Essential Instructions
Brodie Meter Co., LLC designs, manufactures and tests its products to meet many national and
international standards. Because these instruments are sophisticated technical products, you must
properly install, use and maintain them to ensure they continue to operate within their normal
specifications. The following instructions must be adhered to and integrated into your safety program
when installing, using and maintaining Brodie Meter Co., LLC products.
• Read all instructions prior to installing, operating, and servicing the product. If this instruction
manual is not the correct manual, telephone 1-912-489-0200 and the requested manual will be
provided. Save this instruction manual for future reference.
• If you do not understand any of the instructions, contact your Brodie representative for clarification.
• Follow all warnings, cautions, and instructions marked on and supplied with the product.
• Inform and educate your personnel in the proper installation, operation, and maintenance of the
product.
• Install your equipment as specified in the installation instructions of the appropriate instruction
manual and per applicable local and national codes. Connect all products to the proper electrical
and pressure sources.
• To ensure proper performance, use qualified personnel to install, operate, update, program, and
maintain the product.
• When replacement parts are required, ensure that qualified people use replacement parts
specified by the manufacturer. Unauthorized parts and procedures can affect the product’s
performance and place the safe operation of your process at risk. Look-alike substitutions may
result in fire, electrical hazards, or improper operation.
• Ensure that all equipment doors are closed and protective covers are in place, except when
maintenance is being performed by qualified persons, to prevent electrical shock and personal
injury.
• Before opening the flameproof enclosure in a flammable atmosphere, the electrical circuits must be
interrupted.
• The ATEX approval applies to equipment without cable glands. When mounting the flameproof
enclosure in a hazardous area, only flameproof cable glands certified to EN 50018 must be used.
• If replacement of screws that secure the gear housing, sensor housing, UMB, cover, or electric
register is necessary, they must be replaced with M6-1 X 16 mm hex socket head cap screws.
The screws must be made of 304 stainless steel and have a minimum tensile strength of 125 KSI.
• When installing this equipment, bolting must conform to the requirements of ASME B16.5
paragraph 5.3 and to the material requirements of ASME B16.5 Table 1B. Gaskets must conform
to the requirements of ASME B16.20.
• It is the customer’s responsibility to ensure thatipiping or other attachments connected to the
BiRotor Meter do not place adverse stresses on the BiRotor Meter. The design of the BiRotor
Meter has not been assessed for the effects of traffic, wind or earthquake loading.
• It is the customer’s responsibility to provide fire prevention measures and equipment per local
regulations.
• The BiRotor Meter has been designed without allowance for corrosion. The customer should
implement a periodic inspection and maintenance program to ensure that no part of the BiRotor
Meter’s pressure-retaining components has been subjected to corrosion.
• Use of this equipment for any purpose other than its intended purpose may result in property
damage and/or serious personal injury or death.

i
 Warning
Do not exceed the maximum working pressure of equpment as stamped on the
nameplates. It is the customer’s responsibility to install this equipment in a system that
provides adequate over-pressure protection.

NOTICE
Lines should be flushed thoroughly to rid piping of potentially damaging foreign material
such as welding bead, pipe scale, etc. before the equipment is placed in service. A strainer
of proper size should be installed upstream of the valve to protect it from the introduction
of foreign material.

A Decontamination Statement is included in

the back of this manual (see Appendix A).

If the meter is removed from service it must be

thoroughly drained and neutralized before it is
packed for shipment. Care must be taken to
ensure that product removed from the meter is
disposed of in accordance with all applicable 4
local, state and federal regulations. Note: Place
the meter on the inlet flange to completely drain
the meter of fluid.

The flanges should be sealed to keep residual
fluid from leaking out of the meter during
transport. The type of flange seal required will
vary with the form of transportation used.
Contact the carrier for specific instructions.

The meter should be securely mounted on a

wooden skid for shipment. The original container
or a solid wooden box should be used to protect
the exterior of the meter.

meter from excessive flow rates.
12. A strainer should be installed upstream of
the meter to protect it from the entrance of
foreign material which might damage the
measuring unit. A regular schedule should be
set up to clean the strainer basket to prevent
foreign material from filling and rupturing the
screen. Pressure gauges installed on either
side of the strainer will show the differential
pressure across the strainer. High differential
pressure may cause the basket to rupture,
permitting large quantities of foreign matter to
enter the meter suddenly. This would result in
stoppage of the meter and require it to be
disassembled and cleaned.

rotor/measuring unit assembly:
1. Restrict rotor movement by placing a folded
cloth rag between the teeth of the timing
gears.
2. From the input end of the measuring unit,
remove the screw (Item 17), washer (Item 10),
and pulse wheel (Item 23).
3. Remove end plate screws (Item 17) opposite
the rotor gear end. Using two flat screwdrivers

 Figure 4.4 Measuring Unit Reassembly
Caution
When pressing in bearings, press only on the
outer race. Using the press on the inner race of
the bearing may cause the bearing or races to
deform.

3. Check that bearings are pressed in properly.

Bearing races should be flush with the bottom
of the end plates. If additional pressing is
required, pressing on the outer race of an old
bearing on top of the new bearing will assist in
proper seating.
4. Attach one end plate. Align dowel pins and
holes and tap into place using a plastic or
rubber mallet. Secure the end plate using the
screws (Item 17).
5. Lubricate the O-Rings (Item 11) on the rotor
shaft with grease or oil. Mesh the rotors
together. Rotors should be held with the
tapered shaft ends facing the end plate
containing two dowel connections. While
keeping the rotors properly meshed and even,
insert the rotors into the measuring chamber.
With a quick thrust, insert the rotors the rest
of the way. If the rotors do not seat properly
into the end plate, use a plastic or rubber
mallet to drive the rotors the rest of the way
in.

Orientation of the rotor and gear placement is

important. The right hand rotor has an “R”
inscribed at the end of the rotor base. The left
hand rotor has an “L” inscribed at the end of the
rotor base. Likewise rotor gears are inscribed
with “R” and “L”. Match common inscriptions for
proper installation.

21. Initiate system startup. Reference Section
3.0 Storage, Installation and Operation.

4.7 Clearance Setting

Meter accuracy and service life depends on
proper clearance settings. It is important the
rotors turn freely within the measuring unit and
that they make no contact with each other at any
point.

With the measuring unit exposed and the hex

nuts of both rotor shafts finger tight:
1. Restrict the rotation of the rotor gears with a
folded cloth rag. Tighten the gear of the right 14
hand rotor 15 - 20 ft./lbs.
2. Loosen the hex nut of the left hand rotor.
3. Place a 0.005 inch shim in front of and behind
the tooth of the left hand rotor14141414141414
as shown
below. Once the shim is in place (and the
rotor movement restricted by the folded rag)
tighten the rotor hex nut.
4. Remove the shim. Check for proper clearance
by rotating the rotors. Listen for sounds of the
rotors touching. Rotors should turn freely and
not make contact at any point.
5. Repeat procedure until proper rotor/gear
clearance is established.

5.0 Troubleshooting
Table 5.1 has been provided to aid in basic troubleshooting. Disassembly procedures are covered
in Section 4.0 Maintenance. If the flowmeter is found to be in need of repair, it is important that
servicing be preformed by trained and qualified service personnel and it is recommended the user
contact the Brodie Meter Co., LLC Repair Department.
