innovative Construction Maximum durability for critical processes The sensor OPTISONIC 3000 features a robust, fully welded construction with patented inert metal transducer technology. The mechanical construction of tubes, process connections and transducers are standardised for all versions, including meters for demanding applications such as high viscosity, extended process temperatures and cryogenic process temperatures. The sensor is backward compatible with earlier models. With the full bore unobstructed sensor tube without moving parts, the flowmeter measures bi-directionally,...

superior Performance The signal converter of OPTISONIC 3400 is a truly advanced solution with multiple choices I/Os, and communication protocols, including HART® 7, FOUNDATIONTM fieldbus, Modbus, and PROFIBUS® PA. All communication protocols include diagnostics compliant with the NAMUR NE 107 guideline. This is an operator-friendly signal converter which quickly and accurately alerts process operators to less than ideal process conditions. Being able to react in a timely fashion, based on good information, ensures that consistent process and product integrity can be maintained. Of course,...

ultimate Efficiency Process liquid measurement the smart way The OPTISONIC 3400 is great for process liquid measurements just about anywhere, as long as the liquid is 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. In return all conductive and non-conductive 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...

ultimate Efficiency 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.

easy Handling Trouble-free installation The installation requirements for the entire range of OPTISONIC 3400 flowmeters were specifically optimised for ease of use and time saving efficiency. Commissioning the flanged flow sensor is easy, without the need for auxiliary parts like grounding rings, earth cables, flow straighteners or supports to bear the weight. What has to be be considered to achieve optimum performance is the minimum required inlet/ outlet sections of 5DN/3DN. Designed for easy handling, the flow sensor is lightweight, with compact dimensions. Mounting the flow sensor in...

easy Handling Superior ease of use Commissioning the new UFC 400 signal converter is consistent with the easy installation approach of the OPTISONIC 3400. The flowmeter is factory programmed according to customer requirements. The electrical connections of the signal converter are straightforward and all I/O connections (basic I/O, Ex-i I/O, modular I/O) are similar to all other KROHNE GDC devices. One new enhancement is the user display which is equipped with both optical and push buttons. For the choice of fieldbuses, the accompanying DTMs, DDs and drivers are available free of charge via...
