Filling device for filling e.g. gaseous hydrogen into tank in lorry, has supply conduit comprising electric conducting element that cooperates with transmitter to transmit measurements sent by transmitter by electric conduction process

摘要

The device has a fluid supply conduit (3) for connecting a fluid distribution device (2) and a tank (1) to allow distribution of a fluid in the tank. A sensor (4) performs measurements (11) of a physical parameter e.g. pressure, temperature and density, of the fluid. A transmitter (5) sends the measurements carried out by the sensor through electromagnetic waves. The fluid supply conduit comprises an electric conducting element (9) that cooperates with the transmitter by an electromagnetic coupling (8) to transmit the measurements sent by the transmitter by an electric conduction process. The sensor is designed as a piezoelectric or piezoresistive-type pressure sensor. Independent claims are also included for the following: (1) an installation for filling a pressurized fluid into a tank (2) a method for filling a pressurized fluid into a tank.
