Liquid Analyzer for Turbidity and Chlorine FLXA402T
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.

FLXA402T Features
Support up to 2 sensors
FLXA402T has a modular structure and can insert up to 2 sensor
modules. You can choose the Turbidity module or Chlorine module as
a 1st module, and Turbidity module, Chlorine module, pH module, or
conductivity module is available as a 2nd module.

Expert Guide: Clear Touch Panel Display for Improved Operability
The FLEXA™ series analyzer provides improved operability with
intuitive touchscreen operation, featuring a clear display and
user-friendly indication with eight languages. Sensor status and
estimated maintenance time notification improve efficiency. The
interactive screen is housed in a robust aluminum die-cast housing.

Advanced Flexibility: Modular Design for Increased Scalability
The FLEXA™ series analyzer features a modular design with
replaceable sensor modules, enabling the construction of various
systems. FLXA402T allows for the connection of up to two possible
sensors resulting in a reduction in CAPEX and OPEX.
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 trouble.
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.

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.

System Configuration
Turbidity and Chlorine 2 in 1 system configuration
The first module can be connected the Chlorine sensor unit or the
Turbidity detector unit, and the second module can be connected the
Chlorine sensor unit, Turbidity detector unit, pH sensor or
conductivity sensor. For example, Chlorine sensor unit and
Turbidity detector unit can be controlled by one Liquid Analyzer.
