Fuel dispensers are subject to strict regulation to protect consumers and maintain fair commerce. In most countries, government agencies or standards organizations—such as the National Institute of Standards and Technology (NIST) in the U.S. or Weights and Measures authorities worldwide—certify dispenser accuracy.
These agencies test fuel dispensers using certified reference meters and test tanks. If the dispenser fails, it must be adjusted, repaired, or taken out of service. Many regions also require periodic inspections and tamper-proof seals to prevent fraud.
For gas station owners, ensuring their fuel dispensers remain compliant is not optional—it is a legal requirement. Failure to comply can result in heavy fines, loss of license, or reputational damage.
