Certified calibration ensures that the mass flow meter in a CNG dispenser measures gas accurately according to national and international legal standards. Without proper calibration, customers may be overcharged or undercharged for fuel.
Calibration involves comparing the dispenser’s readings with a reference standard under controlled conditions. This process identifies measurement drift and corrects it to keep accuracy within approved tolerances. Regulatory agencies typically mandate calibration every year or after major maintenance.
Maintaining certified calibration boosts customer trust, ensures fairness in transactions, and protects station operators from legal penalties or disputes over inaccurate fueling data.
