Process liquid measurement the smart way

The OPTISONIC 3400 is great for process liquid measurements of conductive and non-conductive, low and high viscous liquids, from -200 °C to +250 °C / -328...+482 °F medium temperature. The liquids can be applied without too much consideration of chemical inertness, turndown ratio, accuracy span, maintenance or other risks related to wear or necessary replacements.

Unlike traditional mechanical flowmeters, the OPTISONIC 3400 ultrasonic flowmeter can measure multiple products without jeopardising accuracy or need to recalibrate.

Identification of the product through velocity of sound

The liquids should be single-phase and relatively clean. Because of the differential transit time principle, pollution levels in the liquid should not exceed a few percent of gas bubbles and/or solid particles.

Bi-directional by nature

With known and stable liquid density, in addition to volumetric flow, mass measurement is also possible. Bi-directional flow measure­ment is a standard feature of the OPTISONIC 3400 which can also be used as a smart safety feature, e.g. triggering an alarm in case of a reverse flow.

This makes the OPTISONIC 3400 a truly unique multi-purpose, all-round ultrasonic flowmeter.
