Abstract
The invention relates to a measuring system for determining a dispensed amount of hydrogen of a hydrogen dispensing location from a hydrogen dispensing unit present there to a receiving tank including a measuring unit. The measuring unit can have a flowmeter, wherein the measuring system is designed to establish a fluid-tight connection between the hydrogen dispensing unit and the receiving tank. Furthermore, the flowmeter has an active cooling. The invention further relates to a measuring method for determining a dispensed amount of hydrogen.
Claims14
A measuring system for determining a dispensed amount of hydrogen of a hydrogen dispensing location, in particular a hydrogen fueling station, from a hydrogen dispensing unit in form of a filling point present there to a receiving tank,
- the measuring system comprising
- a measuring unit,
- wherein
- the measuring unit including a flowmeter which can be arranged between the hydrogen dispensing unit in form of a filling point and the receiving tank,
- the measuring system is designed to establish a fluid-tight connection between the hydrogen dispensing unit in form of a filling point and the receiving tank whereby a fluid-tight connection is established from the hydrogen-dispensing unit in the form of a filling point to the measuring unit and a fluid-tight connection can be is established from the measuring unit to the receiving tank,
- the measuring unit is designed to lead hydrogen dispensed by the hydrogen dispensing unit in form of a filling point through the flowmeter of the measuring unit to the receiving tank and
- the flowmeter has is actively cooled in that the flowmeter has an active cooling system which is designed to cool the flowmeter before the start of the transfer of the hydrogen in such a way that there is essentially no change in the temperature in the flowmeter during the transfer.
A method for determining the dispensed amount of hydrogen of a hydrogen dispensing location, in particular a hydrogen fueling station, with a hydrogen dispensing unit in form of a filling point to a receiving tank, the method comprising:
- using a measuring system according claims,
- wherein a fluid-tight connection is established between the hydrogen dispensing unit in form of a filling point and the measuring unit as well as between the measuring unit and the receiving tank,
- wherein via the fluid-tight connection hydrogen is transferred from the hydrogen dispensing unit in form of a filling point via the flowmeter of the measuring unit of the measuring system to the receiving tank,
- wherein the throughflow of hydrogen through the flowmeter is determined during the dispensing of the hydrogen from the hydrogen dispensing unit to the receiving tank and
- wherein the flowmeter is actively cooled before the beginning of the transfer of the hydrogen from the hydrogen dispensing unit to the receiving tank such that substantially no change in temperature occurs in the flowmeter during the transfer.
