The new Proline t-mass F/I 300/500 thermal mass flowmeters (photo) are reliable and versatile for measuring pure gases and gas mixtures, and each has numerous alarm functions, as well as bidirectional measurement capability and reverse flow detection. The flowmeters are suitable for compressed air, natural gas, protective gas or oxygen. The meter has an all-metal sensor design and unique monitoring functionality. Even when process and ambient conditions significantly fluctuate, t-mass ensures high measurement accuracy (±1.0%) with excellent repeatability (±0.25%). Gas flows with low pressure and a low flow velocity can also be measured easily thanks to a high turndown ratio. t-mass F and I can operate at process temperatures up to 356°F and pressures up to 580 psi. — Endress+Hauser, Greenwood, Ind.
