How We Can Help You

Campbell Scientific systems perform automated monitoring, control, and alarm functions in recirculating, flow-through, and open-pond aquaculture. Our systems measure input from water-quality, flow, and amp sensors, and control aerators, pumps, alarms, and communication devices. These systems can be configured to serve the smallest to the largest aquaculture enterprises. Learn more

Automated weather station on Mount Everest

The Same Hardware Installed on Mount Everest

The Campbell Intercept™ CCT AWOS solution is based upon the same weather station hardware that is used to withstand the harshest of conditions on Mount Everest. The weather stations installed on Mount Everest are the highest in the world. Visit the Everest Project web pages to learn more.

Campbell Intercept™

Aviation INTERCEPT software

Campbell Scientific is proud to introduce our newest generation Automated Weather Observing System (AWOS) software, Campbell Intercept™. Campbell Intercept™ combines modern features and functionality with the flexibility and reliability desired by today’s airports. It has been designed to provide International Civil Aviation Organization (ICAO) and World Meteorological Organization (WMO) compliance within a flexible framework that is sensor agnostic, highly configurable, and can be modified to meet local in-country requirements.

Campbell Intercept™ provides web-based clients for many user profiles, including air traffic controllers, meteorological observers, maintenance personnel, and system administrators.

Campbell Intercept™ software can run on Windows or Linux-based operating systems. It has been designed to meet modern aviation stakeholder requirements related to security and software assurance.


We offer a variety of products that can be used to create systems for Aquaculture. Many of the major components used to create these systems are listed below. Please let us know if we can help you configure a system.

More Details about Our Aquaculture Systems

Continuous System Monitoring

Our systems monitor and record water quality around the clock providing continuous data that can be used to identify trends and improve production. Almost any sensor can be used, including dissolved oxygen, temperature, pH, conductivity, salinity, turbidity, ORP, ammonia, flow, and level. Sensors can measure and store data at any interval you choose. Through the use of mathematical algorithms, you can store processed data in the units of your choice, simplifying data analysis.

Automated Control

Aerators, pumps, alarms, or other electrical devices can be controlled based on measured conditions or time. For example, aerators can be turned on (day or night) when DO measurements reach a preset value. Together with continuous monitoring, automated control keeps your system operating efficiently even when you are not around.


The availability of multiple communications options for transmitting data to the central computer also allows systems to be customized to meet exact needs. Options include radio, telephone, cell phone, voice-synthesized phone, satellite, and Ethernet. Systems can be programmed to send alarms or report site conditions by calling out to a computer, phones, radios, and/or pagers.

System Reliability

Our measurement and control units have proven their reliability in thousands of applications in climates worldwide making precise, reliable measurements on a wide variety of sensors. Since rechargeable batteries are used as a power source, systems can continue to measure and store time-stamped data and control on-site generators and other devices during power outages.

Pond Measurements

In ponds, our systems typically monitor dissolved oxygen and temperature. Amps or RPMs can also be monitored on motors to aid in detecting aerator failures. In a pond monitoring system, a CR1000 measurement and control unit (or other unit), housed in an environmental enclosure, measures sensors and controls aerators based on preset times or based on the concentration of dissolved oxygen, as measured by the sensors. Alarms are sent via pager, radio, or phone when oxygen levels reach preset danger levels or when amp or RPM sensors indicate aerator failure.

Recirculating Operations

A CR1000 (or other control unit) monitors dissolved oxygen, pH, temperature, flow, level, and other sensors. Based on those measurements (or preset times) valves, pumps, chemical injectors, aerators, and other devices are controlled to maintain appropriate water quality and quantity for the aquaculture operation. The control unit, its power supply, and communication devices are housed in an enclosure. Data is transmitted to the central computer for analysis. Status of the recirculating system can be monitored from the central computer.

Frequently Asked Questions

Number of FAQs related to Aquaculture: 3

Expand AllCollapse All

  1. Yes. Campbell Scientific monitoring and control systems are used in many applications. They can be programmed to monitor and control any application.

  2. Because each farm is unique in its configuration, each system is designed to meet the needs of the farm. Contact Campbell Scientific to develop a customized solution. We can also recommend very capable system integrators to handle the installation of a system.

  3. Oxygen is controlled in water by forcing oxygen into the water. There are typically three ways to accomplish this:

    1. Place a paddle-wheel type device that mixes the water so that more water comes into contact with the air. This process is used in open pond systems. This can only increase the amount of dissolved oxygen in the water to be in equilibrium with the atmosphere.
    2. Force pressurized air (or pure oxygen) into the water with diffusers.
    3. Allow the water to free fall through the air. This process releases any over-saturated gases and increases the surface area of the water so that more dissolved oxygen in the area can be exposed to the water. Control the mechanical equipment that forces more oxygen into the water. In open ponds, this is traditionally done by turning on paddle-wheel aerators. In closed re-circulating tank systems, this is done by turning on additional aerator pumps.
