Is this the world's smallest mass flow an pressure controller?
This system will be used by the trials assessors to determine the actual hydrogen consumption as the totaliser can easily be re-set to zero by the adjudicator before the start of each phase of the test. Hydrogen gas flow can be determined accurately over a wide flow range and, being a mass flow measurement, it is an absolute consumption measurement, unaffected by gas density changes resulting from pressure or temperature variations.
