Overview

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.
