Reliable oil flow meter supplier for importer

A large-scale thermal power plant, in response to the national Emission Standard of Air Pollutants for Thermal Power Plants (GB 13223-2011), has launched an ultra-low emission retrofit project for its 2×660MW units. The goal is to achieve real-time monitoring and data reporting of pollutants such as SO₂, NOx, and particulate matter. The focus of this project is to upgrade the flue gas flow monitoring unit. The traditional differential pressure instruments were replaced with the SURE Vortex Flow Meter LUGB-A Series to address the measurement challenges in high-dust and wide-temperature-variation conditions, meeting the regulatory requirements of the Ministry of Ecology and Environment for "installation, display, and connectivity".Operating Conditions1.
