Michell Instruments 1
INTRODUCTION
1 INTRODUCTION
The CDP301 provides battery-powered manual visual measurement of the hydrocarbon
dew point and water dew point of processed natural gas. It is the result of more than
30 years’ experience in the supply of Dew-Point Testers to the worldwide oil, gas and
petrochemical industry.
The system consists of a hydrocarbon and water dew-point sensor cell and control
electronics housed in an Exd enclosure. A sample gas handling system to prepare the
gas sample prior to entry into the CDP301 Dew-Point Tester can also be supplied. The
Dew-Point Tester is designed to be positioned close to the process sample test point. It
is ATEX and IECEx approved and is also approved for use in North America in accordance
with the requirements for the USA and Canada. These and additional International
approvals are listed in the Certication section of this manual. Certicates are available
on the Michell Instruments website. A marking label located on the analyzer will identify
appropriate approvals.
The enhanced cooled-mirror principle of the CDP301 allows easy detection of
hydrocarbon or water dew point with the ability to review what has been observed
later. Key components of the dew-point tester are measurement cell, metallised-ceramic
mirror with integrated PT1000 resistance thermometer, triple-stage TEC (thermo-electric
cooler), hi-resolution colour camera, colour LCD display, tactile button HMI, operation
and measurement electronics, and rechargeable battery pack.
Standard accessories include a wheeled transport/storage case (suitable for non-
hazardous/safe area locations only) and backpack (of anti-static material) to carry the
CDP301 and sampling system to the location of use. A universal AC supplied battery
charger is provided (which must only be operated in safe area location). Spare battery,
sampling system and sample hoses are also available as optional accessories.
1.1 Sample Gas Path
The CDP301 measurement system must be supplied with gas at the required pressure
and ow via a sample gas handling panel. Sample gas entry and exit ports pass the
gas through ame arrestors. The inlet connection has a ow restriction device
tted. This is a mandatory safety device that limits pressure rise within the
Exd enclosure in the event of a gas leak occurring. The ow restriction device
must not be removed.
The Dew-Point Tester system components are housed within a cast, copper free aluminium
EExd rated enclosure. The enclosure has a screw cover incorporating a sealed window.
It is chromate primed, polyester coated in black, and provides environmental ingress
protection to IP64/NEMA4X. An enclosure breather is tted in the form of an additional
ame arrestor. It is important that no pipe connection is made to this breather and that
no restriction is allowed to occur.
All sample wetted metallic parts are manufactured in AISI 316L stainless steel with
Viton soft parts that comply with the NACE standard MR-0175 (latest edition). Tube
ttings are twin ferrule Swagelok© compression type.

INTRODUCTION
1.2 Operating Overview
The CDP301 is a manual visual instrument. It is designed to follow the requirements
as described in ASTM D1142 and ISO6327. Using a simple button push, the measured
hydrocarbon and water dew-point temperature, pressure, date and time are stored and
indexed for review and retrieval/download at a later date.
1.3 User Display and Interface
The CDP301 Display and User Interface (UI) is presented via the circular window of the
enclosure. The unit is operated using 5 buttons, which allows full control of the UI. The
cover is fully detachable for greater access into the enclosure for service. During normal
operation of the instrument the cover must remain fully secured.
1.4 Calibration
Prior to shipment, the cooled-mirror dew-point sensor within the instrument undergoes
stringent factory calibration using high purity hydrocarbon gas of known dew point.
Due to the inherent stability of the instruments, only periodic calibration maintenance
is required under normal operating conditions. (See Maintenance Section below.)
1.5 Storage Instructions
The CDP301 has been designed for the accurate manual visual detection of hydrocarbon
and water dew point within natural gas. In order for the Dew-Point Tester to be functional
upon use it should be stored in accordance with the guidelines below:
• The Dew-Point Tester must be housed in a sheltered area, out of direct
sunlight and rain.
• The Dew-Point Tester should be stored to minimize the possibility of
sitting in ground water.
• The temperature within the storage environment should be maintained
between 0 and +50°C (+32 and +122°F).
• The humidity within the storage environment must be non-condensing.
• The storage environment must not expose the Dew-Point Tester to any
corrosive elements.
• The Dew-Point Tester may stay assembled with its sample conditioning
system (if supplied).
• All process connections should remain disconnected.
• All protective coatings should remain in place until use.
For the period from rst use of the CDP301, the following precautions should be followed:

