MPC-Buoy
The patented MPC-buoy combines online water quality monitoring, telemetring and ultrasound technology to provide the state-of-the-art treatment against algae and cyanobacteria in ponds, lakes and dams. by making use of efficient solar panels, the MPC-Buoy will work autonomous, 24/7 worldwide.

Interactive Algae & Cyanobacteria control

1: Monitor water quality

MPC-Buoy provides a complete overview of the water quality by collecting the following parameters:
  • Chlorophyll α (green algae)
  • Phycocyanin (blue-green algae)
  • pH
  • TSS
  • Dissolved oxygen
  • Temperature
2: Predict algae blooms

Collected data is delivered real-time through radio, 3G or GPRS telemetry. MPC-View is a web based software, that provides a clear overview of your water quality and other technical parameters. Based on these data, a bloom can be predicted a few days ahead.

3: Control algae

With help of the MPC-View software, the most optimal ultrasonic program can be determined based on the present type of algae or cyanobacteria. If the MPC-View predicts a bloom, the LG Sonic’s will be set to a different program. This way, LG Sonic controls algae interactively without risking algae to become resistant to ultrasound with a range of 500m (1650 ft) diameter

LG Sonic e-Line 


Most advanced ultrasonic algae and biofilm control


  • Uses different ultrasonic programs for more efficient algae control
  • Integrated wiper for minimal maintenance
  • Controlled and monitored remotely with GSM module
  • Connect multiple transmitters for better coverage of a water surface or different sites.




Different ultrasonic programs for more efficient algae control

The new LG Sonic e-Line incorporates the unique Chameleon TechnologyTM.  This technology enables you to change the frequency program, depending on your application or the micro-organism you want to control. By selecting the most effective frequency range, the LG Sonic e-Line can actively target algae and biofilm in any water body. All frequency programs have been scientifically proven to be effective for its corresponding algal group.




Multiple transmitters
The LG Sonic e-Line offers the possibility to install up to 4 transmitters on one single electronic control box. Every transmitter can be programmed via the same e-box and can work on separate programs depending on the water parameters and degree of treatment desired.This option allows easier installation and treatment in situations where several reservoirs need to be treated or the water body has a bend or curve.


Automatic cleaning of the transmitter head with the integrated Wiper
The LG Sonic e-Line is the first and only ultrasonic system world-wide that has an automatic cleaning system that wipes the transmitter head.This ensures 100% effective treatment because calcite deposits and other fouling of the transducer head are prevented.Furthermore, it is scientifically proven, that frequent cleaning of the transmitter results in a 50% stronger sound signal after 6 months.




LCD Display Module with PushbuttonsAn LCD screen is included in every LG Sonic e-Line that displays the status of each LG Sonic transmitter. The LCD module includes 2 pushbuttons to select up to 10 different frequency programs for each of your transmitters.









Remote control and selection of the optimal frequency programThe GSM-2 Control unit allows you to monitor and change the ultrasonic program of your unit:


  • Thanks to the Chameleon technology, the LG Sonic e-Line has different frequency programs which can be changed by sending an SMS Message.
  • Besides that, you can request the operation status of your device at any time or receive an SMS message.
