Aquatrol 1000

In response to the many who have asked "what does it take to make a typical system", we have put together a design for a complete, fully featured status monitoring and control system, which we call the AQUATROL 1000, designed to meet the needs of a 4 tank, commercial aquaculture farming facility.

It's "system" consists of a set of basic components we've found to be the most often specified for a four tank installation (three grow-out tanks, and one make-up tank).

a1000.gif (17181 bytes) Sensors:

The sensor suite includes pH, ORP and temperature for each tank, and a DO sensor, which may be plugged into the MCU500 control unit or used stand alone, to provide on-line monitoring and spot checking of any tank. Each tank is equipped with a level detector probe, consisting of four level float switches that provide indications and alarms for overflow (alarm), normal, low water (for controlling pumps) and low level (alarm).

The suite of sensors and controls includes those that are applicable to the site in general, and are not a function of the number of tanks. These include two air pressure sensors, two air flow switches (for tank aeration systems), air temperature, water flow rate and inlet water temperature. Controls consist of pump, heater, aerator and feeder controls.

Controller:

Each configuration of four tanks uses one MCU500 and an expander box. The MCU 500 is the system controller, and comes complete with 18 dual channel signal interface modules installed.

The expander houses a general purpose signal connection block for wiring out to the sensors, level detectors and other functions. The expander also contains a relay module for controlling up to 16 relays, a 1200 to 19200 baud modem, a 12 VDC power supply for providing power to external sensors and line amplifiers, fan, and a fiberglass watertight NEMA 4 enclosure with see-through front panel.

Easy to use from your preferred workplace:

The MCU500 is a self-contained controller that normally operates stand-alone. It performs alarm monitoring and controls system functions using simple on-off control logic to more complex setpoint functions. When an alarm occurs, it will call your host PC, page you, print an alarm message, or perform whatever action you tell it to.

It may also be controlled from your PC. You can operate the MCU500 from the convenience of your office or home, including reading system parameters, operating switches, setting setpoints, etc. The MCU500 data logging output is fully transportable into all common spreadsheet programs.

And, to make it all come together:

The line amplifiers are dual channel versions, with one channel optically isolated. The optically isolated (also called galvanic isolation) amplifiers are used to interface with ground referenced probes, such as pH, ORP, and other Ion selective probes, which typically come in contact with large grounded bodies of water. The optical isolation provides exceptionally clean signals, eliminating the typical power line ground noise which is usually present and often masks or disturbs the low level signal from the probes. The total isolation also extends the life of the probe, eliminating electrolysis and depletion of probe electrolytes due to system ground currents.

A total of six AC switch modules are provided with the system. Each switch module contains a twin outlet receptacle, integral 40 amp solid state relay, status indicator, Local/Remote/Off switch, and a 6 foot cord with plug. These units are rated at 15 Amp, single phase, 120 or 220 VAC. They are designed for mounting onto a panel board, post, etc., and provide a convenient way of controlling power to feeders, pumps, air compressors, fans, heaters, and more. Larger versions are available.

The AQUATROL 1000 system, as shown, is designed to handle installations of up to approximately 4 tanks each. More importantly, it gives the system planner the option of procuring the components in well defined, not too large, subsets of sensors and controls, with spares. As the installation grows, additional systems are added and networked together. In the multi-MCU configuration, one MCU500 is normally designated the master controller. Typically, this unit is equipped with the modem, or Ethernet port, while the others are not. A second unit can be configured with a modem to provide pager support and communications redundancy.

There is literally an unlimited combination of sensors and controls that the AQUATROL 1000 system, with it's MCU500, can support. Each MCU can be configured with more than one expander unit, increasing the total number of analog channels up to the maximum of 64 per MCU, up to 64 Relay control points, up to 64 digital inputs, and up to 64 digital outputs per MCU. Within these constraints, virtually any combination of sensors and controls can be added, including salinity, photometers, level detectors, control of valves, ORP, Ozone and pH control.. The possibilities are limited only by your imagination.

Programming is very easy, and user friendly. We provide a complete set of tools to create the MCU's database, and to communicate with the MCU to configure it, and control it, from your desktop. You can implement timers to control feeders, setpoints to control pH, DO, aerators, lights, heaters, ventilators, shade cloth, etc.
You can implement alarms, from simple 2 state alarms to more sophisticated 5 state alarms, and prioritize then based on type of alarm, time of day, and any parameter you wish to monitor.

And, as if this weren't enough, the MCU also has a very powerful, yet easy to use script language, which lets you create functions and process control routines as you need them. At your desktop, we also provide you with the tools to communicate with the MCU (by modem, Ethernet, or direct serial), and data capture, and display tools, giving you the capabilities you need to best run your facility.

Price is flexible, based on quantity and types of sensors and controls ordered. For your convenience, we have included a detailed breakdown of the AQUATROL 1000 system price. COS can provide other off-the-shelf components and vendor items to meet your system requirements. We'd be happy to assist you in planning and costing your next installation.
