: 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).

Theoryof Operation
Operation of the 6300G centers around three primary
components: the Model 6000 pump, the Model VM-1000
Verometer and the Model N-300G controller.
During normal operation, the Model 6000 pump injects
an exact quantity of odorant at a rate determined 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-1000 Verometer serves as a temperature
compensated meter which verifies the amount of
odorant injected by the Model 6000 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
predetermined 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 6300G 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 6000 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:UTION:
UTION:UTION:
UTION:
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
6300G 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 106,
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,

SkidSystemComponents
Introduction
The NJEX SkidMount Series of odorization systems is a
total system approach to odorization. These systems
are completely factory assembled, tested, and
shipped requiring only three field connections, to be
fully operational. The NJEX SkidMount Systems
offer all the advantages of our standard 6300G
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-
6300G 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; 7000F pump, VM-1100 Verometer,
odorant fill valve, solenoid valve/pneumatic relay
manifold, odorant discharge manifold, and the
N-300 system controller enclosure.
•*SPS-12 – Solar PanelAssembly,
figure 11,
is
standard equipment for the 6300G and includes a
mounting bracket and a connection cable.
*Optional LPS-120/240 or DC power may be used
in lieu of the solar panel.
•System Control Enclosure for the N-300G controller.
•*Power Supply Enclosure for the battery and
