A suitable mounting location for the Flow Gateway near the espresso machine (usually under the counter)
Nb. The supplied flow meter cables are 3 meters long, so depending on the routing of the cable within the espresso machine, this allows for installing the Flow Gateway approximately 1.5-2 meters away from the espresso machine
One, or two if a Wi-Fi network is used, AC power outlets near the location of the espresso machine (usually under the counter):
- The first is for the Flow Gateway power supply
  Nb. The Flow Gateway power supply cable is 1 meter long
- The second is for the Wi-Fi to Ethernet adapter
  Nb. The TP-Link TL-WA850RE may not fit in a power outlet adjacent to another plug. It is 66mm wide, and extends 85mm above the centre of plug and 25mm below the centre of the plug
If a machine has non-standard flow meters we can't guarantee connectivity and the installer will have to assess on a case by case basis based on the connector type and pinout
