage unit into the fuel tank, arranging a sensor apparatus in the fuel tank, with the sensor apparatus determining an instantaneous value of a first parameter which is representative of an instantaneous state of filling of the vehicle tank with gas, during filling detecting at the delivery device a mass of the gas supplied to the tank, from the supplied mass generating a control value that is comparable to the first parameter, comparing the control value with the first parameter, generating an error signal when a deviation between the first parameter and the control value exceeds a pre-settable limit value, and ending the filling when the first parameter has reached a pre-settable end value.
A method of operating a gas refueling plant including a storage unit holding gas under pressure, a delivery device for dispensing the gas from the storage unit, and a pressure-tight line for directing gas from the delivery device to a fuel tank, the method comprising flowing gas from the delivery device through the pressure-tight line to the fuel tank, arranging a sensor apparatus in the fuel tank, with the sensor apparatus determining an instantaneous value of a first parameter which is representative of an instantaneous state of filling of the vehicle tank with gas, during filling detecting at the delivery device a mass of the gas supplied to the tank, from the supplied mass generating a control value that is comparable to the first parameter, comparing the control value with the first parameter, generating an error signal when a deviation between the first parameter and the control value exceeds a threshold value, and ending the filling when the first parameter has reached a pre-settable end value.
