Liquid Analyzers in the Water Industry

The goal of drinking water treatment is to produce clean, safe, and potable water that meets regulatory standards and is suitable for drinking and other domestic uses.

Industrial water is essential for power generation, refineries, and petrochemical plants. Our measurement and control solutions for water and wastewater seamlessly integrate with main processes.

The goal of waste water treatment is to produce treated water that meets environmental regulations and can be safely released into bodies of water or reused for purposes like irrigation or industrial processes.

All water, regardless of its source, has value. However, with water resources being finite, a focus on "One Water" is necessary to maximize every drop within the water system, ensuring a stable supply of clean and safe water.  As we consider current and future needs, planning and implementation are critical for long-term resilience and reliability, meeting both community and ecosystem demands. Yokogawa believes water is a human right for all. Thus, contributing to a sustainable water cycle is one of our Sustainable Development Goals (SDGs).

• FLEXA™ series analyzers FLXA202
• Continuous on-line industrial measurements
• Most flexible two-wire analyzer available

The FU20 and FU24, all-in-one pH and ORP, sensors show how Yokogawa applies the motto "Simple is best" to sensor technology.

The FLXA402T is the next-generation analyzer for the Turbidity detector and Chlorine sensor. The FLXA402T can connect up to two sensors of Turbidity, Chlorine, pH, and Conductivity, with digital communications availability.

The FLEXA™ series analyzers are modular-designed analyzers used for continuous online measurements in industrial installations. They offer single or multi-sensor measurement.

It is a fluorescent dissolved oxygen sensor that is easy to clean and stable for long term measurement. Sensor replacement is easy on site and reduces maintenance costs. It is possible to measure oxygen in a wide range including low concentration measurement.
Suitable for use in water treatment plants such as sewage treatment plants and wastewater treatment plants under severe measurement conditions.
Can be used in combination with FLXA402 liquid analyzer by digital communication.

Intended for the low conductivity applications found in the semi-conductor, power, water and pharmaceutical industries, these sensors are in a convenient compact style.
