2. OPERATION

2.1 GENERAL

The Meter-register is operated by a drive shaft connected to a group of gears on the gear plate, which

converts the drive revolutions by the appropiate ratio. The output bevel gear of the group drives a

bevel gear which is connected to the drive shaft and clutch assembly. In rotating this shaft drives a

gear on the clutch assembly which in turn drives a gear on the right (unit) wheel assembly.

Revolutions are then accumulated on the wheels. In addition, this rotating shaft also drives the

bracket group connected to the accumulative totalizer shaft, thus both displays are driven from the

same source assuring accurate recording of information. During the reset operation, the clutch is

disconnected from the drive shaft, a shutter moves into place covering the display wheels and reset

fingers engage heart-shaped cams on the individual wheels to move them back to a zero position. In

addition, a set of anti-topping fingers engages the wheels to prevent jamming. At the completion of

reset, the display wheels will read all zeros, and the shutter will rise to the normal operating position.

The clutch will engage the drive shaft to transfer the information from the next delivery. The totalizer

wheels will be unaffected by this reset operation, thus displaying an accurate measure of the

accumulated totals of many deliveries.

2.2 OPERATION

Operate and reset meter-register as follows:

1. to reset indicating wheels to zero, turn reset knob, on right side of register, clockwise.

CAUTION DO NOT TURN COUNTER CLOCKWISE

2. do not start delivery unless shutter is in full open position. If numerals on indicating wheels are not

in full view, resetting operation has not been completed, in which case, turn reset knob clockwise

untill shutter disappears and reset knob returns to its normal position.

3. MAINTENANCE

3.1 GENERAL

The meter-register is fully lubricated and properly adjusted at manufacture. However, periodic

cleaning and lubrication are required. Judgement of the intervals at which the meterregister requires

such service must necessarily be left to the individual user, due to varying conditions of service.

Under normal conditions this will be at least once a year, or after each 2.5 million units of measure

delivered, which ever comes first.

3.2 METER REGISTER REMOVAL

Remove the meter-register from the meter by removing the bolts holding the two together. Bolts are

located at the bottom of the Meterregister.

3.3 DISASSEMBLY PRIOR TO CLEANING

Remove the meter-register from its housing as follows:

1. Remove the bolts securing the cover (if present) to the top of the housing. These bolts are hex

head and are located at the four corners of the bottom of the housing. Remove the cover and

lever.

2. Remove the three button-head bolts securing the meterregister to the housing. Remove the meter-

3. Remove the screws securing the gear plate to the bottom of the housing. Remove the gear plate.

3.4 CLEANING

CAUTION: DO NOT USE A WIRE BRUSH

1. Wipe bezel crystal with a clean lint-free rag.

2. Flush wheels with clean Savasol or equivalent solvent. Blow out surplus solvent with compressed

air.

3. If the wheel faces are dirty, gently clean with a clean lintfree rag, dipped in solvent.

4. Clean the gears on the gear plate by flushing or with a brush dipped in solvent. Blow dry with

compressed air.

5. Clean housing by dipping, flushing or brushing with solvent. Blow dry with compressed air.

3.5 INSPECTION

A periodic inspection of the entire meter-register, housing and gear plate is required to make sure that

they function properly, parts are in place, and no binding or excessive side-to-side motion of shafts

occurs. A check list on such procedures follows:

1. Check the following shafts for excessive side-to-side motion. Note: remove the meter-register from

the housing before checking and shaft freedom.

a. wheel shaft

b. anti-topping finger group shaft

c. reset finger group shaft

d. clutch group shaft

e. pinion shaft.

2. Temporarily instal the gear plate and meter-register in the housing and check for proper

engagement and freedom of movement of:

a. all gears on gear plate

b. output bevel gear on gear plate with the bevel drive gear on drive shaft.

c. 57 tooth gear on clutch assembly with gear on right wheel assembly.

d. gear drive shaft, with gear train that operates tha totalizer, and gear connecting the drive

train to the totalizer.

3. Check spacing 00.010 to 0.020 inch (0,25 to 0,50 mm) of brake above the right hand wheel.

4. Rotate drive shaft by hand to see that unit operates freely and then reset, checking for proper reset

and shutter action, adjust pointer after reset as required.

