Supmea Optical Dissolved Oxygen Monitoring for Aquaculture in Singapore

Project Overview

A commercial aquaculture farm in Singapore needed continuous dissolved oxygen monitoring across multiple culture ponds. Manual sampling could not capture sudden oxygen changes, particularly at night or during changing weather conditions.

The farm introduced an online monitoring system to improve water quality management and support automatic aeration control.

Solution Provided

Supmea supplied DO-7019 optical dissolved oxygen sensors for submerged installation in the ponds. The sensors continuously transmit measurement data to the farm’s PLC and cloud platform through RS485 Modbus RTU communication.

Using optical fluorescence technology, the sensor requires no membrane or electrolyte replacement. Its titanium housing, IP68 protection and automatic temperature compensation support reliable long-term operation in aquaculture water.

Benefits Delivered

  • Continuous dissolved oxygen monitoring
  • Automatic aerator control based on preset thresholds
  • Faster detection of low-oxygen conditions
  • Reduced sensor maintenance requirements
  • Stable integration with PLC and cloud systems
  • Improved support for daily water quality management

Conclusion

The Supmea optical dissolved oxygen monitoring solution helps the farm respond quickly to changing pond conditions, optimize aeration and reduce manual maintenance. It also provides a reliable foundation for expanding digital water quality management across additional ponds.
