PRODUCT DETAILS
This compact thermal mass flow meter measures the mass flow rate and provides a direct output of standardized volume flow rate without requiring additional pressure or temperature measurement. Thanks to the integrated thermal mass flow principle, compensation is automatic and highly accurate.
The device is specifically designed for installation in confined spaces. An integrated flow straightener eliminates the need for inlet and outlet sections, allowing flexible installation even in challenging pipe layouts.
The sensor can be easily installed and removed, while the integrated measuring section remains in the pipeline during cleaning or recalibration and can be securely closed using a sealing cap. With no moving parts, the instrument offers low maintenance requirements and long-term reliability.
It is suitable for compressed air and non-corrosive gases such as nitrogen, oxygen, argon, and helium.
