4 Receipt of Shipment
When you receive your equipment inspect the
outside of the packing case for damage which may
have incurred during shipping. Damage incurred
during shipment is the responsibility of the car-
rier and is not part of the factory warranty. If the
packing case is damaged, notify the local carrier
immediately.
If the package is in good condition remove the en-
velope containing the packing list and carefully re-
move the equipment and all components included
in the shipment from the packing case. Inspect for
damaged or missing parts, referring to the packing
list, and prior to discarding the packing material.
If Items are missing from your shipment, contact
your sales representative. Your sales order number
will be required.
5 Return of Equipment
If the equipment must be returned to the factory
for repair or replacement, a Returned Materials
Authorization (RMA) must be included with the
components.
RMA forms may be obtained from your sales repre-
sentative or from the Product Service Department.
In addition to the RMA, a Material Safety Data
Sheet and a Decontamination Statement must be
included with Items being returned to the factory.
A Decontamination Statement is included in the
back of this manual.
If the equipment is removed from service it must
be thoroughly drained and neutralized before it is
packed for shipment. Care must be taken to en-
sure that product removed from the equipment is
disposed of in accordance with all applicable local,
state and federal regulations.

6 Storage
Brodie International instruments are precision de-
vices and should be handled and stored with care.
They should not be subjected to rough or improper
handling or stored in an environment where mois-
ture, extreme temperatures, or foreign material
can damage the meter.
The inlet and outlet connection covers should
remain on the instrument until the unit is ready for
installation.
If extended storage is required it is recommended
that the instrument be placed in an environmental-
ly controlled warehouse. If this is not possible the
instrument should be stored in a waterproof lined
wooden box. Desiccant packs should be taped to
the inside of the instrument end connections be-
fore they are sealed to reduce the effect of humidi-
ty on the equipment and accessories. Caution must
be used to ensure desiccant packs are removed
prior to installation.
Depending on the storage time it may also be pref-
erable to use a compatible corrosion inhibitor.
If the injection block is removed from service for
an extended period of time it should be flushed
with a light oil before being placed into storage.

8 Functional Operation
The Brodie Addpak injector block consists
of a 304 stainless steel block machined and
assembled with a positive displacement oval gear
meter, Asco solenoid, isolation and control needle
valves on the inlet and outlet, a strainer, and check
valve. Additionally, a quick coupler is included for
calibration. Compact design and low cost provide
the ideal solution for chemical additive injection
regarding petroleum terminals and pipelines.
Compared to other types of injectors, Brodie’s
AddPak Injector
Block minimizes leak points; All components are
built and assembled into the block.
The AddPak injector block is a slave injector,
typically controlled from a PLC, Terminal Automa-
tion System or Electronic Preset. If the application
requires a smart controller, please consult the
factory. The AddPak as standard does not include
the necesary electronics to pace the injector,
accumulate totals, or provide alarms.
Controller
The controller as referenced above will send an
AC voltage to the solenoid. This will energize the
coil and allow flow through the block. As flow
passes thru the block, the oval meter will send
pulses proportional to flow volume back to the
controller. When the preset volume is met, the
controller will terminate the AC power to the sole-
noid, the valve will close, and flow will cease. This
cycle is repeated every time the controller sends
AC voltage to the solenoid. Standard AC voltage
is 115 VAC with options for 230 VAC or 24VDC
solenoids available. The User should select a
controller with alarms for conditions with excess
additive or no additive flow. The controller should
discontinue loading until the problem is resolved
and the alarm has been reset. The user can consult
Brodie for assistance in selecting the appropriate
controller.
9 Mounting
The AddPak Injection block can be mounted in any
orientation provided the oval gears remain in a
horizontal position. The inlet and outlet connec-
tions can be vertical, horizontal, or inclined. To
ensure the gears are in a horizontal position, the
sesnor and solenoid should be facing the installer,
rather than facing up or down.

