Section 2 Installation
Section 2: Installation
General
This section provides installation instructions for the ®
Brooks Sho-Rate
Models 1350G/1355G Flowmeters. Refer to Section 1 of this manual for
connections.
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 notified 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/GlobalSupportCenters
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.
Unpacking
Carefully unpack the meter and inspect it for any damage that may have
occurred during shipment. The flowmeters are shipped completely
assembled and tested. It should not be necessary to tighten or adjust any
of the parts when it is received.
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 All instruments returned to
Brooks also require a Material Safety Data Sheet (MSDS) for the fluid(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:
Recommended Storage Practice
If intermediate or long term storage is required for equipment, as supplied
by Brooks Instrument, it is recommended that said equipment be stored in
accordance with the following:
• Within the original shipping container.
• Stored in a sheltered area, preferably a warm, dry heated warehouse.
• Ambient temperature: 70°F (21.0°C) nominal, 110°F (43°C) maximum,
45°F (7.1°C ) minimum.
• Relative humidity 45% nominal, 60% maximum, 25% minimum.
Telefone: (11) 5035-0920 - E-mail: [email protected]
Av. Dr. Lino de Moraes Leme, 1.094 - Vila Paulista - São Paulo/SP

Section 2 Installation
Upon removal from storage, a visual inspection should be conducted to
verify the condition of equipment is “as received”. If the equipment has
been in storage for an excess of two (2) years or in conditions in excess of
those recommended, all pressure boundary seals should be replaced and
the device subject to a hydrostatic/pneumatic pressure test to 150% of
rated pressure.
Installation
The flowmeter should be mounted within 6° of true vertical. The inlet
connection to the flowmeter is in the bottom end fitting. The connections
are normally horizontal, female NPT. Be sure the piping is adequately
supported to prevent undue strain on the meter.

It is recommended that a final leak test of the system plumbing and meter
be performed before subjecting it to process fluid.

Section 3: Operation
After the flowmeter has been installed in the flow system, it is ready for
operation. An optional built-in needle control valve may be provided to control
the flow through the flowmeter. These control valves are designed
for fine control. Excessive tightening may damage the valve seat and limit its
effectiveness as a control valve. If tight shut-off is required, it is
recommended that a separate shut-off valve should be installed in the line
immediately before the flowmeter.
Flow indication is measured using the center of the spherical float as the
reference point.

Description
T he Brooks bistable limit switches are inductive ring initiators designed to be
slipped over the glass tube. The switch operates as a coil that is inductively
a ctuated by a 316 Stainless Steel or Carboloy ball float. The limit switches can
be set to any desired limit values, by sliding the switch along the metering
tube. The Brooks ring initiators create a highly sensitive, stable latching
signalling on high or low flows, or deviations from a controlled flow.

Alarm Settings
T he minimum setting distance of a switch and a fitting is 8 mm, and the
minimum setting distance between 2 switches is approx. 30 mm, see figure 1.
The standard alarm function is a bistable (latching) function, see figure 2.
O nce the ball float moves inside the inductive switch, the alarm function is
activated, it remains activited, even if the float continues to move towards the
alarm zone, thus leaving the inductive switch. The relay will drop out as soon
as the float crosses the switch from the opposite direction, and moves back the
alarm from the alarm zone into the normal operating range. The actual float
position above or below the alarm switch is precisely indicated.
Figure 3 displays low and high flow alarm settings.
The intrinsically safe power supply/relay unit from Pepperl+Fuchs (KF series)
gives the customer the ability to switch over the alarm function in "Normally
open" or "Normally closed".

Disassembly and Cleaning
It is recommended the user periodically inspect the tube and float, and
clean if necessary. Dirt or foreign materials adhering to the tube and float
may cause inaccuracy and sticking of the float. The metering tube
(Borosilicate glass) and related parts may be cleaned with any solvent
which does not attack glass. To disassemble use the following procedures:
1. Remove the front shield.
2. Loosen the jack screw by turning it counterclockwise with a 5/32” hex
wrench. The tube may now be removed from the meter housing.
3. On meter sizes 1 through 6, the tube, float and float stops may be
cleaned as an assembly or may be diassembled for cleaning. Using a
small hook, remove either Teflon® float stop from the metering tube and
remove the float. Be careful not to chip the tube.
4. Packing seats may now be removed.
5. The needle control valve assembly may be removed by turning the valve
body counterclockwise. The valve seat, stem and packing then may be
removed easily from the valve body for cleaning or replacement.
