Measuring system (fuel dispenser) description

A complete measuring system consists of one electronic module and one to six hydraulic modules. The hydraulic modules are placed in one or two cabinets (B2B). One electronic module can serve both cabinets, for example a combination of LPG and petrol. If one pump and air separator is serving more than one nozzle simultaneously the total maximum flowrate through these nozzles is limited by the air separator (90 l/min per CPU air separator or 110 l/min for TQP-HS air separator) and the volume sensor (according to "Volume sensor flowrate range under "Measurement range"). For higher flowrate another hydraulic module have to serve the same nozzle. For further information see block diagram in this chapter.

Electronic module function

iGEM and iGEM 2 is an electronic subsystem and it consists mainly of: calculator, indicating device, and keyboard with pre-set. This module can handle up to 6 motors, 6 pulse transmitters (each handling a single equipped or a duplex volume sensor), 12 nozzles, 14 solenoid valves and in case of ATC one temperature compensation module. The electronic module is able to serve up to four customers at a time (called 4 User).

Hydraulic function modules

Measurement transducer function is a hydraulic subsystem and it consists mainly of: volume sensor (single equipped side A, single equipped side B or duplex) and pulse transmitter. In case of ATC (automatic temperature compensation) each volume sensor (iMeter2, Xflo $ ^{\mathrm{TM}} $ ) is equipped with a temperature sensor, all connected to one temperature compensation module.

Pump and air separator function is a hydraulic subsystem and it consists mainly of: Compact Pumping Unit (CPU) including air separator, motor and non-return valve and for LPG a differential valve.

Regulation function is a hydraulic subsystem and it consists mainly of: solenoid valves for flow rate regulation, blending and on/off.

Delivery function is a hydraulic subsystem and it consists mainly of: hoses, nozzles and nozzle switch, this includes also satellite function.

Central pump function is a hydraulic subsystem and it consists mainly of: delivery of air free liquid according to OIML R117-1, item 5.1.3 and security valve.

If the measuring system is equipped with a central pump an external (central) pump is used instead of an internal pump. The external system must comply with OIML 117-1, item 5.1.3 (i.e. it shall be equipped with an arrangement that prevents air to come into the system). The same applies to additive injection.

During verification it shall be possible to verify each volume sensor separately.

Payment or Media platform tested according to OIML R117:2019 (by an OIML test laboratory) to show evidence not disturbing the pump calculator, may be installed in the dispenser, using the dispenser power supply.

Optional equipment and functions

• ATC conversion device (Not for DEF, Windshield liquid and HVO)

• Pre-set of volume or price *****

• Volume totalizer

• Blending (designation only e g 92, 95, 98 octane not 50/50, 70/30 etc)

• Satellite (SAT and MASTER enable button in case of direct sales)

• When using the measuring system to refill aircrafts or helicopters it is allowed to use a water elimination device according to OIML 117-1 5.8.1.2 (E 2019) between meter and hose. For safety reasons it is required to drain the device on a regular base by opening the drain valve. This has to be done by a trained service technician on the measuring system under pressure with closed nozzle. This is to ensure that the hydraulic system is always filled with fuel. The drain valve has not to be sealed.

• Additive injection function for injecting additive liquids to the fuel before the meter. A tank gauge meter is required in the storage tank for additive liquid to avoid injection of air into the fuel. See requirements for central pump function.

If additive liquid is injected before the air separator, the additive is not subject to-OIML

requirements.

Integrated equipment and functions not subject to legal metrology control

Vapour recovery system with vapour pump, regulating proportional valves and an electronic board (for example Bürkert control board, Dover Ivory power pump control or Dover Global VR) connected to the calculator CPU-board. The vapour flow is controlled by the electronic board or the calculator CPU-board. Optionally also a vapour recovery monitoring system consisting of a Vapour meter and belonging Intrinsic safe barrier may be used. Means for vapour recovery must not influence the accuracy of measurements such that the maximum permissible error is exceeded.

For DEF, heating is installed to keep the liquid from freezing. As an option a pump circulates liquid downstream the meter between deliveries, through the coax hose to a container (max volume 2,55 litre in circulation system) to avoid freezing.

Rated operating conditions

Measurand

Volume of liquid fuel expressed in litre. If ATC conversion device is included (not for DEF, Windshield liquid and HVO), the volume at base condition (15 $ ^{\circ} \mathrm{C} $ ) is displayed. The calculations are based on OIML R63 (API/ASTM 54B) except for petrol/ethanol mixtures where Verfahren 1 according to PTB-1.5-40520004 dated April 11, 2011, is used.

The ratio between maximum and minimum flow rate should be at least 10 for single quality and 5 for blending quality, DEF, Windshield liquid and LPG.

+5 $ ^{\circ} \mathrm{C} $ to $ +55^{\circ} \mathrm{C} $ for iGEM printer

Interfaces and compatibility conditions

Interface for vapour recovery systems.

Communication between fuel dispenser and other parts of a measuring system (e g POS-systems) using one of the following non-reactive interfaces is evaluated and approved. (This does not imply that the complete self-service arrangement fulfils the requirements of OIML R117):

Most protocols do not include "unit", for example "volume @ 15 $ ^{\circ} \mathrm{C} $ ". Instead this has to be handled during set up of the station controller and dispensers. It must be possible for the measuring system to print "@ 15 $ ^{\circ} \mathrm{C} $ " on the ticket.

When the dispenser is a part of a self-service arrangement the following requirements have to be fulfilled:

• The communication between the dispenser and the self-service device/devices has to be through one of the interfaces/protocols listed above.

• The connection has to be verified by the installer so the metrological data are presented in a way, whether it is an indicated, printed or memorized result, that meets the requirements of OIML R117.

Control of the measuring tasks of the instrument in use

For dispensers with ATC the volume at base condition is displayed in normal working mode.

Alternative 1: When verifying the dispenser as a "black box", the delivered volume measured in a volume standard $ V_{t\text{ref}} $ is converted to volume at base condition $ V_{15} $ using $ V_{15} $ ref $ = V_{t\text{ref}} $ x VCF where VCF, volume correction factor, is based on the quality and temperature t of the liquid.

Alternative 2: When the display is showing ATC Revision and CRCs press the CRC button and the W&M-mode is active for 30 minutes (or until next push on the CRC-button) displaying $ V_{t} $ $ V_{1 5} $ temperature t, product and density. A test well (inner diameter 4 mm) can be used for the reference temperature sensor.

A thermometer well is installed upstream the meter, to be used during verification

Identification Software for iGEM

The metrological software is identified by the checksum (W&M CRC value), which can be accessed by pressing the CRC button on the iGEM calculator CPU board. (Upon this also the program CRC values and software version number are indicated at the dispenser display.)

Program CRC value (AD67)

W & M CRC value (555F)

Identification Software for iGEM 2

The metrological software is identified by the checksum (W&M CRC value), which can be accessed by pressing the CRC button on the iGEM 2 calculator CPU board. The software versions and CRC values are shown in the following sequence:

• The first indicating on the sales volume display after the CRC button is pushed is the Firmeware version of the dispenser application.

• After a few seconds the display will change and show the CRC for complete program both LR and non LR is included.

• After an other few seconds the display will change again and the amount and volume display will show the W&M-CRC for the LR part of the code and the UPD will show LrCrC. It will looks like this:

• Then will the display change again and show the Bootloader Firmware version.

• After that the Bootloader Firmware CRC. The UPD will show b CrC

• When the display change again it will show the ATC information

Amount display: W&M CRC value on board temperature module
