Thermal Mass Flowmeters

Thermal mass flow meters for gases provide a direct mass flow or standard volume flow signal without further pressure or temperature compensation. Accuracy and long-term stability make Sensyflow mass flow meters from ABB an excellent choice in gas flow instrumentation.

Applications can be found in compressed air balancing, process industries with gas reactions, or even in biogas measurement at sewage plants. Starting at 8 mm pipe diameter, also applications in chimneys or square ducts can be served. ATEX certifications and PROFIBUS communication allows installation in demanding applications.
