Ключевые технические преимущества
-
Wet Gas Robust Design: Unlike standard ultrasonic meters that may fail when liquids are present, the DRU-S features a “wet gas robust” architecture. It utilizes high-performance titanium sensors that are resistant to the corrosive and erosive effects of produced water and hydrocarbons, ensuring continuous operation in non-dehydrated gas streams.
-
Liquid Indication Diagnostic: A standout feature of the DRU-S is its unique ability to detect the presence of liquids in the gas stream. This diagnostic capability provides operators with real-time insight into process upsets or changes in well behavior, allowing for better management of separators and dehydration units.
-
Extreme Turndown (≥ 100:1): In gas production, flow rates can fluctuate wildly as a well ages or during different production cycles. The DRU-S covers a range that would typically require changing multiple orifice plates, reducing manual labor and the risk of measurement gaps.
-
Zero Pressure Drop: The full-bore design ensures that there is no restriction to the gas flow. This is critical for low-pressure wells where every millibar of pressure counts toward maintaining production and preventing the well from loading up with liquids.
-
Atmospheric Pressure Operation: While many high-pressure ultrasonic meters struggle at low pressures, the DRU-S is capable of measuring from atmospheric pressure up to the full rating of the pipeline, providing flexibility across the entire lifecycle of a gas well.
-
Remote Monitoring & Plug & Play: The device connects seamlessly to the SICK Monitoring Box. This enables remote diagnostics and condition-based maintenance, allowing engineers to verify meter health from the office and eliminate unnecessary site visits to remote well pads.
