Thermal mass flowmeter for the direct mass flow measurement of gas.

The t-mass 65 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 65 is capable of accurate measurement of both low flow rates and leakage, which allows users to optimise plant performances. With its integrated ‘gas engine’, users can select from a list of 20 pure gases such as air, nitrogen, oxygen etc 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 to suit the requirements of the individual application. t-mass 65, 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.
