Gear Plate Selection Guide Gear plates are used to convert a meter’s output to the desired unit of measure; for example, 1/10 or whole US gallons, 1/10 or whole imperial gallons, liters, cubic meters, barrels, pounds, etc. To facilitate the changing of the unit of measure desired, the gear plate is attached to the base of the large numeral counter with two screws. To make proper gear plate selection, you will need to know: 1. Meter size 2. Unit of measure required 3. Packing gland ratio 4.
Packing Gland Ratio Three packing gland ratios are available to permit achieving the proper RPM of the register unit wheel (right hand wheel). Pattern Codes The Pattern Code number diagram shows five general gear assembly configurations that can be constructed using the basic gear plate and swing arm assemblies. Patterns 10, 30, and 50 can be used with a mechanical temperature compensator.
Gears Gear Limitations Available Gears • • Standard gears range from 30 to 69 teeth inclusive. Other gears available are listed below. • Adjuster Reduction: 3.997:1 at 25% setting. Two Gear Ratio Capacity: Pattern 10 must equal 118 total teeth. Idler Arm Capacity: Patterns 20, 30, 40, & 50: 114 teeth maximum, 72 teeth minimum. C-D A-B E-F B A X D C X F E No.
Formulas for Computing Gear Plate Ratios Nb x Rc = R1 Pg x W x Ra R2= 7. R2 = Dn divided by Dr, which is the actual ratio. Dn Dr 8. Dn = Driven gear. 1. Nb = Revolutions per gallon of the blocking rotor. 9. Dr = Driving gear Meter Model Nb Value M-5 (old style) ------------- 4.0790 M-5 (new style) ---------- 12.2370 MS-5 ----------------------- 12.2370 M-7 --------------------------- 5.555 MS-7 ------------------------- 5.555 M-10 ------------------------- 5.555 M-15 ------------------------- 2.
