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.

•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 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.

Section 1 Introduction

BM Oval Series

1-1 Purpose

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.

1-2 Description

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.

1-3 Specifications

Capacities (See Table 1-1): Capacities,

For capacities with higher viscosity, (Refer to Table 1-8)

Installation 2-1 General

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.

2-2 Receipt of Equipment

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.

Remove the envelope containing the packing list. Carefully remove the instrument from the packing case. Make sure spare parts are not discarded with the packing materials. Inspect for damaged or missing parts.

2-3 Recommended Storage Practice

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".

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 Statement, 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.

2-5 Transit Precautions

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.

Vertical Installation

Horizontal Installation

Do Not Install Meter This Way

Note: Rotor shafts must always be parallel to the ground

2-6 Installation

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.

Strainer Recommendations

Model	Max Partical Size	Strainer Size
BM04	0.011" (0.28mm)	60 Mesh
BM07	0.011" (0.28mm)	60 Mesh

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

4.Valves should be installed to facilitate 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.

2-7 Pre-Operation Procedures

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 particles.

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.