INSTALLATION
2.4 Gas Sample Connections
The following points should be considered when installing the sample gas supply line:
• PTFE tape is recommended for pipe connections.
• Solvent-based pipe thread sealant should not be used, as condensable
components or contaminates can be leached during the curing period.
Care and attention to the position and installation of the tubing will minimize problems
caused by avoidable contamination. The most common issue with sample ow is the
accumulation of liquid in impulse lines during a shutdown period. If the measurement
system has not been isolated, condensate can be displaced, on re-start, into components
and associated tube work. An optional CDP301 sample system is available from Michell
Instruments:
Figure 2 Michell Sample System
2.4.1 Connecting the Michell Sample System (optional accessory)
DO NOT permit pressures greater than the specied safe working pressure of
100 barg (1450 psig) to be applied directly to the instrument.
Ensure the instrument is properly secured before use, i.e. tripod mounted or
tted to a suitable benchtop mounting.
1. Ensure the isolation valve to the sample tapping point is fully closed.
2. Connect the Michell sample system to the CDP301 inlet and outlet
connections and tighten the ttings.
3. Ensure pressure regulator PR1 is fully closed.
4. Connect the sample tapping point to the sample system using suitable
stainless steel tubing or high-pressure rated hose (such as Swagelok B
series).
5. Connect the vent line (if available) to the owmeter’s 1/4” FNPT outlet
connection and ensure the isolation valve (if tted) is fully open.
6. Refer to Section 4, SYSTEM START-UP AND MEASUREMENT PROCEDURE,
for tester operation.

CDP301 Dew-Point Tester User’s Manual
Michell Instruments 9
INSTALLATION
For proper sample system operation, Michell Instruments' recommendations are:
• The sampling point from the process line should be taken from the top
of the process line. If a radial probe is used, the orice should face
downstream.
• It is recommended that Viton is used for all O-rings.
• The internal volume of the impulse tubing connecting between the process
line and this product should be as small as possible to minimize response
lag time to changing process conditions.
• Piping should be lagged and/or trace heated if ambient temperatures
could cause the sample gas to fall below its dew-point temperature.
• A drain valve should be placed at the lowest point in the system.
• It should be standard procedure to isolate this product during shutdowns
or when plant problems are being experienced and to adequately purge
the supply lines before restarting.
• The relatively large area of surfaces and internal volume of inline
components can be particularly troublesome if contamination is
experienced. Prolonged purging, or stripping and cleaning, followed by
re-purging with gas may be necessary to remove the contamination.
• Avoid sample gas streams that are already very close to the dew point or
which have dispersed liquid within them. In such cases, sampling from
fast loops and/or from downstream of existing catch pot/coalesce systems
is always preferred.
Failure to observe these recommendations will potentially cause problems of
contamination as well as causing consequential inaccurate, unreliable and inconsistent
measurement results. If a top-entry sample point is not available, extra attention should
be given to the design of the sample line installation to avoid unwanted contamination.
2.4.2 Considerations when setting sample pressure and flow
In-line particulate ltration is recommended to avoid contamination of the mirror surface
and generally within the dew-point tester. A 15 micron (or smaller) sintered stainless
steel lter is suitable.
Pressure within the dew-point sensor cell is indicated on the display of the CDP301.
Be aware that the ow restrictor tted to the gas inlet connection will cause a small
pressure drop between supply pressure and analysis pressure within the dew-point
sensor cell. Process pressures less than 20 barg (290 psig) cannot be sampled.
Set the sample ow rate to 0.5 Nl/min (0.03 Nm3/hr)
The sample gas outlet should be vented to atmosphere (where permitted and in
accordance with safety procedures at the location of use) or exhausted into a low-
pressure are system (<3 barg/43.5 psig back-pressure).
