Field of application

For a wide range of gas applications Prosonic Flow G provides reliable flow measurement, even with wet gas and changing gas properties and compositions. A pressure-rated sensor housing with rupture disc limits safety risks. The compact transmitter offers high flexibility in terms of operation and system integration: access from one side, remote display and improved connectivity options. Heartbeat Technology ensures compliance and process safety at all times.

  • The measuring principle is unaffected by gas composition

  • Accurate measurement of natural and process gas in the chemical as well as oil and gas industries.

Device properties:

  • Direct measurement: flow, pressure & temperature

  • Wetted parts: titanium / 316L

  • Maximum measuring accuracy: 0.5 %

  • Compact dual-compartment housing with up to 3 I/Os

  • Backlit display with touch control and WLAN access

  • Remote display available

Benefits

  • Flexible device with user-definable gas mixtures for demanding measuring tasks

  • Maximum reliability even with humid or wet gas – sensor design insensitive to condensate

  • High-performance process control – real-time pressure- and temperature-compensated values

  • Efficient solution – multivariable, no pressure loss

  • Full access to process and diagnostic information – numerous, freely combinable I/Os

  • Reduced complexity and variety – freely configurable I/O functionality

  • Integrated verification – Heartbeat Technology
