Liquid Analyzer for Turbidity and Chlorine FLXA402T

Providing reliable turbidity and chlorine measurements in Water Treatment Plants since 1959
No.1 Process analyzer supplier to Japanese market*

“Reduce initial cost with reliable products”

“Want to monitor status from remote place”

Many of our customers face these challenges - Yokogawa Turbidity and Chlorine Analyzers resolve them.

The FLXA402T offers multiple connection possibilities, eliminating the need for multiple analyzers and providing greater flexibility. This four-wire analyzer includes a color HMI and an easy touchscreen operation with a simple menu structure in 8 languages for simple and efficient setup and configuration.

With its modular design, the FLXA402T analyzer offers a range of measurement choices with the respective sensor module, including turbidity, chlorine, pH, Conductivity, and 4-20mA input. Dual sensor measurements save your install space and offer additional functionalities, such as pH compensation for the Chlorine analyzer.

Preparing for the Future

Industrial automation is moving toward SMART products, with sensors changing from analog to digital SMART. This transition can affect plant operations and take time to implement fully.

In addition to being a high-performance standalone analyzer, the FLXA402T is also a component of the Yokogawa SENCOM4.0 Platform, SMART sensor systems give you more insight because they possess in-depth knowledge of their health status for predictive asset management and sensor condition to ease troubleshooting.

With the SENCOM4.0 Platform, upgrading to the next generation SMART product is easy and can be done at any time with little impact on operations.

Easy to get information and operate from remote place

Data Mobility

SD card or Ethernet for easy data transfer and remote service, allowing for more in-depth process analysis. 

Application 

  • Turbidity of tap water, sewage, river water and water used in general processes
  • The Chlorine Analyzers intended for measurements in the water distribution network, at pumping stations, water delivery points, schools, and public facilities.

Analyzer specialized for water applications

System Configuration
