(1) If Hose Positions per Side (column J) is a single digit (i.e., 1, 2, 3 or 4), the model has same number of hoses on both sides of
the dispenser. If two digits are present, the first digit is the number of hoses on Side A (with junction box or primary conduit)
and the second digit is the number of hoses on Side B. If a zero is present in a two-digit number, it means it is a one-sided
dispenser (i.e., 23 in this position represents 2 hoses on Side A and 3 hoses on Side B; 03 represents no hoses on Side A
making it a one-sided dispenser with 3 hoses on Side B; and 20 in this position would describe no hoses on Side B making it
a one-sided dispenser with 2 hoses on Side A).
(2) If the number in the “No. of Grade Selects” column (G) is greater than the “No. of Inlets” column (F), the dispenser is a
blender.
Sealing: The dispenser has a Category 1 wire security seal for the meter, pulser and calibration. The dispenser also has a Category 2
event counter for configuration of gallons to liters and blend ratios. The Helix Series dispenser uses the iMeter [aka Model Global
Hydraulics Module (GHM)] positive displacement duplex meter system or the Wayne Model Xflo positive displacement fuel meter.
The Wayne Integrated Pulsers (WIP) use a physical seal for the meter calibration window. Access to the calibration window is
prevented by a metal pin, which is inserted and secured to a metal clamp. A wire security seal is attached through a hole in the pin.
Each calibration window is sealed separately. The iMeter, iMeter2, and Xflo meters can also be sealed by a wire security seal wrapped
around the calibration window of the pulser and upper part of the meter. (See Figures 1 and 2 for the iMeter and Figures 3 and 4 for
the Xflo).

Category 2 Event Counter for Dispenser Indications: The Helix dispenser also uses the iGEM electronics for information on sealing,
audit trails and blends.
Blending (if applicable) and "gallons to liter conversion" configuration parameters do not have remote configuration capability and are
set at the dispensers. An audit trail in the form of an event counter and a display is provided. The event counter increments once for each
time one or more configuration parameters are changed. For the iGEM, the weights and measures audit trail is accessed by use of the
hand-held remote (see Figure 5). By entering the weights and measures mode, one can view the audit trail and volume metering unit
change counter required by weights and measures officials.

When in the weights and measures mode, the display shows the blend ratio logs and volume metering unit logs for the dispenser. Both
audit trail data and gallons to liters conversion data is obtained by use of a hand-held remote (available at the station being inspected).
Point the remote at the main sales display where the "totals" and "volume" values are displayed. Keep the remote within 12 inches of the
main sales display for proper operation. Operation of the remote is described in Wayne Fueling Systems operation manuals for both
weights and measures officials and service personnel (reference part number 920352).
To Review the Weights and Measures Event Counter for Blending Dispensers:
1. Press ENTER and then press CLEAR twice to access the Weights and Measures mode.
Sale display will show bLEnd rAtioS and the current blend ratios for all the blended products.
Note: If another button is not pressed within 20 seconds, the computer will toggle through the values without interaction from the
remote.
2. Press NEXT repeatedly to view the following:
a. Blend Ratio Change Counters
b. Display Legend, Measuring Units
 LItErs = Liters
 US GAL = U.S. Gallons
 IP GAL = Imperial Gallons
c. Volume Metering Unit Change Counter
3. To exit the Weights and Measures mode, press NEXT repeatedly until it exits.
To Review the Weights and Measures Event Counter for Non-blending Dispensers:
1. Press CLEAR.
2. Read sales money display for n, where n is the unit change event counter.
3. The volume display will show the applicable unit.
Press CLEAR and then press ENTER three to four times to exit the Weights and Measures mode.
Test Conditions: This certificate supersedes National Type Evaluation Program (NTEP) Certificate of Conformance (CC) Number
12-093A2 and is issued to add the iMeter2 to the Helix model RMFD. Testing was conducted with a Helix Model H(N/L)22-22PR
Retail Motor Fuel Dispenser (RMFD) at the Wayne Fueling manufacturing facility with gasoline using NIST traceable one (1) and
five (5) gallon test measures applying a ± 0.3% accuracy tolerance and a 0.2 repeatability tolerance. Additionally, flow rate
adjustments were made on the iMeter, iMeter2, and X-Flo meters based on a review of test data for the flow rates tested from the
Ovation Series (CC Number 02-136A15). Previous test conditions are listed below for reference.
Certificate of Conformance Number 12-093A2: This certificate superseded NTEP CC Number 12-093A1 and was issued to include
blending ethanol fuel blends up to E-85 at the pump. Previous test information and documentation was reviewed from Wayne Fueling
Systems and it is recognized that the upper electronics and X-Flo meter from the Ovation Series NTEP CC Number 02-136A11 are
the same as the Helix Series NTEP CC Number 12-093A1. No additional testing was necessary
Certificate of Conformance Number 12-093A1: This certificate superseded NTEP CC Number 12-093 and was issued to recognize
a change in the company name from Dresser Wayne to Wayne Fueling Systems LLC. Previous test information and documentation
was reviewed. No testing was necessary.
Certificate of Conformance Number 12-093: The emphasis of the evaluation was the design, operation, performance and accuracy
of the Xflo and iMeters in the Helix dispenser. The evaluation was performed on a dispenser at the manufacturer’s facility. The system
was tested at five 10 gpm, three 6 gpm and five 2.5 gpm flow rate for both meter models using gasoline as the product. A one-time test
was conducted due to documentation provided by the manufacturer stating that all the electronics in the dispenser are the same as the
Ovation Series CC 02-136A6.
