Smart aquaculture systems

 SENECT developed the technology which allows the control of all processes in fish farms!

The modular control system consists of sensors, which measure water quality and quantity parameters, control units, which process the sensor information and act accordingly and acutators, like valves, filters or feeder which execute these actions finally. Standing above all, the user has access to all the measurement values, current states and controls all processes in real-time on his smartphone, tablet or PC.

Due to its flexible modular architecture you can select your own individual set of sensors, controllers and actuators and bring all toghether in one software app. The plug-and-play connectors allow the straightforward installation and makes it therefore easy for you. The decentralized modular architecture brings substantial advantages:

  • Extension or reconfiguration of the system always possible
  • Efficient task execution: for every task the perfect fitting control unit and powerful algorithms
  • The tasks were executed directly at its location - data is transferred wireless and therefore less cables are needed
  • Enhanced security due to seperated functional units (in contrast to monolithic centralized systems where one error can cause the shut down of the entire system)
  • Additional cost-savings possible due to easy and fast installation - also for non-electricians

SENECT offers beside the sensors and controllers also perfectly fitting components (actuators) like solenoid valves, automatic fish feeders or drum filters. But the SENECT control units offer you also the freedom to connect actuators from third party suppliers.

What is possible with the SENECT control system? - Nearly everything!

With the SENECT control units and the corresponding components like valves, pumps, filters or feeders you can enhance your exisiting aquaculture system or equip an entire new one to benefit from the advantages and strength of the SENECT control system.

The typical control tasks, what is needed in fish farms, are often the same. That´s why we developed intelligent and powerful functions - embedded in the SENECT control units - which execute these tasks. Examples for these functions are:

Online-monitoring and alarming of water parameters (e.g. O2, water level)
Every SENECT control unit can be connected with a WLAN (wifi) network. On the one hand, this enables you to use the SENECT control app to get direct access to the current measurment values, the data record, or the settings. On the other hand, alarm messages can be sent via push messages or emails, e.g. when parameters exceed or fall below thresholds.

Control of aeration
Long-term stable measurements with the optical O2S oxygen sensor make it possible to switch on the aeration only, when this is necessary. This saves energy and therefore directly reduces operation costs. Additionally, mechanical wear out is reduced and (depending on the aerator type and system) – also the pH effect of aeration (CO2-degassing) is minimized.

Automatic fish feeder control
The SENECT control units are equipped with a powerful fish feeder menu:

  • Different time modes (e.g. at fixed times or in defined intervals)
  • Calibration possible: displaying the feed amount in (kilo)gramm / defining a daily ration
  • Oxygen: No feeding if the oxygen level is too low
  • In combination with oxygen dosing: increase oxygen concentration before the feeding starts
  • Temperature depending feeding (according to the data sheet of your feed supplier)

Oxygen dosing
If pure oxygen is used for the oxygenation, the exact dosing is essential to avoid fish health problems caused by over- or underdosing. The exact addition of oxygen can be controlled by the optical oxygen sensor O2S, solenoid valves and e.g. ceramic diffusors.

Drum filter control
The FILTER|CONTROL and the AQUACULTURE|CONTROL units can be used to control drum or belt filter. With its embedded intelligent control algorithms and reasonable settings, they enable a trouble-free and extreme reliable filter operation. Additionally, unnecessary mechanical wear-out is reduced, water- and energy-consumption minimized and manual maintenance intervals elongated – compared to the typical filter operation.

Some of the functions are:

  • Start of flushing induced by clogging of the filter mesh, compensated for water level changes of the aquaculture system
  • Intensive cleaning programme
  • EcoMode: saving up to 50% of water and energy
  • Intelligent emergency switch-off

Pump surveillance and emergency switch off
The measurement of the water level e.g. with the SENECT water level probe PS can also be used to monitor the hydraulic functioning of your system. With this information, it can be detected, when a pump stopps its operation or if the water level is too low, the pumps can be switched off to avoid damage due to the dry-run.

Ozone reactors need for their optimal operation the control of the ozone addition. By the measurement of the oxidation-reduction potential with the ORP sensor XT-1 this task can be fulfilled with the SENECT control units. Additional protection mechanisms like a maximum duration of the output port lead to a safe operation. 

Beside these "typical for aquaculture" tasks, the SENECT control units can also be used for individualized regluation and control tasks. For example:

    • Individual switch on / off of output ports based on sensor measurements
    • Time controlled output activation
    • Switching output ports in relation to other output ports
    • Giving alarm signals also to other devices

Thanks to these versatile features, the SENECT control units can fulfill nearly every task in aquaculture systems.

The information of all your control units can be combined in one software, e.g. on your smartphone, tablet or PC. You have always the overview about the current status and measurement values. You can also see, what tasks were executed in the past and the data record can be visualized.
