Figure 12: Hazardous locations at the gas station
The current circuit from the hand held terminal to the gas meter is intrinsic
safety due to the fitted safety barrier. Therefore it can be used in the
hazardous area zone 1.
ATTENTION!
Due to safety reasons, the gas meter must be connected
before the nozzle. We do not accept any liability for damage
as a consequence of incorrect connection of the flow meter.
Note:
In order to ensure a long service life of the gas meter,
gasoline must not enter the gas meter under any
circumstances.
