The SENCOM SMART Sensor System

4-wire SMART Sensor Platform for Turbidity/Chlorine FLXA402T

Changing technologies don't have to result in negative consequences putting throughput, quality, or compliance at risk. The advanced flexibility function features multi-input, allowing the connection of up to 2 sensors at one unit.

The FLXA402T can handle new SMART sensors (Turbidity detector/Chlorine detector) and conventional pH/Conductivity sensors. SENCOM4.0 Platform allowing an easy upgrade to digital SMART sensors in the future, giving you more flexibility and optimizing your OPEX.

Turbidity Measurement

The biggest problem with the turbidity meter is the dirt on the sensor. Easy to clean cell structure, Automatic wash system, Long life time light source contribute to the reduction of maintenance costs.

Chlorine Measurement

Environmentally friendly with the right amount of chlorine injection, minimizes remote maintenance and reduce maintenance time.


pH and Conductivity Measurement

Yokogawa’s pH and Conductivity sensors are highly reliable and very unique. You can select the most valuable sensor.

pH and Conductivity sensors

Analyzer specialized for Tap water treatment process

Tap Water treatment process

Water Treatment Application

1. Sedimentation
Receiving well 
Raw water contains sand, pebbles and soil. They are removed by sedimentation in the middle of a gentle stream.
-Monitor Turbidity, pH and SC

2. Stabilization
Receiving well
The well adjust to keep the water level constant and pressure for the next process.
-Monitor Turbidity, pH and Chlorine

3. Flocculation
Flocculation basin

The raw water with the coagulant is slowly agitated ."Floc" is a group of fine sand and soil  and  gathered together by the action of a coagulant. By creating flocs, particles such as sand and soil become relatively large and easily sink.
-Monitor Turbidity and pH

Flocculation basin

4. Sedimentation
Sedimentation basin
Flocs are sunk in a quiet stream, removing sand and soil ( flocs) from the water
-Monitor Turbidity, pH

5. Sand filtration
Sand filtering
A layer of sand or gravel filters the water and removes fine particles
-Monitor Free chlorine, Turbidity

6. Chlorination
Mixing basin
Added chlorine for disinfection
-Monitor Free chlorine, Turbidity and pH

7. Clean water reservoir
Water reservoir

Store clean water in the distribution reservoir and adjust the water amount for distribution
-Monitor Turbidity , Free chlorine and pH

Water reservoir

8. Distribution pump
Send the water from the distribution reservoir to the water supply station. Water is sent to each distribution station / reservoir using water pipes and supplied to each household or facility.
-Monitor Turbidity, Free chlorine and pH

9. Distribution Tank and Piping
Distribution reservoir
Keep enough water for use
-Monitor Turbidity, Free chlorine and pH

Air purging is required for electrode unit and liquid pump by air pump or compressor air (industrial air). It is required to protect electrode from chlorine gasses which will affect the metal parts.
The FC800D and the RC800D are not suitable for outdoor installation. Strongly recommend installing inside because of pump structure. If you want to install outside, a separate rainproof cover is required and take care install place environment (no co...
Within ordered range, you can set the FLXA402T analog output range seamlessly. Cannot change ordered analyzer measurement range.
Beads become gradually smaller because of friction, and decreases cleaning efficiency. So, we recommend replacing beads once a year.
Rotation electrode will get damaged in case there is no water in the measurement cell. To avoid this situation, the FC800D and the RC800D measurement electrode rotation is automatically stopped. This function makes rotation electrode lifetime longer ...
