1-4 Optional Equipment
Screwed-in needle valves
Needle Valves in brass and 316 SS can be mounted to the instrument in inlet
or outlet tting.
We strongly advise not to use solenoid-valves as these can cause pressure
shocks and damage to glass tubes.
Screwed-in ow controllers
Brooks self-contained ow controllers are constant differential regulators
with built-in ow control needle valve. The internal diaphragm-actuated
control valve is positioned by the incoming uid pressure on one side of the
diaphragm, and outlet pressure + spring action on the other side. Variations
in the supply and/or discharge pressure disturb the balance of forces on the
diaphragm, causing the control valve to close or to open, thus maintaining
a xed differential across the manual ow regulating valve. The series 8800
controllers are designed for all liquid and gas ows with constant downstream
pressure. Series 8900 controllers are designed for all liquids and gas ows
with constant upstream pressure.

Instrument must have been purged in accordance with the following:
All ow instruments returned to Brooks requires completion of Form
RPR003-1, Brooks Instrument Decontamination Statement, along with a
Material Safety Data Sheet (MSDS) for the uid(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 the instrument against transportation damage, it is
recommended to keep the instrument in its factory container until ready for
installation.
Section 2 Installation
Warning
Before returning the device purge thoroughly with a dry inert gas such as Nitrogen
before disconnecting gas connections. Failure to correctly purge the instrument
could result in re, explosion or death. Corrosion or contamination may occur
upon exposure to air.

2-6 Installation
The model GT 1300 can be installed as follows:
a Carefully remove any material which could have been used to protect the
instrument for damage during shipping.
b The indicator must be installed with the inlet at the bottom and the outlet
at the top, and must be installed as near vertical as possible to maintain
indicator accuracy.
c It is strongly recommended to install a by-pass piping arrangement around
the meter. By-pass piping permits the meter to be isolated from the low line
for servicing or cleaning.

Section3: Operation
3-1 Start-Up
After the owmeter has been properly installed in the process, it is ready for
operation. When initiating ow, slowly open the valve to avoid a ow surge.
By-pass is a help in bringing the ow on smoothly. Avoid starting a pump to
supply the owmeter without the use of a valve upstream of the owmeter.
3-2 Reading the ow rate
Rate of ow is indicated by reading the increments, etched on the scale,
mounted adjacent to the metering edge of the oat.

Section 4: Maintenance
4-1 General
There is no routine maintenance to be performed on the GT 1300 glass tube
owmeter. If meter operation is affected by defective parts, refer to Section 5,
Parts Lists for available replacement parts. No instructions are required for the
assembly or disassembly of either model since the procedures are self-evident.
Model 1306 owmeters require little maintenance except routine cleaning.
It is neccessarry to remove the owmeter from the line for tube and oat
cleasing. The tube and oat may be cleaned with a soft absorbent swab. To
disassemble the owmeter proceed as follows:
a. Remove the front and rear window shields.
b. Remove four (4) screwa connecting the bottom end tting to the side plate.
c. Carefully pull the end tting and tube away from the side plates and top
tting. DO NOT cock the tube when removing it from the top tting.
d. Remove the polycarbonate sleeve surrounding the ow tube.
e. Remove the oat from the tube.
f. Using a suitable solvent, carefully swab and ush the inside of the metering
tube. Clean the oat and blow dry all parts thoroughly.
Section 4 Maintenance
Warning
Products in this manual may obtain metal or elastomeric seals, gaskets, O-rings or
valve seats. It is the "user's" responsability to select materials that are compatible
with their process and process conditions. Using materials that are not compatible
with the process or process conditions could result in the Meter or Controller
leaking process uid outside the pressure boundary of the device, resulting in
personnel injury or death.
It is recommended that the user check the Meter or Controller on a regular schedule
to ensure that it is leak free as both metal and elastomeric seals, gaskets, O-rings
and valve seats may change with age, exposure to process uid, temperature,
and/or pressure.

SEAL COMPTABILITY
Caution
Do not allow the oat to fall out of the metering tube. A damaged oat will affect
the accuracy of the meter. Be careful not to break the tube by pulling on it at an
extreme angle or apllying excessive force.

Reassemble the owmeter as follows:
a. Carefully install the oat in the tube with the metering edge up.
b. Carefully hold the tube (with oat installed), sleeve, and end tting, and
push the tube into the top tting.
c. Tighten the four (4) side plate screws in place.
d. Install the front and rear windows.
4-2 Service information
Should the equipment require repair, contact the nearest sales/service ofce.
It is important that servicing is performed only by trained and qualied service
personnel. If the equipment is not properly serviced, serious personal injury
and/or damage to the equipment could result.
Section 4 Maintenance
Notice
Anytime the meter is removed for service, new O-rings should be installed in
both the inlet and outlet end tting.
Warning
Pressure test the meter before returning it to service. Hydrostatic pressure testing
should be performed by qualied personnel or serious injury and/or damage to
the equipment can result.
