Flow meter connection variations

	GDS 207 compatible, standard pinout	GDS 207 compatible, alternate pinout	Three quick connect 2.8x0.8mm	Two quick connect plus ring terminal	2.54 pitch four pin header
Example images	Image Added	Image Added		Image Added
Pinout	Image Added	Image Added	Image Added	Image Added	Image Added
Specification	Three 2.8x0.51mm pins in DIN 43650 form C 9.4mm configuration, signal on centre pin	Three 2.8x0.51mm pins in DIN 43650 form C 9.4mm configuration, ground on centre pin	Three 2.8x0.8mm pins in DIN 43650 form C 9.4mm configuration, signal on centre pin	Two 2.8x0.8mm pins, plus one M4 ring terminal (ground)	Single row 4 circuit 2.54 pitch pin header
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 width is larger than what the GDS 207 connector is designed to accommodate.

Other information

...

• 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

• Standard Gicar, though alternate pin out adapter required. 

• Modbar, FB70  and strada models use the ‘lug’ adaptor that Rancilio use. 

• 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 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.

...

• Cafe Racer has four pole sensor

Rancilio 

• Requires the Two terminal plus ground lug adaptor. 

Slayer

• 4 pole flow sensor

• Standard connection which does not require a cable adaptor

• Four pole sensor will so will need confirmation data is accurate. 

Synesso

• 4 Pole Flow sensor. 

• Standard connection which does not require a cable adaptor. Flowmeter pins are thicker and may require quick connects(TBC)

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

Unic

• Standard connection though does require the alternate pinout adaptor. 

• the 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. 

La Cimbali

• Four pin header adaptor required. 

Kees Vander Westen

• Standard Flow sensor, so no adaptor required.
