  • Measuring principle

    Coriolis

  • Product headline

    Robust high-pressure flowmeter with a compact, easily accessible transmitter.
    For premium accuracy at highest process pressures, fully suitable for offshore conditions.

  • Sensor features

    Maximum safety – highest resistance to stress corrosion cracking. Fewer process measuring points – multivariable measurement (flow, density, temperature). Space‐saving installation – no in-/outlet run needs.
    Measuring tube in 25Cr Duplex, 1.4410 (UNS S32750). Process pressure up to PN 250 (Class 1500). Nominal diameter: DN 80 to 150 (3 to 6").

  • Transmitter features

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