INTRODUCTION

A.

GENERAL.

These

instructions

are

for

servicing

the

Series

7886

High-Capacity

and

Series

7887

Meter

Registers

designed

and

manufactured

by

the

Veeder-Root

Company,

6th

Avenue

at

Burns

Crossing.

P.O.

Box

Altoona,

When a vertical

bar | appears

adjacent

to

text

or

illus

trations,

information

has

been

added

or

changed

at

the

last

issue date.

Note:

Consult

Veeder-Root

on

any

unusual

application,

installation

or

possible

modification

of

this

basic

design.

Every

Meter

Register

is

thoroughly

tested

at

the

Veeder-Root

factory

and

by

the

meter

manufacturer

when

installed

on

the

meter.

However,

like

any

precision

mechanism,

it

requires

periodic

care

to

ensure

maximum

service.

This

manual

is

for

use

in

areas

where

factory

rebuilding

facilities

and

adequate

exchange

stocks

are

not

readily

accessible.

Where

manufacturer's

replacement

stocks

are

available,

it

is

important

that

no

attempt

be

made

to

repair

any

meter

register

defective

within

the

terms

of

the

warranty

as

by

doing

so,

the

warranty

is

void

and

the

user

is

deprived

of

the

protection

provided

by

the

warranty.

It

is

recommended

that,

when

possible,

meter

registers

be

replaced

and

the

defective

unit

returned

to

the

meter

manufacturer.

Note:

See

Section 6 for

complete

Damage

Claims

and

Warranty.

IMPORTANT!

The

instructions,

photographs

and

drawings

in

Sec

tions 4 and 5 are

based

on

the

Series

7887

Meter

Register.

With

the

exception

of

an

additional

count

ing

wheel,

the

Series

7886

High-Capacity

Meter

Register

is

physically

similar

and

the

same

proce

dures

should

be

followed.

DESCRIPTION

A.

GENERAL.

1.

Physical.

The

Series

7887

Meter

Register,

Figure

1,

displays

a

running

account,

final

total

and

accumulated

total

of

the

quantity

of

liquid

product

delivery.

Contained

in

a4"x

10"

diecast

enclosure,

individual

delivery

data

is

displayed

on

five

3/4"

high

figures

while

totalizer

information

is

recorded

on

eight 1 /8"

high

figures.

Reset

of

the

Meter

Register

is

accomplished

through a reset

knob

on

the

right-hand

side

of

the

unit.

2.

Operational.

The

Meter

Register

is

operated

by a drive

shaft

connected

to a group

of

gears

on

the

gear

plate

which

converts

the

drive

revolutions

to

the

appropriate

ratio.

The

output

bevel

gear of the

group

drives a bevel

gear,

Figure

5,

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

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.

on

the

which

converts

The

bevel

gear

of

the

assembly.

In

rotating,

this

shaft

drives

agear

Revolutions

are

then

In

this
