CDP301

Product catalog summary

Introduction
The CDP301 Condumax Dew-Point Tester is a manual, visual dew-point tester designed for natural gas processing and transmission applications. It utilizes a fundamental cooled-/chilled-mirror dew-point measurement principle and is housed in a lightweight, explosion-proof enclosure.

Key Features

High-definition color LC display for visual identification of water and hydrocarbon dew points.
Automatic mirror cooling rate control compliant with ISO 6327 and ASTM D1142 standards.
Self-contained, rechargeable battery-powered with up to 8 hours of operation.
Exd certified for hazardous areas (IECEx ATEX Zone 1, Class I Division 1/Zone 1, IIB+H2 T3).
Operates at pressures up to 100 barg (1450 psig) with a measurement depression range greater than 60 ˚C (140 °F).
Accuracy of ±0.5 ˚C (±0.9 °F) for mirror surface measurement.

Applications

Natural Gas Processing
Transmission Pipeline Checking
Sour Natural Gas
Validation of online analyzers

Measurement and Operation
The CDP301 features an integral high-definition camera for capturing timestamped images and videos of the mirror surface. The user can observe condensation formation and distinguish between water and hydrocarbon precipitation. The device allows for data storage and transfer via USB.

Technical Specifications

Chilled mirror measuring technique with automated cooling ramp rate.
Depression range up to Δ T >65 °C (149 °F) with an accuracy of ±0.5 °C (±0.9 °F).
Sample flow rate between 0.25 and 0.5 Nl/min.
Pressure measurements in MPa, barg, psig with an accuracy of ±0.25%FS.
Operating pressure up to 100 barg (1450 psig) and sample supply pressure between 20 and 100 barg (290 to 1450 psig).
Rechargeable Li-ion battery with up to 8 hours of life.
High-definition 5.7” full-color display with 5 push buttons for operation.
2GB onboard data storage for logging and image capture.

Accessories and Transport
The CDP301 is fully portable, supplied with a rucksack and wheeled hardcase for easy transport. It includes a purpose-designed sample system for pressure and flow regulation and contaminant removal. The device is compliant for use in hazardous areas and can be mounted on a tripod or bench-top stand.

Conclusion
The CDP301 Dew-Point Tester offers a portable, reliable solution for measuring hydrocarbon and water dew points in natural gas, ensuring compliance with industry standards and facilitating easy transport and operation in various environments.

Process Analyzers Hydrocarbon Dew Point: A Critical Natural Gas Quality Parameter For natural gas producers, pipeline operators, and direct contract buyers, hydrocarbon dew point is difficult to measure and control. It is vital to avoid custody transfer disputes, which can result in shut-ins due to today’s tighter contractual limits. Since 1986, the direct chilled mirror technique incorporated in the Michell Instruments Condumax II is the definitive method of measuring hydrocarbon dew point, and is preferred by most gas producers, pipeline operators, and direct contract buyers around the world....
