Introduction

JJF1001-2011 "General metrological terms and definitions", JJF1002-2010 "National metrological verification procedures The JJF1059.1-2012 “Evaluation and Expression of Uncertainty in Measurement” together constitute the basis for the revision of this regulation. This regulation refers to OIMLR117.2019 "Non-aqueous Liquids" issued by the International Organization of Legal Metrology (OIML). The relevant contents of GB/T 9081-2023 "Motor Vehicle Fuel Dispenser" are combined with the measurement technical requirements of my country's fuel The actual use of oil dispensers, the current status of the industry, the revision of JJG 443-2015, the main measurement technical indicators Compared with JJG 443-2015, this regulation has the following major technical changes, in addition to editorial revisions. --- Added indicator device, minimum volume variable, software identification, legal related software part, cycle stability etc. terms and definitions; --- Changed the terms and definition; --- Changed the description of the working principle of the fuel dispenser; --- Changed the nameplate requirements; --- Increased the requirements for random files; --- Increased structural type requirements; --- Changed the requirements for indicating devices; --- Deleted the requirement to display digital altitude in indicating devices; --- Added requirements for fuel dispenser software identification; --- Changed the inspection method of the self-locking function; ---Added encoder requirements; --- Deleted the requirements for atmospheric pressure, power supply voltage and power supply frequency under the verification conditions; --- Increased safety protection requirements; --- Changed the requirements for flow points and number of measurements for initial and subsequent verification; --- Added the requirements for adjusting the indication error; --- Deleted Appendix C and adjusted the content of automatic calibration device to the main text. The previous versions of this regulation are as follows. ---JJG 443-2015; ---JJG 443-2006; ---JJG 443-1998; ---JJG 443-1986. Fuel dispenser verification regulations (trial implementation)

3 Terminology and units of measurement

3.1 Terminology The following terms and definitions apply to this practice. 3.1.1 Fuel dispenser A dynamic measurement system of liquid volume used to refuel a vehicle. 3.1.2 Self-locking function When the pulse equivalent or refueling amount of the fuel dispenser is abnormal, the fuel dispenser will automatically lock and cannot refuel. A component that converts the continuous flow of fuel into mechanical rotation and transmits it to the encoder. 3.1.4 Encoder Converts the mechanical rotation of the flow measurement transducer into a pulse signal or digital signal and transmits it to the control mainboard part. Receive the pulse signal or digital signal transmitted by the encoder, generate refueling data according to the legal measurement control requirements, and The control microprocessor transmits the data to the indicating device for display, and has the functions of data communication, processing, storage, control, etc. 3.1.6 indicating device A component that is solely controlled by a monitoring microprocessor and can continuously display refueling data.
