A diesel dispenser is a machine that delivers diesel directly from storage tanks to a customer’s storage tanks or to their vehicles. Smaller operations often use diesel pumps to fill up customer’s tanks, but larger operations may use a diesel dispenser. The dispenser uses valves to control the flow of fuel from the storage tanks and into the customer’s tanks. Dispensers with a single pump can handle vehicles and stationary tanks, while those with a double pump can fill two tanks simultaneously. A dispenser is more accurate than a pump because it monitors the amount of fuel being pumped. Dispensers can also be used to meter fuel and to provide discounts for customers who use less fuel than their account allows for. Dispensers that meter fuel are more expensive than pumps but may save money over time due to discounts for less fuel used. Dispensers that meter fuel can also be used to provide fuel for customers who have credit card accounts.
