ents on metrological management. The chapter briefly introduces fuel dispenser’s metrological management and technical requirements, appraisal related and attentions. Article I Metrological management and technical requirements In accordance with The Law on Metrology of fuel dispenser’s legal management mainly includes following aspects: Model approval, initial approval, sub fuel dispenser sequent appraisal and inspection in operation. Model approval refers to an entire test, examination and assessment as to new model’s entire performance.

Several items reference to the pattern evaluation and sampling testing of mechanical hydraulic section of fuel dispenser as followed: Accuracy testing The testing’s purpose is to define the flow curve and verify the tolerance scope in which the allowed maximum tol
