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.

Dual Frequency Coil Excitation

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.

Manual Operation

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.

Dust-Proof and Water-Proof Front Panel
