The Endress+Hauser super-sensitive t-mass thermal mass flowmeter is the ideal solution for direct mass flow measurement of compressed air, biogas and other utility gas applications.

Proven in a wide range of gas flow applications, the Endress+Hauser super-sensitive t-mass thermal mass flowmeter is the ideal solution for direct mass flow measurement of compressed air, biogas and other utility gas applications. With a turndown of typically 100:1 and a negligible pressure loss, t-mass AT65 is capable of accurate measurement of both low flow rates and leakage, which allows users to optimise plant performances. It can be supplied to suit a wide range of pipe sizes (DN15 to 1500) in circular or square ducting, and is ATEX certified for hazardous area use.

With its integrated 'gas engine', users can select from a list of 20 pure gases such as air, nitrogen, oxygen and you can even customise a specific gas mixture which is ideal for the measurement of biogas.

This allows you to select and programme the pure gas or gas mixture directly on the device, reducing the reliance on factory pre-sets and allowing the user to configure t-mass AT65 to suit the requirements of the individual application.

t-mass AT65, with its online diagnostics, field replaceable sensors, integrated gas tables and Quick Setup operating menu, offers a maintenance-friendly and time-saving direct gas mass flow measurement.

At high temperatures and low pressures, t-mass AT65 is both robust and sensitive, offering you the best of both worlds.
