Mass flow meters provide accurate gas measurement regardless of temperature or pressure changes, making them ideal for CNG fueling. They measure the actual mass of gas delivered instead of its volume, which can vary significantly.
These meters improve transaction fairness and eliminate discrepancies caused by environmental fluctuations. They also provide excellent long-term stability, reducing the need for frequent recalibration.
Because mass flow meters are highly reliable and offer precise data, they are preferred in modern CNG dispensers and required by many national metrology authorities for commercial fueling.
