What must the totalizer on retail motor fuel dispensers be?

The totalizer on retail motor fuel dispensers must be non-resettable to ensure accurate and reliable measurement of the total amount of fuel dispensed over time. This characteristic is crucial for several reasons.

Firstly, a non-resettable totalizer prevents any manipulation or tampering that could occur if the total could be reset. This ensures that consumers can trust that they are receiving the exact amount of fuel they purchase, and it maintains accountability for the dispenser's performance over its operational life. Retailers also rely on these records for proper inventory management and sales tracking, making it essential that the totalizer provides an unalterable record.

Moreover, regulations and standards in many jurisdictions impose this requirement to protect consumers and maintain fair trading practices. Therefore, having non-resettable totalizers contributes to transparency in transactions and helps uphold the integrity of the fuel dispensing process.
