Our Goal
Our shared goal is customer satisfaction through operational excellence.
Yokogawa has brought true innovations to industry. We are committed to ensuring accuracy, reliability, and safety of your production system throughout your business life cycle. Our comprehensive solutions and expertise help you achieve more results with less total costs of ownership. Below key technologies shall aim for your operational excellence.
Inductive Conductivity Sensors
The ISC sensors use a high performance engineering plastic of PEEK (polyetheretherketone) that provides abrasion and corrosion resistance.
The sensor has a large bore (17mm) for optimal resistance to fouling processes and when properly installed ,the flow will keep the sensor clean, to help avoid measuring errors. This large bore also allows quick response even on low flow measurement. Also available upon request is a PFA lined sensor that provides excellent heat and chemical resistance.
Dual Frequency Coil Excitation
Magnetic Flow Meters measure flow volume with Faraday's law. The frequency of excitation current given to coils affects in the measurement accuracy and response time. Dual Frequency Coil Excitation is Yokogawa's original technology to ensure ± 0.35 % accurate measurement as well as 0.1 second fast response simultaneously.
Our signal processing technique enables us to bring the benefits of an AC & DC magnetic flow meter into a single magnetic flow meter.
Manual Operation "Hard Manual"
Independent manual override is built into the control circuits, ensuring that control output can continue even when a control circuit including the CPU experiences a problem.
Dust-Proof and Water-Proof Front Panel
The front panel has a dust-proof, water-proof design which is compliant with the IEC529-IP65 and NEMA No.250 TYPE4* standard. This structure provides good protection for the recorder's internal components and the removable storage media drive mechanism.
*Except external icing test.

Some specifications of this product was discontinued.
The AXF magnetic flow meter is a sophisticated product with outstanding reliability and ease of operation, developed on the basis of decades of field experience. Based on FOUNDATION™ Fieldbus specifications, AXF Fieldbus Magnetic Flow meter models offer more flexible instrumentation.
The ADMAG CA magnetic flow meter adopts a system to pick up the electromotive force generated in a fluid by electrodes provided outside a ceramic pipe through the capacitance of the pipe. In addition, the flowmeter employs a prominent high-frequency excitation method that reduces flow noise in low conductivity fluid.
The model ISC40 sensors are designed for use with the FLEXA ISC analyzers. This combination exceeds all expectations for conductivity measurement in terms of reliability, accuracy, rangeability and price performance.
The UT55A and UT52A temperature controllers employ an easy-to-read, 14-segment large color LCD display, along with navigation keys, thus greatly increasing the monitoring and operating capabilities. A ladder sequence function is included as standard. The short depth of the controller helps save instrument panel space. The UT55A/UT52A also support open networks such as Ethernet communication.
