Endress+Hauser new generation Proline t-mass F/I 300/500 –offer bidrectional measurement and reverse flow detection.
Proline t-mass 300/500 measuring system comes with a gas engine as standard offering 22 gases to choose from and corresponding gas mixtures with up to eight components. Proline 300/500 units comprise an in-line version for pipes DN 15 to 100 and an insertion version for pipes and ducts DN 80 to 1500. Both provide dynamic correction for changes in pressure, temperature and gas composition.
The flowmeters offer measuring accuracy (±1.0 per cent), repeatability (±0.25 per cent) and turndown (up to 1000:1), and temperature measurement up to 180°C, and pressures up to 40 bar. It offers SIL compliance and high operational safety, with heartbeat technology for diagnostics, monitoring and device verification.
Various transmitters are available: Proline 300 (compact) or Proline 500 (remote) series, with up to four inputs and outputs.
