Gas Analyzer Accessories

In addition to choosing the right analyzer, customers need to be cognizant of other potential issues that could negatively impact measurement performance and reliability.

Sludge and water slugs are part of the normal reality in operating pressurized pipelines. Understand that a sample gas, regardless if it is hot, wet or dirty, often contains contaminants and other unwanted liquid vapors. So, when the ambient temperature inside the pressurized pipeline cools down, the sample gas will condense and, in the process, cause the contaminants and liquid vapors to coalesce into ‘physical sludge’. ‘Pigging’ a dirty gas line (a normal cleaning process carried out by pipeline operators) will also create sludge that could get inside the gas path of an analyzer. Even running hot compressor gases through the pipeline will cause slugs of water to accumulate over time. All these situations can eventually bring about system failure and costly down times due to the analyzer becoming polluted and the sensor becoming damaged. This is why preconditioning a gas sample is one of the most proactive things that customers can do to prevent liquids or contaminants from entering a gas analyzer.

AMI has looked at this issue for many years and, in doing so, developed an effective solution for our customers. We strongly recommend that all customers include our Demister and Liquid Rejection Probe as part of their new installations in place of inadequate, maintenance-intensive coalescing filters or drip pots. Doing so will protect your analyzer and minimize the number of occurrences of unexpected maintenance and downtime.

Customers should also be cognizant if they are working with ambient or negative pressure samples. For these situations, we provide the option of either a fixed pump or portable pump to assist their sample in reaching the sensor. Our fixed pump has CSA approval for Class 1, Div 2, Group C,D areas, while our portable pump is designed to meet Class 1, Div 2, Group C,D applications.

We also offer our Extreme Weather Enclosure for customers, located in regions with severe weather conditions. In places where temperatures could drop as low as -40°F, the Extreme Weather Enclosure will provide added protection and performance. Our Model 210BR, Model 2010BR and Model 3010BR are outfitted with an agency-approved, miniature explosion-proof heater. Requiring only 24 Watts to operate, this low power heater can easily be housed inside our Extreme Weather Enclosure. The enclosure is fully insulated and powdered-coated aluminum. This special configuration will allow you to operate without failure in temperatures as low as -40°F.

Our accessories provide an exceptional layer of protection for your gas analyzers, and they keep your analyzers operating without interruption or having to be taken offline unexpectedly for maintenance. If you are looking for a truly complete solution with minimum maintenance requirements, contact us today and see how AMI innovation can change how you approach gas analysis.