11 Solenoid Input
The Add Pak Injection Block has a single control
input. The single input is connected to the coil of
the solenoid valve. The solenoid valve is normally
closed and when powered the coil is energized and
the valve opens and remains opened until power is
removed. The standard voltage for solenoid coil is
115VAC. Optionally the solenoid coils with 230VAC
or 24VDC can be supplied.
12 Sensor Output
The AddPak Injection Block is equipped with
a Hall-Effect pickoff. It is mounted in close
proximity to the oval gears. Each oval gear has
two rare earth magnets embedded and sealed
on the face of the gear. As flow passes through
the block, the oval gears rotate in direct pro-
portion to the volume, and the sensor changes
state as each magnet passes the sensor. When
the gear and magnet are directly in line, the
pickoff changes from off, to on, momentarily,
then back off. This operation occurs as each
magnet passes the sensor. The K Factor for the
meter is approximately 5400 pulses per gallon.
This K factor is the starting point in the field.
Field calibration is necesary to calculate the true
K factor under specific process conditions which
depend on required flow rate and chemical in use.
K factor data is transmitted into the control device.
Brodie offers a calibration kit with dry break quick
connections and a graduated cylinder. The custom-
er is responsible for performing calibration.

Page 16/24 IOM AddPak R01
13 Wiring
Solenoid
The solenid wiring from the controller to the coil
should be a minimum of #18AWG. The AC and DC
wiring should run in separate conduit. It is high-
ly recommended that the user contract a local
certified electrician to run and terminate the wir-
ing in accordance with all govermental codes for
the area. The solenoid coil produces and inductive
load to the controlling device. Please consult with
the manufacture of the controller regarding this.
Meter Sensor
The sensor wiring can be either a three or four
conductor, #18-22 AWG shielded instrument cable.
Use the Belden number 6502FE or similar. Shield
should terminate at the controller to a DC com-
mon or a specifically assigned termination. Do not
terminate shields wires to an AC earth ground. Do
not terminate shield at sensor. Isolate the shield at
Meter Sensor and tape off.
Meter Sensor: Pulse Signal Output
The AddPak Injection Block meter sensor
output is an un-sourced, open collector, transistor
output. The white sensor wire is connected to the
transistor collector. The emitter of the transistor
is connected to the black wire, or DC COMMON
connection; The term “un-sourced” means that
no voltage is applied to the output from with-
in the sensor. It must be pulled to a “high” or
“on” or “true” state by voltage supplied from an
external source. The sensor electronics then drives
the collector “low” or “off” or “false” with each
pulse transmitted. The output is NOT driven high
internally with the sensor. The industry common
scheme allows the sensor to drive external equip-
ment supplied by its own internal transmitter pow-
er. There must be a common connection between
the DC negative of the sensor supply and the DC
COMMON of the signal pulse counter. Refer to the
wiring diagram at the end of this manual for spe-
cific connection details.

IOM AddPak R02 Page 17/24
15 Thermal Relief
Brodie offers both an injection point kit with a
blocking solenoid and thermal relief kit for appli-
cation where no contamination is required. This
is normally used for dyes and markers. Since the
injector block has a blocking solenoid and the
injection point kit has a blocking solenoid it is
necessary to relieve any thermal pressure build up
between them. The thermal relief kit is installed on
the inlet and outlet of the injector block. The injec-
tion point kit is installed in the field by the user or
their contractor.
14 Process Fluid Connections
General
The process fluid inlet and outlet connections are
3/8” FNPT. The inlet and outlet are marked in the
front of the AddPak. The inlet pressure must be
higher than the outlet to ensure proper injection.
Fluid Inlet and Outlet Piping
The piping from the additive pump to the AddPak
must be sized to ensure adequate flow to meet the
demand for injection. Remember to consider how
many injectors will be operating and the total flow
required to meet that demand. Distance from the
additive pump and the injectors is another thing
to consider when determining the pipe size. The
minimum tubing size to reach the maximum flow
of 3 GPM is typical 1/2”. Larger tubing or pipe may
be required based on the viscosity of the additive.
The outlet tubing from the AddPak to the point of
injection is 1/2”. We recommend using stainless
steel tubing. A check valve and isolation valve is
recommended at the point of injection into the
process line. This will prevent product flow from
contaminating the additive when the injector is in
the idle state. The check valve should be a postive
shutoff spring close check. The check valve should
be selected to open with positive pressure of 1 to
10 PSI. If you have multiple injectors piped to one
injection point then a check valve and isolation
valve should be installed for each injector.
