CEM - Abstract

Abstract Information :

Based on the technology, modern ultrasonic flow meters offer significant advantages for actual and future demanding continuous emission monitoring:

- cross-duct integral measuring method,
- measurement results independent of gas conditions (density, moisture etc.),
- extended and easy-to-use diagnostic capabilities,
- high flow turndown, no pressure loss.

The ultrasonic sensor is the heart of a reliable measurement. Therefore optimum adaptation of the sensor for a specific application is important for best meter performance. The presentation describes innovative sensor solutions focused on challenging application conditions as seen in wet and very hot gases for example.

Ensuring high reliability of measurement is as important as accurate measurement can still be achieved, even with non-ideal installation conditions. Single probe solutions provide minimal installation effort even in limited space. Multipath meter configurations can be solutions for better compensation of profile disturbances.

Modern emission measurement and control also means early detection of required maintenance or repair at an early stage, before the measurement is lost. The presentation will provide an overview of actual diagnostic capabilities of ultrasonic technology and CEM systems (integrity check).

Finally, individual device solutions for selected installations will be presented. These emphasize the advantages of the latest ultrasonic technology for CEM flow measurement.
