Step 1: Location/Orientation
The instrument may be located anywhere in the process line,
as long as the following conditions are met:
• Beforeoperation,youmustbeabletostopowthrough
themeter.Duringthezeroingprocedure,owmustbe
stoppedcompletely,andtheowmetersensortubemust
befullofprocessuidtoachieveanaccuratezero.
• Duringoperation,theowsensortubemustbefullof
processuid.
• Ambient temperature must remain between 0° and 60°C
(32°F and 140°F).
• The instrument (cable connections, wiring compartments
and/orconduitopenings)shouldbeaccessibleforservice.
Horizontal Down Mounting
Preferred mounting orientation
for most LIQUID applications:
• Sensor tube DOWN
• Horizontal pipeline
Horizontal Up Mounting
Preered mounting for
most GAS applications:
• Sensor tube UP
• Horizontal pipeline
Vertical Mounting
Orientation for LIQUID
applications where entrapped
gas may occur:
• Flag mount
• Vertical pipeline

Receipt of Equipment
Whentheequipment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notiedatonce
regarding his liability. A report should be submitted to the nearest
BrooksInstrumentlocationlistedontheGlobalServiceNetwork
page on our website: brooksinstrument.com/service-support
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.
Return Shipment
Priortoreturninganyinstrumenttothefactoryforanyreason,visit
our website for instructions on how to obtain a Return Materials
Authorization Number (RMA #) and complete a Decontamination
Statement to accompany it: brooksinstrument.com/service-support
All instruments returned to Brooks also require a Material Safety
DataSheet(MSDS)fortheuid(s)usedintheinstrument.Failure
toprovidethisinformationwilldelayprocessingoftheinstrument.
Instrumentmusthavebeenpurgedinaccordancewiththe
following:
Equipment Receipt and Return Procedures
Aftertheowmeterorowcontrollerhasbeeninstalledinthe
system it is ready for operation.
Meter: Themeterwillprovideaowsignalproportionaltothe
fullscaleowofthedeviceasindicatedonthedevicelabel.
Controller: Youmustprovideasetpoint/commandsignaltothe
controller. The controller will read the setpoint signal and will
automaticallyadjustthevalvetotheappropriatepositionto
achievethedesiredowandwillprovideaowsignal
proportionaltothefullscaleowofthedeviceasindicatedon
thedevicelabel.
Step 4: Zeroing Procedure
To assure measurement accuracy, the instrument must be
zeroed to the operational installation conditions:
• Apply power to instrument for approximately 45 minutes to
reachastablethermalconditionpriortoapplyingow.
• Flowtheprocessuidintotheinstrumentandallowsu󰀩cient
time for the sensor to reach normal operating temperature.
• Closetheshuto󰀨valvedownstreamtoeliminateanypressure
 di󰀨erentialacrosstheinstrument.
• AfterconrmingaNOowcondition,pressthezeroingbutton
for at least 3 seconds
• Zeroing button is located on the side of the instrument’s
housing.
• The zeroing process takes approximately 60 seconds. Status
lightwillashred.
• A solid Green LED means a successful zero.
• A solid Red LED means an unsuccessful zero.
Note: If solid Red LED is indicated, recycle power and repeat
