Notes

  • These flow meters have the same pin configuration and pinout as the GDS 207 compatible standard pinout flow meters, but they are not compatible with the GDS 207 connector because the pin thickness is larger than what the GDS 207 connector is designed to accommodate.

Other information

Nuova Simonelli / Victoria Arduino

  • Black Eagle Gravimetric machines do not have a flow meter, so will not be compatible.

  • Pulse Jet is preinfusion and will need to be set manually by the tech team. 

La Marzocco

  • Strada does not have a service hole, so no way to feed the main cable out of the machine. Either non-compatible, or a hole needs to be drilled to accommodate the cable. 

  • KB90 Barely has enough clearance for the main cable, plus the adaptor. It can fit through needs improvement from our end, primarily through a slimline version of the adaptor. 

San Remo

  • Cafe Racer has four pole flow meter

Slayer

  • Four pole flow meter

Synesso

  • Four pole flow meter

  • 'S' models internal components are Synesso standard as found in our MVP and MVP Hydra machines.

Unic

  • The group one and two flow meters are further apart than our cable split allows. Manually splitting cable is a short term fix, though refinement required.
