Essential Instructions

Read this page before proceeding!

Brooks Instrument 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 Brooks Products.

• Read all instructions prior to installing, operating and servicing the product. If this instruction manual is not the correct
manual, please see back cover for local sales office contact information. Save this instruction manual for future reference.

• If you do not understand any of the instructions, contact your Brooks Instrument 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.

• T o ensure proper performance, use qualified personnel to inst all, operate, update, program and maintain the product.

• When replacement parts are required, ensure that qualified people use replacement parts specified by Brooks Instrument.
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.

Pressure Equipment Directive (PED)

All pressure equipment with an internal pressure greater than 0.5 bar (g) and a size larger than 25mm or 1" (inch) falls under the
Pressure Equipment Directive (PED). The Directive is applicable within the European Economic Area (EU plus Norway, Iceland
and Liechtenstein). Pressure equipment can be traded freely within this area once the PED has been complied with.

• Section 1 of this manual contains important safety and operating instructions related to the PED directive.

• Meters described in this manual are in compliance with EN directive 97/23/EC module H Conformity Assessment.

• All Brooks Instrument Flowmeters fall under fluid group 1.

• Meters larger than 25mm or 1" (inch) are in compliance with category I, II, III of PED.

• Meters of 25mm or 1" (inch) or smaller are Sound Engineering Practice (SEP).

ESD (Electrostatic Discharge)

Handling Procedure:

1. Power to unit must be removed.

2. Personnel must be grounded, via a wrist strap or other safe, suitable means before any printed circuit card or other internal
device is installed, removed or adjusted.

3. Printed circuit cards must be transported in a conductive container . Boards must not be removed from protective enclosure
until immediately before installation. Removed boards must immediately be placed in protective container for transport,
storage or return to factory .

Comments

This instrument is not unique in its content of ESD (electrostatic discharge) sensitive components. Most modern electronic
designs contain components that utilize metal oxide technology (NMOS, SMOS, etc.). Experience has proven that even small
amounts of static electricity can damage or destroy these devices. Damaged components, even though they appear to function
properly, exhibit early failure.

The Brooks

®

BM Series Flowmeters, hereafter called flowmeters, are
positive displacement meters that measure extremely low flows of clean
liquid with high accuracy . The flowmeter generates an electrical signal
proportional to flow for use with a wide variety of electronic
instrumentation.

The flowmeters have incorporated the oval rotor principle into its design.
This has proven to be a reliable and highly accurate method of measuring
flow . Exceptional repeatability and high accuracy over a wide range of
viscosities and flow rates are features of the flowmeters.

The low pressure drop and high pressure rating means the flowmeters are
suitable for both gravity and pump (in line) applications.

Capacities (See T able 1-1): Capacities,
For capacities with higher viscosity, (Refer to Table 1-8)

Section 2 Installation

BM Oval Series

This section contains the procedures for the receipt and installation of the
flowmeter . Do not attempt to start the system until the flowmeter has been
permanently installed. It is extremely important that the start-up procedures
be followed in the exact sequence presented.

When the instrument is received, the outside packing case should be
checked for damage incurred during shipment. If the packing case is
damaged, the local carrier should be notified at once regarding his liability .
A report should be submitted to your nearest Product Service Department.

parts.

If intermediate or long-term storage is required equipment, as supplied by
Brooks Instrument, it is recommended that the equipment be stored in
accordance with the following:

a. Within the original shipping container.
b. Stored in a sheltered area, preferably a warm, dry, heated warehouse.
c. Ambient temperature of 70° F (21° C) nominal, 109° F (43° C)

maximum, 45° F (7° C) minimum.

d. Relative humidity 45% nominal, 60% maximum, 25% minimum.

Upon removal from storage a visual inspection should be conducted to
verify the condition of equipment is "as received".

2-5 T ransit Precautions

Instrument must have been purged in accordance with the following:

All flow instruments returned to Brooks requires completion of Form
RPR003-1, Brooks Instrument Decontamination S tatement, along with a
Material Safety Data Sheet (MSDS) for the fluid(s) used in the instrument.
Failure to provide this information will delay processing by Brooks
personnel. Copies of these forms can be downloaded from the Brooks
website www.BrooksInstrument.com or are available from any Brooks
Instrument location listed above.

To safeguard against damage during transit, transport the meter to the
installation site in the same container used for transportation from the
factory if circumstances permit.

2-6 Installation

Section 2 Installation

BM Oval Series

To provide for optimum system performances the following guidelines
should be observed:

1. Before use, confirm the fluid to be used is compatible with the meter .

2. The flowmeter must be installed so the shafts of the rotors are
horizontal, never vertical or “on end”. Severe damage to components
may be the result, (See Figure 2-1).

3. A mesh strainer should be installed upstream and adjacent to the
flowmeter to protect it from foreign matter such as dirt, pipe scale,
or welding splatter.

2-7 Pre-Operation Procedures

Section 2 Installation

BM Oval Series

(Refer to Table 2-1 for strainer size), ( See Figures 2-5 and 2-6).

4. Valves should be installed to facilit ate removal of the flowmeter and
strainer , (See Figures 2-4 and 2-5).

5. Install the flowmeter on the discharge side of a pump whenever

possible.

6. Before installing the flowmeter, wash and clean the inside of the pipeline

with compressed air or steam. This is particularly important on new
pipelines.

7. Remove the protective covering from the flowmeter end connectors

before installation.

8. When making connection to the flowmeter make certain that no foreign

materials enter flowmeter body .

9. Ensure that the meter is installed so that the flow of the liquid is in the

direction of the arrows embossed on the meter body .

10. Refer to Figures 2-2, 2-3 or 2-4 for electrical connections.

1. After the flowmeter has been installed, slowly allow the liquid to flow in

bypass section of a horizontal installation or the main line of a vertical
installation. This will clear the line of any foreign p articles.

2. Test the system for leaks.

3. Check the strainer for foreign material, after the first 50 gallons/200 liters

check periodically , particularly if the flow rate decreases.

NOTE: Foreign particles in the main line may cause damage to
the flowmeter .
