Descriptive annex
Flow tests is done according to OIML R139:2018-2 table 9 which do not include determination of the actual flowrate range but the dispensed mass. Due to the construction and the function of the measuring system it is not possible to adjust the flow before and during the measurement. Therefore, the flowrate is not determined and verified.

Other essential components:
Piping, valves, pressure control valve, breakaway valve, safety valve, hose and nozzle.
Interfaces:
The calculating/indicating device communicate to POS system using one of the following protocols when initialising the measurements.
TW (Gilbarco Two wire)
TW is a point to point communication.
IFSF (Epsilon LonWorks)
IFSF is using an Epsilon local operating network.
Sealing:
The calculating/indicating device is sealed by a physical seal behind a cover plate.
The flow sensor and the transmitter are sealed by a physical seal according to manufacture sealing plan.
Name plate and type plate shall be sealed or by other means permanently attached.
Identification plate:
The measuring system, shall bear a permanent, non-transferable, and easily readable identification plate or label giving the following information:
manufacturer's trade mark/corporate name;
year of manufacture;
type designation / model number;
accuracy class;
type approval number and (area allowed for) verification marks, according to national legislation;
serial number of the measuring system;
The minimum measured quantity (MMQ) (shall be permanently visible on the front of the indicating device.)
The following metrological and technical characteristics, where applicable, shall be provided either on the identification plate, or may be visible either permanently, or on demand on the indicating device, as appropriate:
measuring range (minimum flow rate, $ Q_{\mathrm{min}} $ , and maximum flow rate, $ Q_{\mathrm{max}} $ );
maximum pressure of the gas in the refueling station gas storage, $ P_{\mathrm{st}} $;
maximum fast fill pressure of the gas-fuelled vehicle, $ P_{v} $;
