SB-100 Series Meter
Bennett Type 40 Meter
• Manufactured from 1939 to 1990
• Great meter in LEADED fuels
• Experienced unacceptable calibration drift in UNLEADED
Fuels
• Expensive to manufacture
Bennett SB-100 Meter
• Introduced in 1991
• Initial problems due to contaminants in fuel (dirt, sand, and
fine powder abrasives resulting from gasoline refining
processes at some refineries) that tended to scratch
surfaces of the valve plate and the distributor. This problem
was particularly prevalent in sandy, desert environments.
This problem was fixed in 1994.
Bennett SB-100 Meter Today
• Early problems completely resolved
• Long Life Meter when Bennett specified proper filtration is
used.
• Quality as good or better than Wayne or Gilbarco meters.
Bennett SB-100 Meter—Determining the Age of the Meter
• Identified by date code on either an adhesive metallic tag, metal Part
Number/Serial Tag, or adhesive white tag.
• Serial #3E624788 shown at bottom right….3E is the date code signifying
manufacturing in March (month 3), 2003 (E = 2003). Current models use
the white adhesive tag (see below).

Bennett SB-100 Meter Improvements
• Changed from softer aluminum valve plate to hard
stainless steel for superior wear characteristics
• Changed to a sleeve style bearing to better resist fuel
contaminants
• Changed Diaphragm to stronger material to resist
rupture
• Changed Distributor from aluminum to a composite
material for superior sand and dirt resistance to
improve calibration stability
Older Styles - Brown or Red
Old Distributor (Dark Charcoal
Color) - Hard Coated Anodized
Aluminum Material.
0 Bumps
Old Distributor (Shiny Black
color) - Teflon Impregnated
Molded Resin Material.
1, 2 & 3 Bumps
Current Style - Black
Current Distributor (Shiny Black
color) - Teflon Impregnated
Molded Resin Material.
4 Bumps
Current Distributor has four small protrusions (bumps) located in the above position (white color added
for photographic clarity). You can reach in the outlet of the meter and turn the meter by hand and feel for
these four bumps to confirm that you have the current distributor. Older distributors had 0, 1, 2 or 3
bumps.
SB-100 Series Meter
Computerized Testing Program
• Every SB-100 Meter is tested against a master flow meter for
both slow flow and fast flow accuracy.
• The test fluid used is a nonflammable solvent whose viscosity is
between gasoline and standard diesel. (Every meter should be
checked and recalibrated when dispensers are installed
according to the provisions of Bennett’s Dispenser
Installation Manual.)
NOTE: Due to variations in installation and in products
dispensed, owners are responsible to ensure that meters are
calibrated following dispenser installation. Bennett is not
responsible for the calibration that must be done at the
time of dispenser installation.
• A software program determines whether the meter passes the
stringent calibration accuracy requirements.
• Mechanical Calibration meters may be adjusted within certain
parameters to pass our testing.
• eCal meters must be within testing parameters or they are
rejected.
Rejection of any meters whether mechanical
adjustment or eCal type is extremely rare.
• Test data is recorded for each meter according to the meter
serial number.
• The test data is used for various quality measurement purposes
including trend analysis.
• The master test meter is calibrated every 30 days, or immediately if
our trend analysis detects a suspected problem with the master
meter.
• The calibration tools for testing the master meter are verified and
certified for accuracy once per year by the State of Michigan’s
regulatory agency that has adopted the standards from the U.S.
National Institute of Standards, National Type Evaluation Program
(the national metrology regulatory agency). Calibration tools may be
certified more often than once per year if data trend analysis points to
any suspected problem with the tools.
What happens if a meter fails at the final testing station?
It is extremely rare that a meter fails our final test. If one does
fail, a senior production associate carefully disassembles the
meter and attempts to determine the cause of the failure. If the
cause of the failure is an assembly mistake, the meter is reassembled correctly and must pass a second final test. If the
senior production associate cannot determine the cause of the
failure, the meter is passed to our engineering group for
examination including measurement of parts to ensure that all
parts are meeting our strict tolerance specifications. All meters
must pass our testing stations before they are used in a
customer product. Meters that cannot pass our testing station
are scrapped.

SB-100 Series Meter
The Bennett SB-100 is a precision instrument. Flatness tolerance specifications for distributor, valve,
and counter valve are 5 light bands (50 millionths of an inch). To ensure the continued integrity of the
precision parts during the life of the meter, proper filtration before the meter is essential. Filters protect
the meter, the pumping unit (if present), flow control solenoids, the nozzle, and ultimately the customer’s
automobile components. Filters should be replaced or cleaned on a regular basis or anytime the flow
rate has dropped by a noticeable amount. Bennett dispensers or any dispensers using Bennett meters
should NEVER be operated without proper filtration. Failure to maintain the filtration in the Bennett
dispenser voids the warranty protection offered by Bennett. Under no circumstances should the
meters be exposed to filtration larger than 70 Micron.
—Good filtration practices extends the life of the Bennett hydraulic components.—
