: Approximately 30 days
Gas Flow Rate Input Signal: 1-5 VDC, 4-20 mA or pulse
Note: at temperatures below 32º F (0º C), conditioning of
the actuation gas supply may be required. Where the
actuation gas supply has a high water content and/or a
low hydrocarbon dew point, additional actuation gas
filtration or heating of the actuation gas supply may be
necessary. Bottled nitrogen can also be used during cold
operating conditions to avoid condensation in the
actuation gas supply line. In addition, operation at
extreme temperatures will affect seal and diaphragm
performance. To prolong the service of seals and
diaphragm, adequate heat should be provided to
maintain an operating environment above 30° F (-1º C).

TheoryofOperation
Operation of the 8300 centers around three primary
components: the Model 8000 pump, the Model
VM-2100 Verometer and the Model N-300G controller.
During normal operation, the Model 8000 pump
injects an exact quantity of odorant at a rate deter-
mined by the N-300G controller. The quantity of
odorant injected per stroke is set using a spacer in
the pump actuation assembly. The rate at which the
pump is actuated is determined by the N-300G controller.
The VM-2100 Verometer serves as a temperature
compensated meter which verifies the amount of odorant
injected by the Model 8000 pump. The N-300G
controller uses an input signal from the Verometer to
determine the amount of odorant that has been
injected, as well as the odorant level within the
Verometer. Once the odorant level falls to a predeter-
mined low level point, the N-300G controller actuates a
solenoid valve which opens the fill valve, allowing the
Verometer to be refilled. Once the Verometer is filled,
the N-300G controller closes the fill valve.
The N-300G controller allows the 8300 system to
operate in either a time-based mode or a proportional-
to-flow mode. In the time-based mode of operation, the
N-300G controller actuates the Model 8000 pump at
a regular time interval preset by the operator.
In the proportional-to-flow mode of operation, the
N-300G controller uses a customer provided gas flow
rate input signal and several operator input values to
calculate the time between strokes of the pump. These
operator input values include the odorant injection rate
(lbs/MMCF or mg/m3) , pump displacement (cc/stroke) ,
and the odorant density
(lbs/gal or g/cc) . The flow input
signal is customer provided by either a flow computer or
other flow monitoring devices. In this mode, the controller
has the capability to distinguish between a low flow
situation and a loss of flow input signal. For systems
with analog inputs, if a loss of flow signal occurs, the
controller automatically defaults back to a pre-selected
percentage of the flow input.
The flow input signal is read by the N-300G control-
ler eight times per pump stroke. These readings are
averaged and the time duration until the next stroke
is then calculated by the controller. The maximum
time between strokes is 99.99 minutes (when gas is
flowing), regardless of the time calculated by the
controller.
Caution:
Excessive tubing lengths should be avoided. Installation
of the NJEX Odorization system should be as close to
the point of injection and Odorant Storage Tank as
possible. Maximum tubing length should not exceed
15' (4.5 meters) with the tubing size maintained as
indicated in this manual. If longer tubing lengths are
required consultYZ Systems Technical Services at;
800.653.9435 or 1.936.788.5593.

Excessive tubing lengths should be avoided. Installation
of the NJEX Odorization system should be as close to
the point of injection and Odorant Storage Tank as
possible. Maximum tubing length should not exceed 15'
(4.5 meters) with the tubing size maintained as indicated
in this manual. If longer tubing lengths are required
consult YZ Systems Technical Services at;800.653.9435
or 1.936.788.5593.
3. Connect the odorant supply source to the odorant inlet
manifold with the recommended 1/4" stainless steel
tubing,
figure 9 . Atank isolation valve should be
incorporated between the storage tank and this
connection,
figure 9 .
4. Connect the regulated actuation gas source, of 75 psi
(5.17 Bar) supplied by the NJEX system owner, to
the NJEX gas filter inlet fitting using a dielectric union,
figure 9 .
Note: in applications where the actuation gas supply
has a high water content and/or a low hydrocarbon dew
point, additional actuation gas filtration or heating of the
8300G system may be necessary. Bottled nitrogen can
also be used during cold operating conditions to avoid
condensation in the actuation gas supply line. Also, an
actuation gas source pressure of 75 psi (5.17 Bar)
should be adequate in most installations.
5. Connect the pipeline port of the odorant discharge
manifold to the pipeline connection using a dielectric
union and check valve,
figure 9 .
6. If a heater option was specified with this odorizer, 120/
240 VAC electricity
refer to the heater wiring diagram,
page 105,
should be connected to the electrical inlet
located on the lower side of the enclosure using 1/2"
conduit and appropriate pack off. Power requirements
for the heater are 1.67A for the 120VAC heater, and
.833A for the 240VAC heater. Each heater is a
thermostatically controlled 200Watt unit,
figure 10 .

Skid System Components
Introduction
The NJEX SkidMount Series of odorization systems is a
total system approach to odorization. These systems
are completely factory assembled, tested, and delivered
requiring only three field connections to be fully
operational. The NJEX SkidMount Systems offer all the
advantages of our standard 8300G Systems plus the
added benefit of an onboard odorant storage tank. The
configuration allows for a total systems approach to
odorization.
The SkidMount Systems come standard with an
electronic level indicator factory connected to the
N-300G controller. The controller has an alarm capability
to indicate when the liquid level in the storage tank has
fallen below a predetermined level set by the operator.
The Systems are available with 20, 60, 120, 250, 500
and 1000 gallon tank sizes.
Skid system primary components of the NJEX-8300G
include the following:
•Skid Mounted Tank a pre-assembled, and tested
Structural steel skid with odorant tank, valve package,
skid piping, and system enclosure.
•NJEX System Enclosure,
figure 11, houses and
protects the; 8000 pump, VM-2100 Verometer,
odorant fill valve, solenoid valve/pneumatic relay
manifold, odorant discharge manifold, N-300 system
controller enclosure, power supply enclosure*, and
bulk odorant filter.
•SPS-12 – Solar Panel Assembly,
figure 11, is
standard equipment for the 8300G and includes a
mounting bracket and a connection cable.Optional
LPS-120/240 may be used in lieu of the solar panel*.
•System Control Enclosure for the N-300G controller.
•Power Supply Enclosure for the battery and
charging system*.

•Bulk Odorant Filter, figure 12, provides primary
odorant filtration between the storage tank and the
NJEX-8300G. The bulk odorant filter is
pre-installed inside the system enclosure attachment
to the odorant source is via a bulk filter manifold
equipped with 1/4" FNPT connection located on the
back of the system enclosure.
•Mechanical Interconnect Cable,
figure 12, provides
the connection between the system control enclosure
and the electrical components located in the mechani-
cal section.
•Expansion Tank,
figure 13, provides a closed loop
system for pressure fluctuations within the Verometer
during the odorant fill and injection cycle.
•NJEX Gas Filter,
figure 13, installed between the
actuation gas regulator and the actuation gas mani-
folds provides a 25 micron coalescent filtration to
insure a clean pneumatic supply.
•Actuation Gas Regulator,
figure 12, provides
additional regulation of supply gas to actuate the
pump.
•Service Tray,
(Not Illustrated), should be installed in
the bottom of the system enclosure, to capture any
drops that may occur during servicing of the odorizer.
