CNG dispensers use high-precision mass flow meters to measure the exact amount of compressed natural gas delivered. These meters are designed to handle high-pressure conditions without losing accuracy.
During each transaction, the dispenser’s control system continuously calculates flow rate and mass to ensure fair billing. Regular calibration keeps the meter within government-approved accuracy limits.
Because CNG is sold by mass, not volume, accurate metering is essential. Modern dispensers maintain excellent reliability even under temperature and pressure fluctuations.
