Appendix B
Dispenser Compatibility
Following this description is a sample FuelMaster
®
Dispenser Compatibility listing. This listing
was compiled, and is periodically updated, to keep our customer’s (users and technicians)
informed of the interface capabilities of FuelMaster
®
FMUs. The listing is an Adobe Acrobat file
with an integrated date:
Dispenser_Compatibility_090310.pdf. The listing contains the manufacturer
and model of many fuel dispensers which have been interfaced to FuelMaster
®
fixed site FMUs. It
identifies whether the dispenser may be directly connected to an FMU, or if it must be connected with an
Electronic Dispenser Interface Kit. If you want the most up-to-date information from the dispenser
compatibility listing, call Syn-Tech’s Customer Satisfaction Center at 800-888-9136, ext. 1500, and ask
for the latest copy to be e-mailed or fax’d to you.
The opening paragraph is a disclaimer. Although we have established a good raphor with most of the
dispenser manufacturers, they are not obligated to inform us when a change or new product is
introduced. As such, changes to fuel dispensers may occur before they show in the listing. Do not
assume this listing will always provide the most current information regarding newly introduced or
changed dispensing equipment.
Dispensers which have more than one fueling hose must have a means for controlling individual fueling
hoses. For example, hoses cannot be individually controlled in a dual hose single product dispenser with
no solenoid valves. In this example, solenoid valves would have to be added to the dispenser.
The first column in the listing is the Manufacturer/Model of the dispenser. Every specific model number
may not be listed if all models within a series are compatible (example: Bennett 3911 is included in a
3900 series listing).
The second column, Mechanical/Electronic, is a simple description of the display. Mechanical would be
on a mechanical dispenser where the quantity or cost is shown on revolving wheels. Electronic would be
a digital LED or LCD display.
The third column, Commercial/Retail, identifies whether the dispenser has a cost display. A Commercial
dispenser will only display quantity. A Retail dispenser will display quantity and cost.
The fourth column, Direct Interface, will have a check mark (√) in it if the FMU may be connected directly
to the fuel dispenser to attain individual hose control and pulses.
The fifth column, Electronic Dispenser Interface*, will have a check mark (√) in it if an Electronic
Dispenser Interface Kit must be used to interface the FMU to the dispenser. Usually this only applies to
retail fuel dispensers subject to periodic Weights & Measures inspections. The asterisk (*) is there to bring
attention to a note. OINKs (abbreviation for Opto-Isolators) were developed by Syn-Tech Systems several
years ago to interface electronic dispensers (for commercial/fleet purposes) when there was no Electronic
Dispenser Interface Kit. Where the OINKs provide an interface sufficient for commercial or fleet
applications, they do not possess the accuracy necessary for retail (Weights & Measures) applications.
DoD and Classic FMUs will not interface electronic dispensers.
The sixth column, Require Pulse Option, has a check mark (√) if the manufacturers literature identifies
pulsers as optional equipment. Every dispenser interfaced to an FMU must deliver pulses.
The seventh column, Require OINK*, will have a check mark if an Opto-Isolator has been developed for
the application. The asterisk (*) brings attention to the note stating OINKs do not have sufficient accuracy
for retail applications.
