PRODUCT OVERVIEW
FLXA21-D-P
The YOKOGAWA FLXA21 is a modular two-wire liquid analyzer designed for continuous online measurement in industrial installations. Its architecture combines a housing assembly with one or two sensor modules, allowing the analyzer configuration to be matched to the required measurement technology.
Depending on the installed sensor module, the FLXA21 platform supports pH/ORP, contacting conductivity, inductive conductivity, and dissolved oxygen measurement. Two compatible sensor modules can be installed for selected same-type combinations, including pH/ORP + pH/ORP, SC + SC, and DO + DO.
The FLXA21 uses a 2-wire 24 VDC loop-powered architecture and can communicate through HART, with FOUNDATION Fieldbus and PROFIBUS PA available in applicable configurations.

WHERE THE FLXA21 PLATFORM FITS
PROCESS WATER
Suitable measurement configurations can support water-quality monitoring where continuous pH, conductivity, resistivity or dissolved-oxygen measurement is required.
CHEMICAL PROCESS
The modular sensor architecture allows the analyzer platform to be configured around the measurement technology required by the process.
UTILITY & TREATMENT
Loop-powered operation and industrial enclosure protection make the FLXA21 suitable for distributed online analyzer installations.
FLXA21 FAMILY CONFIGURATION VIEW
The FLXA21 family is built around a common two-wire analyzer platform. Model configuration is determined through power, housing, display, sensor-input and communication suffixes.
FLXA21-D-P
2-wire analyzer platform with -D power designation and plastic housing designation.
Sensor Modules
pH/ORP, contacting conductivity, inductive conductivity and dissolved oxygen modules are available according to configuration.
Communication
HART is supported, while FOUNDATION Fieldbus and PROFIBUS PA are available for applicable variants.
Application Choice
Selection should be matched to sensor technology, hazardous-area requirements and communication architecture.
PURCHASING CHECKPOINT FOR FLXA21-D-P
Before replacement or system integration, confirm the installed sensor module, communication requirement, display configuration, hazardous-area classification, power-loop arrangement and sensor wiring. The FLXA21 suffix structure determines important configuration details, so the complete existing model code should be matched before ordering.

FLXA21-D-P FAQ
01 · Can FLXA21-D-P replace another FLXA21 unit directly?
A direct replacement should not be assumed from the FLXA21 family name alone. The sensor module, communication type, area classification, display configuration and complete suffix code should be matched with the existing installation before replacement.
02 · Does FLXA21-D-P support two measurement points?
The FLXA21 platform can use one or two sensor modules. Two-module operation is available for defined same-type combinations such as pH/ORP + pH/ORP, SC + SC and DO + DO. The actual replacement configuration must match the installed module arrangement.
03 · Is FLXA21-D-P suitable for a loop-powered replacement project?
The FLXA21 platform uses a 2-wire 24 VDC loop-powered architecture. For an existing installation, verify the loop supply, signal wiring and communication arrangement before replacing the analyzer.
04 · Which sensor technologies can FLXA21-D-P be configured around?
The FLXA21 platform supports pH/ORP, contacting conductivity, inductive conductivity and dissolved oxygen measurement through the corresponding sensor-module configuration. The installed module determines the available measurement function.
05 · What should be checked when ordering FLXA21-D-P for an existing system?
Check the complete model code, installed sensor module, communication method, hazardous-area requirements, power arrangement, display configuration and sensor wiring. These details determine whether the replacement matches the existing process loop and measurement architecture.
