| Intended for the measurement of | Hydrogen($\mathrm{H}_{2}$) |
Each CG dispenser consists at least of one measuring system made up of the following essential parts: A flow meter (measurement sensor and transducer); and
- A calculating/indicating device.
The same housing of the dispenser can comprise of one or more measuring systems. When more than one measuring systems are in one housing, one calculating/indicating device may be a common part of the measuring systems.
To correct the amount of hydrogen delivered, the electronic calculating and indicating device takes into consideration that the dispenser is an empty hose measuring system and also the pressure, temperature and volume of relevant sections of the dispenser. Pressure and temperature of relevant sections are measured via transmitters, and the volume is configured in the calculating/indicating device. The monitorization of the pressure and temperature allows stopping or even not starting a delivery if out of range values according to the fuelling protocol are measured and this also guarantees the integrity of the measurement.
In Table 2 the overview of the essential parts of the measuring instrument are presented.
