ATF2000 Series

ALIAMASS Thermal Mass Flowmeter
Model ATF2000 Series

ATF2000 Series thermal mass flowmeter is designed on the basis of thermal dispersion.
It adopts method of constant differential temperature to measuring gas flow.
It has the advantages of small size, high digitization, easy installation and high accuracy.
ATF2000 is a multi-functional thermal mass flow meter that measures mass flow and volume flow.
With insertion type connection, the meter can achieve a hot-tapped installation and maintenance.
