Endress+Hauser Thermal mass flowmeters

The Proline t-mass F/I 300/500 flowmeters measure pure gases and gas mixtures, including compressed air, natural gas, protective gas or oxygen. They have numerous alarm functions, as well as bidirectional measurement capability and reverse flow detection. Even when process and ambient conditions fluctuate significantly, the flowmeters ensure measurement accuracy to ±1% with repeatability of ±0.25%. A high turndown ration enables gas flows with low pressure and a low flow velocity to be measured. The flowmeters can operate at process temperatures up to 356 °F and pressures up to 580 psi.
