MCERTS Success for In-Situ Flow Monitor

CODEL International (UK) is pleased to announce that the VCEM 5100 flow monitor has successfully received MCERTS certification. Tested by TUV Rheinland at a power station operating under the Waste Incineration Directive, the VCEM 5100 is certified to QAL 1 of EN 15267 requirements for use on all EU regulated stationary emissions.

The VCEM 5100 represents the latest generation of CODEL’s world renowned in-situ flow monitors The VCEM 5100 technology offers significant benefits over other types of flow measurement devices: it operates accurately 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, aintenance requirements are very low and easy to carry out, it can operate at significantly higher temperatures than other continuous monitoring technologies, and there is an optional off- line checking system for the AST Linearity test.

The VCEM 5100 is a standalone unit which can be easily integrated into an existing or proposed CEMS system. It  uses a unique measurement method, whereby naturally occurring infra-red patterns emitted from moving flow disturbances are measured by two passive infra-red 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 EU requirements for monitoring mass flow in stacks in mind, the VCEM 5100 represents a cost effective flow monitor with superb accuracy and very low levels of maintenance required.
