“A” Series:Proven meters with improved flexibility.

Instrumentation compatibleRegulatory demands are requiring audit

trails on smaller loads. Recognizing this

need, we made sure that the “A” Series

meters were fully compatible with all

volume and temperature-integrating

instruments available today.

EZ-VU adjustment systemAdjusting our meters just got even easier!

The EZ-VU adjustment system consists of a

larger port opening, a clear Lexan port

cover, and an adjustment tool with an

integral light. The larger opening, combined

with the illuminated tool, lets you see where

the displacement and speed screws are

located. The Lexan port seal, through which

the adjustment tool passes, allows

adjustment and proving without removal

and replacement of the hand-hole plate.

Easier to installThe ‘ET’ Easy Turn design allows 2 to 3

times more wrench swing than the

competition – as much as a full 120

degrees (see table below) for meters

mounted directly against a wall – making

the Schlumberger 675A, 800A, and 1000A

‘ET’ gas meters the easiest and safest to

install in North America.

Schlumberger “A” Series meters dispel old

notions about large diaphragm meters.

Compact size can co-exist with long life.

Weight can diminish without compromising

durability. Diaphragm meter accuracy is

available across the complete range, from

small to large commercial metering

applications.

Schlumberger “A” Series meters give

you the physical size you need, without

compromising our tradition for highly

accurate meters that are a good value. This

customer-driven design makes for easier

handling in the shop and the field. The “A”

Series retrofits to any meter set within its

capacity range, eliminating the need for

“installation specific” meter inventory.

Compact without compromiseDespite their leaner profile and reduced

weight, the “A” Series meters still offer the

long-term durability you’ve come to expect

from Schlumberger’s big diaphragm meters.

Utilization of the time-tested and well-

proven seamless diaphragm continues, as

does the wearless orbital valve and

lubrication-free bearing design. These

features ensure accuracy throughout the life

of the meter, keeping overall measurement

costs low.

Accuracy. Reliability.

Durability. These

attributes come from a

focus on continuous

improvement. In our

commitment to research

and development,

Schlumberger has

retooled and redesigned

our commercial

diaphragm meters to

provide the safest,

easiest to install gas

meters available today.

400A:The compact performer for lightcommercial metering

movement assemblies, carrier wire brackets

and diaphragms. That means less inventory

to carry and more flexibility in installation.

The top and top gasket are the same on the

new 400A as on our previous 400 meter.

Ideally suited to light commercial and high-

capacity domestic metering requirements,

the Schlumberger 400A offers:

• 45% reduction in size from our previous

model

• interchangeable parts with our 250 and

400 models

• lightest, narrowest 400-class meter on

the market

• fewer moving parts than any other

400-class meter

• performance that exceeds ANSI B109.1.

Schlumberger’s 400A meter is the most

compact and lightweight 400-class meter

on the market today. Maintaining the use of

a wearless orbital valve, single convolution

diaphragms, and lubrication-free bearings,

the 400A delivers maximum initial and

sustained accuracy.

Designed to fitAvailable with either Sprague standard 625⁄32”

(172mm) or 81⁄4” (210mm) center-to-center

hubs, and with a reduced height of 1422⁄32”

(374mm), the 400A can replace any existing

400-class meter with no need for expensive,

time-consuming piping rework.

The 400A utilizes several proven

components from Schlumberger’s 250-class

meter, including side covers, side cover

gaskets, non-TC and TC lower main

675A, 800A, 1000A:Diaphragm accuracy for higher capacitymetering applications

feature a top-mounted index drive for full

instrumentation compatibility. In addition,

the index can be rotated to 180˚ for

installations where it is more convenient to

install the meter backwards.

Schlumberger 675A–100A meters offer

these advantages for commercial metering

applications:

• reduced size and weight compared to

previous models

• fully compatible with today’s volume and

temperature-integrating instruments

• retrofit to any meter set within

the capacity range

• performance that exceeds

ANSI B109.2.

The larger members of the “A”-series

combine accuracy and long life in a

compact meter. Thanks to modern

engineering and production techniques, the

Schlumberger 1000A, for example, weighs

28 percent less than our previous 1000-

class meter. Its height has been cut by 29

percent, creating a leaner, tighter meter.

This new smaller size adds up to big

advantages in easier shipping, handling and

installation – at just 19” (483mm) from base

to hub, these meters can be applied

wherever capacities of 675-1000 ft3/h (18-

28m3/hr) are needed.

With the size reduction, all

Schlumberger 800A and 1000A meters will

retrofit into any of your current meter sets.

Costs are controlled by eliminating

inventory tracking of different-sized meters

in the same capacity range.

Easier to install, easier to useThese high performance meters offer

advantages after installation, too. They all
