OPTISONIC 3400, Ultrasonic Flow Meter

The OPTISONIC 3400 is a 3-path ultrasonic inline flow meter that’s ideal for a wide range of standard or more demanding municipal water and wastewater applications. For example, it’s great for flow measurement of homogeneous, non-viscous aqueous liquids as well as viscous fluids of up to over 1000 cSt. This ultrasonic flow meter for municipal use, from KROHNE, is also a perfect choice for applications with cryogenic products (as low as -328˚F), media with extended temperature ranges (up to 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.

Using the transit time method, the three parallel acoustic paths of the flow meter allow bi-directional measurement, independent of flow profile, for high accuracy even under less favorable flow profile conditions, for example, short inlet and outlet runs. By means of the velocity of sound, the device is also able to identify process changes or liquid pollution. Its fully welded construction does not cause any pressure loss and is maintenance-free. The OPTISONIC 3400 is available with flange as well as welded connections. It also features enhanced diagnostics and provides various digital communication options.
