Detail GAS VELOCITY MONITOR VCEM5100
Codel International has announced that the VCEM 5100 flow monitor has received certification under QAL 1 of EN 15267 requirements. Tested by TUV Rheinland at a power station operating under the Waste Incineration Directive, the VCEM 5100 is certified for use on all EU regulated stationary emissions. The VCEM 5100 represents the latest generation of Codel’ s in-situ flow monitors. Advantages of the technology it offers include: * Accurate operation in stacks with hot, dusty and aggressive gases. * It does not require stable, laminar flow conditions in the stack. * As the sensing elements are isolated from the stack gas by an air curtain they are unaffected by temperature constraints. * Maintenance requirements are low and easily performed. * Operation at significantly higher temperatures than other continuous monitoring technologies. * An optional off-line checking system for the AST linearity test. The VCEM 5100 is a standalone unit that can be easily integrated into an existing or proposed CEMS system. It uses a unique measurement method, whereby naturally occurring infrared patterns emitted from moving flow disturbances are measured by two passive infrared sensors a fixed distance apart. Stack gas velocity is calculated by measuring the time of flight of these transient events between the two sensors. A cross-correlation algorithm establishes the uncertainty of the measurement and excludes invalid data. With the coming EU requirements for monitoring mass flow in stacks, the VCEM 5100 offers a cost effective flow monitor with high accuracy and low maintenance requirements.
