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.
