FLOWSIC100 Flow measuring device

FLOWSIC100 – Volume flow measuring devices for continuous emission monitorin

The FLOWSIC100 series provides solutions for a wide variety of measuring tasks – from calculating volume flows in process analysis and environmental monitoring applications. Thanks to its modular design, the FLOWSIC100 series can be used in many applications.

Emissions monitoring Continuous, non-contact, and direct – the FLOWSIC100 devices supply accurate and reliable measurements of the volume flow and gas velocity in flue-gas, exhaust-gas ducts or chimneys. They fulfill the requirements of the German Clean Air Regulations and the Federal German Pollution Control Act (13th, 17th and 27th Impl. Ordinances), and are conform with U.S. EPA specifications.

Process measurement The reliability, precision, and short response times of the FLOWSIC100 series significantly enhance the efficiency of open and closed-loop control circuits. The instantaneous flow measurement reflect the current process status – even under difficult conditions, such as high temperatures or pressures.
