2. System Components
The primary components of the DynaPak 2010L
Sampling System are illustrated here.

DynaPak 2010L Gas Sampler
The DynaPak 2010L Sampler is a pipeline
mounted system which uses the pneumatically
operated, positive displacement DynaPak 2000
pump, the Z-65 timer/controller, the YZ filter/
regulator and a low power solenoid valve to obtain
gas samples from pipelines between 10psig (0.69
Bar) and 1500 psig (103.4 Bar).
The 2010L provides three modes of operation:
A. Time-based sampling: in this mode of
operation, the 2010L extracts a gas sample from
the pipeline at regular time intervals. The volume
of the sample is set by the operator using the
volume adjustment feature of the DP-2000 pump.
The Z-65 controller operates as a recycling timer,
periodically energizing a low power solenoid valve.
Energizing the solenoid valve allows actuation gas
to stroke the DP-2000 pump. The rate at which
this occurs is a function of operator input. Two 10
position switches are used to set the off time
interval. The number of times the solenoid output
is activated is recorded by the onboard LCD stroke
indicator.
B. Time-based sampling with the optional
YZ differential pressure switch (DPS-2): this
mode of operation is similar to the time-based
sampling mode, except that the DPS-2 converts a
differential pressure signal to an electrical signal
that the Z-65 timer uses to determine if flow is
present in the pipeline. In effect, the DPS allows
the Z-65 timer to shut off when flow stops in the
pipeline, and when flow starts again, the ability to
start-up and resume operation.
C. Proportional-to-flow sampling:
in this mode of operation, the Z-65 counter
operates as a dividing counter. The Z-65 counter
periodically energizes a low power solenoid valve.
As in the other two modes of operation, this allows
actuation gas to stroke the DP-2000 pump. The
rate at which this occurs is a function of operator
input as well as the host computer or other device
that inputs pulses per volume metered. The two
10-position switches on the Z-65 are used to set
the number of pulses the counter will count before
activating the solenoid output. The number of
times the solenoid output is activated is recorded
by the onboard LCD stroke indicator. Sample
volume is again controlled using the DP-2000
volume adjustment knob.
In all three modes of operation, the Z-65 timer/
counter operates using a replaceable internal
battery pack. The battery pack condition is
monitored by way of two indicator LEDs. When
the battery pack needs replacement, the red LED
will illuminate when the solenoid output is
activated. If the battery pack is good, the green
LED will illuminate when the solenoid is activated.
The External Power Option can be used in lieu
of the internal battery pack. The External Power
Option (model # EPO-120) consists of an AC to
DC convertor and intrinsically safe barrier to
convert 120 VAC power to 28 VDC to operate the
controller without the use of the internal battery
pack.
The Solar Power Option would be used in lieu of
the internal battery pack. The Solar Power
Option (model #SPO-12) consists of a 5 watt
solar panel with RM-12 charger regulator module
and internal 12V, 5 Amp hour battery pack.

4.1 The sampler should be a minimum of five
pipe diameters from any device which could cause
aerosols or significant pressure drops.
4.2 The sampler should not be located within the
defined meter tube region (AGA 3 manual).
A = The number of unobstructed, straight pipe
diameters upstream (see AGA - 3 manual).
B = The number of unobstructed, straight pipe
diameters downstream (see AGA - 3 manual).

5.1 DynaPak 2010L
a. The DynaPak 2010L requires a 3/4" FNPT
pipelineconnection.
b. The DynaPak 2010L sampler should be
mounted vertically in a horizontal run of the
pipeline.
c. The end of the sampler probe should penetrate
the center 1/3rd of the pipeline.
d. The end of the sample probe should be cut
parallelto thepipeline.
e. Before applying pipeline pressure to the
DynaPak 2010L, ensure that the isolation valve
and purge valve are closed.
f. After pipeline pressure has been applied to the
sampler, check the probe body/pipeline connection
using a liquid leak detector.
CAUTION:
Incorrect operation of valves (over
tightening) can result in damage to the
valve components (isolation valve
bonnet assembly) which might result in
the valve stem being screwed out of the
probe body. This of course results in
product at pipeline pressure being
vented continually through this port
until this section of the pipeline is shut
in. Be aware of the following
procedures and information.
· DynaPak valves are of soft seat
design and should only be closed
or opened with fingers. No
wrenches should ever be used.
·If a valve will not seal off with
finger tight operation the valve
should have maintenance
performed to allow proper
operation of the valve.

5.2 Optional DPS-2:
a. With the low pressure supply valve and the high
pressure supply valve closed, connect the DPS-2
to the orifice connection tubing.
b. Open the equalization valve.
c. Open the low pressure supply valve or the high
pressure supply valve.
NOTE: Do not open either the low pressure
supply valve or the high pressure supply valve
without ensuring that the equalization valve is
open. Failure to do so may damage the
DPS-2's internal components.
d. Open the other supply valve.
e. Close the equalization valve.
f. Run the free end of the DPS-2 cable through the
cable entry connector located on the upper left
side on the DynaPak 2010L enclosure.
g. Connect the DPS-2 cable as shown in the
diagram.
h. Tighten the cable entry connector, allowing for
enough cable length to open the enclosure.

6.1 Variable pressure/constant volume
cylinders.
Spun cylinders may be installed in a horizontal
position on the DynaPak BackRack vessel rack.
Avoiding traps in the line, install stainless steel
tubing and fittings from the sample discharge port
of the sampler to the product end of the sample
cylinder.
300cc and 500cc spun cylinders may also be
installed in a vertical position. Piping from the
sampler dischage port to the sample vessel
should be arranged so that liquid traps are not
created.
6.2 Variable volume/constant pressure
cylinder.
The free-floating piston cylinder (DuraSite) may be
installed in a horizontal position on an optional
vessel rack. Free-floating piston cylinders should
NOT be installed on the DynaPak BackRack
vessel rack.
Install 1/8" tubing from the sample discharge port
of the manifold to the product end of the vessel.
Avoid traps in this line.
See diagram #9 for DuraSite portable sample
vessel instructions.
6.3 LinkPlus. Install the optional LinkPlus directly
into the sample discharge port of the sampler.
Use stainless steel tubing and fittings to connect
the LinkPlus outlet to the product end of the
sample cylinder.

7.1 When all of the tubing connections have been
completed, close the purge valve on the front of the
sampler probe body. Open the sample probe
supply valve to allow pipeline pressure into the
sampler. Check all connections using a liquid leak
detector.
7.2 Adjust the filter/regulator from the following
ranges:
Pipeline Pressure Actuation Pressure
10 psig (0.69 Bar) to
50 psig (3.5 Bar) Use Full P/L Pressure
Pipeline Pressure
50 psig (3.5 Bar) to

Over 700 psig (48 Bar) to
1500 psig (103.4 Bar) 65 psig (4.5 Bar)
7.3 Turn the stroke adjustment knob on the top of
the pump counterclockwise to set the pump
displacement at .4cc/stroke.
7.4 Move all of the mode switches on the Z-65 to
their off positions.
7.5 Move both timer/counter dials to the 0 position
(00 minutes).
7.6 Move mode switches 1, 2 and 3 to the on
position. The pump will begin stroking once every 2
seconds in a diagnostic test mode.
7.7 Allow the sampler to operate until pipeline
pressure plus is achieved at the sample discharge.
7.8 Return the mode switches to their off positions.
7.9 Check all connections from the sampler dis-
charge to the connection on the sample cylinder
using a liquid leak detector.
7.10 If no leaks are found, the pump and tubing
should be considered tested and functional.
