Hydrocarbon dewpoint monitor

June 2005 Analytical Instrumentation & Environmental Monitoring

Ametek's Model 241CE dewpoint monitor is a quality control tool for natural gas processing, distribution and consumption. Detection and measurement of hydrocarbon dewpoint is achieved in a single cell, single cycle operation.

The instrument is sensitive enough to detect trace amounts of dew, yet strong enough to withstand saturation levels and process fluctuations such as temperature, pressure and flow rate. A proprietary multiple stage filter protects the analyser from most likely sources of contamination such as aerosols, particulates and liquid slugs. The programmable alarm system will automatically activate when problems are detected.

A dewpoint monitor on a pipeline ensures accurate and continuous monitoring, even at remote or hazardous locations. The Model 241CE is the economic solution to detecting costly problems such as off-spec gas, plugged lines and compressor station malfunctions.

The monitor uses chilled-mirror technology, and all monitoring and measuring of dewpoint is done automatically under control of an onboard computer, rather than by an operator. Designed for unattended operation, the monitor carries CSA (Class 1 Div 1, Group C & D) and Cenelec (Zone 1) certification for use in hazardous areas. It may be located local to a plant or in remote locations. It requires only electrical power and a supply of dry purge gas, therefore fast and accurate readings are obtained with little service and maintenance.
