  • Measuring principle

    Electromagnetic

  • Product headline

    The flowmeter with a weight‐optimized sensor and a modular electronic concept. Fully suitable for standard applications in the water and wastewater industry.

  • Sensor features

    Reduced installation costs – flexible mounting by one‐of‐a‐kind lap‐joint flange concept (DN <350/14"). Energy‐saving flow measurement – no pressure loss due to cross‐section constriction. Maintenance‐free – no moving parts. Up to 30 % less sensor weight. Nominal diameter: DN 25 to 2400 (1 to 90").

  • Transmitter features

    Fast commissioning – application‐specific Quick Setups. Safe operation – display provides easy readable process information. Fully industry compliant – IEC/EN/NAMUR. 2‐line backlit display with push buttons. Device in compact or remote Version.
