The VAPORIX system is used to measure and assess the vapour flow of the vapourrecovery systems at filling stations. Please use the system for this purpose only. The manufacturer will not be liable for any form of damage resulting from improper use!The measuring value sensor and the measurement evaluation system weredeveloped, manufactured and inspected in accordance with state-of-the-art technology and with recognised safety rules and regulations. Nevertheless, hazards may arise from the use of these devices. Therefore, please observe the following safety instructions:Do not make any changes,...

Please take note of all national safety and accident preventionregulations as well as all safety instructions in this manual whenworking on the measuring value sensor. To set up and operate the measuring value sensor, the regulations asspecified in the relevant national regulations, as well as those specifiedin the equipment safety laws, and the generally recognised rules of technology and these operating instructions, are decisive. VAPORIX-Flow is subject to construction supervisory certification andis therefore only allowed to be repaired by FAFNIR or by companiesauthorised by FAFNIR. In case...

2.1Installation of the VAPORIX-Flow in the dispenserFor proper assembly of the VAPORIX-Flow, the following installation conditions must be fulfilled (see Fig. 3):The VAPORIX-Flow is fitted in the vapour recovery pipe before the pump andbefore the control valve if one has been fitted.ՕThe unit must be fitted vertically and the inlet section must be at the top. Thedirection of flow has been cast on the casing. The arrow indicating the direction of flow must point from the top tothe bottom. A straight vapour pipe (smooth pipe or corrugated pipe) with a length of atleast 50 mm and an inner diameter...

To guarantee the measuring accuracy of the VAPORIX system, the additionalinstallation measures listed below for the vapour recovery system constellations must be carried out:2.2.1Diaphragm or piston pumps with proportional valve controlThe pulsation is shielded to a large extent by the proportional valve. However, a minimum pipe volume of approx. 50 cm > 3 should be provided. This corresponds toa total pipe length of approx. 80 cm between the sensor and vapour pump, with an inner diameter of 9 mm.2.2.2Double piston pumps with speed controlHere a minimum pipe volume of approx. 50 cm > 3 should...

2.3Connection of the VAPORIX-Flow to the measurement evaluation systemVAPORIX-Control The 8 core connecting cable (4 m long approx. 6 mm) is a fixed part of the measuring value sensor. To make sure that the cable can be guided to the VAPORIX-Control in the head of the dispenser using suitable cable glands, its connecting plug must be disconnected first and then fitted again as shown in the diagram in Fig. 4. > Fig. 4: Pin assignment of the connecting cables for the VAPORIX-Flow ؖ VAPORIX-Control The connecting cable may not be shortened in length. The cable of the VAPORIX-Flow, which is fitted...

Only measuring value sensors of type VAPORIX-Flow which havebeen certified by an approved European test office may be connected. After installing and putting the system into operation for the first time,please also refer to our tips and recommended measures from Chap."Error prevention and troubleshooting". The VAPORIX-Control is only allowed to be operated in atmosphericenvironments. Operation in pressure-enclosed casings such as, e.g.,natural gas dispensers, is not permitted. > VAPORIX-Flow and VAPORIX-ControlPage 15/32 Fig. 7: Connections VAPORIX-Control size="-1">
