  • Measuring principle

    Ultrasonic flow

  • Product headline

    Highly robust gas specialist for fluctuating process conditions with compact, easily accessible transmitter.
    Flexible device with user-definable gas mixtures for demanding measuring tasks.
    Accurate measurement of natural and process gas in the chemical as well as oil and gas industries.

  • Sensor features

    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.
    Direct measurement: flow, pressure & temperature. Wetted parts: titanium / 316L. Maximum measuring accuracy: 0.5 %.

  • Transmitter features

    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.
    Compact dual-compartment housing with up to 3 I/Os. Backlit display with touch control and WLAN access. Remote display available.
