OPTISONIC 3400

Ultrasonic flowmeter for liquid process applications

  • Accurate 3-path meter: large dynamic range, maintenance-free, no pressure loss
  • Cryogenic (-200°C/-328°F) and extended temperature (+250°C/+482°F) versions; viscosities up to over 1000 cSt
  • Flange: DN25…3000 / 1…120″, max. PN200 / ASME Cl 1500; also weld-ends
  • 3 x 4…20 mA, HART®, Modbus, FF, Profibus-PA/DP

The OPTISONIC 3400 is a 3-path ultrasonic inline flowmeter designed for a wide range of standard or more demanding process applications with homogeneous, non-viscous aqueous liquids as well as viscous fluids of up to over 1000 cSt. It is also the perfect choice for applications with cryogenic products (as low as -200°C / -328°F), media with extended temperature ranges (up to +250°C / +482°F) as well as low or extreme pressure ratings. The OPTISONIC 3400 offers a broad range of diameters – from DN25 / 1″ for dosing purposes to DN3000 / 120″ for water transportation pipelines.
