Causes and Precautionary Measures of Measurement Out-of-tolerance in Verification Cycle of Fuel Dispenser
In the verification of fuel dispensers,the measurement of dispensers in the verification cycle often exceeds the tolerance.Measurement out-of-tolerance refers to the deviation between the measured result and the actual refueling amount when the dispenser is being metered.This phenomenon may be caused by factors such as damage to the metering elements within the dispenser,excessive sediment accumulation,or improper operation.Based on this condition,this paper analyzes the causes and precautionary measures of measurement out-of-tolerance in the verification cycle of fuel dispensers in detail,for reference.