5. Check all screws, retaining rings and groove pins to see that they are tight and seated properly.

3.6 LUBRICATION

3.6.1 RECOMMENDED LUBRICANTS

NOTE:

Anderol products are manufactured by Lehigh Chemicals, Nuoder Division, Tennoco-Chemicals, Inc.

Chestestertown, Md.

OIL

Anderol L-401-D or equivalent with a temperature range of -65° to +300°F (-54° to +149 °C).

GREASE

Anderol L795 or equivalent with a temperature range of -65° to +300°F (-54° to +149 °C).

NOTE:

All lubricants used in the register must be of a type which remains fluid over the full temperature

range to which the register will be subjected. Also, they should not oxidize or dry out leaving a

gummy or perceptible residue.

If the Anderol lubricant is not available, a substitute with equivalent properties may be used. To assist

fieldmen in obtaining suitable lubricants for the meter-register and ticket printers, the following list

showing equivalent lubricants has been prepared:

OIL: AEROSHELL FLUID NO. 3

ARGEOYLE ARTIC OIL LIGHT

REGENT SPINTEX OIL 60

CASTROL HYSPIN - 40

GREASE: AEROSHELL 14

ESSO BEACON - 325

3.6.2 POINTS TO LUBRICATE

OIL

All points indicated as (oil) on figure l should be lubricated with oil as described above. This includes

all shaftst studs, and bosses on which a moving part bears.

GREASE

Grease should be applied to all points indicated as (grease) on figure 1.

NOTE:

The oil and grease should be applied with a srnall brush to make certain that all areas will be properly

lubricated. In this manner, the amount of lubricant being used will be controlled easier.

3.7 ASSEMBLY AFTER LUBRICATION

1. Install the gear plate on the bottom of the housing and secure with screws.

2. Install the meter-register in the housing and secure with three button-head bolts.

3. Install the cover (if present) and lever and secure with bolts.

3.8 METER REGISTER INSTALLATION

Mount the meter-register on the meter and secure the two with bolts removed in paragraph 3.2.

4. GEAR PLATE

A gear plate can be mounted at the bottom of the Meter-Register in order to obtain several read-outs

on VAF Positive Displacement flowmeters (e.g. litres, m

). Two ratios are used, namely 1:1 and 10:1.

6. WARRANTY CONDITIONS

1. Without prejudice to the restrictions stated hereinafter, the contractor guarantees both the

soundness of the product delivered by him and the quality of the material used and/or delivered for

it, insofar as this concerns faults in the product delivered which do not become apparent during

inspection or transfer test, which the principal shall demonstrate to have arisen within 12 months

from delivery in accordance with subarticle 1A exclusively or predominantly as a direct

consequence of unsoundness of the construction used by the contractor or as a consequence of

faulty finishing or the use of poor materials.

1A. The product shall be deemed to have been delivered when it is ready for inspection (if

inspection at the premises of the contractor has been agreed) and otherwise when it is ready

for shipment.

2. Articles 1 and 1a shall equally apply to faults which do not become apparent during inspection or

transfer test which are caused exclusively or predominantly by unsound assembly/installation by

the contractor. If assembly/installation is carried out by the contractor, the guarantee period

intended in article 1 shall last 12 months from the day on which assembly/installation is completed

by the contractor, with the understanding that in this case the guarantee period shall end not later

than 18 months after delivery in accordance with the terms of subarticle 1A.

3. Defects covered by the guarantee intended under articles 1, 1a and 2 shall be remedied by the

contractor by repair or replacement of the faulty component either on or off the premises of the

contractor, or by shipment of a replacement component, this remaining at the discretion of the

contractor. Subarticle 3A shall equally apply if repair or replacement takes place at the site where

the product has been assembled/installed. All costs accruing above the single obligation described

in the first sentence, such as are not restricted to shipment costs, travelling and accommodation

costs or disassembly or assembly costs insofar as they are not covered by the agreement, shall be

paid by the principal.

3A.If repair or replacement takes place at the site where the product has been

assembled/installed, the principal shall ensure, at his own expense and risk, that:

a. the employees of the contractor shall be able to commence their work as soon as they have
