The New Optisonic 3400 ultrasonic flowmeter is a three-beam, inline device that can be used for both standard and more demanding applications, in terms of process temperature, pressure and high viscosity. This new multipurpose flowmeter offers bi-directional flow measurement independent of the medium’s conductivity, temperature density and pressure. Based on the transit-time method, the device has three parallel ultrasonic beams that generate a measurement independent of flow profile, with a flow range of 0.3 to 20 m/s and accuracy of ±0.3%. The temperature range extends from –200 to 250°C, and viscosities can reach as high as 1,000 cSt. — Krohne Messtechnik GmbH, Duisburg, Germany
