SSI | SSII | SSIII | SSIV | Combined Systems | Natural Gas

Model SSI - Low Pressure Sample System Sample inlet pressure up to 28 barg Sensor operating at atmospheric pressure Process and auxiliary sample inlets with manual selection valve Outlet connection for sample recovery or disposal Particulate filtration, 99.99% to 0.6 microns Sample pressure control and indication Sample flow control and indication, 0-5 l/min Sample flow schematic and component labelling on front panel Panel or surface mounting with optional weatherproof enclosure Can be situated in a hazardous environment Low Pressure Sample System - Maximum inlet pressure up to 28 barg, with sensor operating at atmospheric pressure. This system is designed for gas or general compressed air sampling for maximum inlet pressure of 28 barg, with the moisture sensor operating at atmospheric pressure. The system provides for all necessary pressure and flow control and includes sample filtration to protect against particulate contamination. Auxiliary inlet connection is provided for a second sample stream or for injection of a calibration gas. An outlet connection is also included to allow sample recovery or disposal.

Natural Gas Sampling Systems CENELEC certified sensor for use in hazardous areas* Tough moisture sensor technology that is responsive to water vapour only Constructed using high quality components to the highest standards of workmanship All systems have IP66 rated Stainless Steel weatherproof enclosures as standard All metal wetted parts are 316 Stainless Steel (NACE Compatible) Filtration, pressure control and sample conditioning selected to suit specific application High inlet pressures up to 240 barg Sample and by-pass loop flows returned to process or disposed of through High Pressure or Low Pressure flare systems Alpha Moisture Systems have considerable experience of moisture analysis in Natural Gas applications both on and off shore. A number of standard sample systems are available for common applications and our design engineers are able to provide custom made solutions to the more complex applications. Through close co-operation with customers during design, assembly and commissioning you can be assured that our Natural Gas sample systems will meet the most demanding standards for performance and reliability. Common factors in many Natural Gas applications are extreme environmental conditions, high levels of contamination and high process pressures often with the process stream in liquid phase. In view of this, our Natural Gas systems have the following general features:
