Water Control, Weir & Gates

Two gates on each ide of this canal & weir structure are remotely operated for Flood Control purposes.  A headwater and tailwater gauge assists with monitoring the status of the incoming water.

Water Control, Overshot Gates

Flows-OP72.jpg

These six overshot, also called tilting weir, gates are all controlled separately with Campbell data loggers.  With advanced "Super Two-Way" programming, they are subject to one of two operational modes; "Gates Rule" or Flows Rule".

With Gates Rule, an operator can move them to any position and they will stay put.

In Flows Rule, the operator sets a flow that is desired, say, 500 cubic ft / sec., and any one gate, or combination of gates, will pass those flows continuously.  With the system reading the upstream and downstream water levels, the flows are constantly calculated and the gates move by themselves to maintain any desired flow.

 

Pump Stations

Pumps can also be Two-Way operational.  Generally controlled by upstream water levels, these systems will monitor that and start pumps at certain levels.  If levels continue to rise, another pump, then another, will turn on in sequence.  The duration of pumping can be controlled as well, for instance 12 hours ON then 2 hours OFF.

Campbell programming is flexible enough to help with balancing the usages of each pump.  When one pump is needed, the program can determine which is the "youngest", with the least hours of use, and turn that one ON first, then the next youngest, etc., etc  Conversely, if several pumps are running and water levels drop to the first OFF level, the pump with the most hours can be turned off first.

 

As we say in a few places of this web site, there is basically no limit to what the Campbell programming can offer your systems.  If you can think it, we can do it!

Weather Stations

The Campbell system can interface with many, many, kinds of weather sensing equipment.  The system above monitors conditions at 300 ft up a tower to assist with mosquito control spraying.  All SCADA systems are intended to give operators information that is needed for decision making.  In this case, if conditions are not optimal, spraying of expensive chemicals would cost money but produce no results.

 

The graphic above is an example of the Campbell RTMC system (Real Time Monitoring and Control) HMI.  Any information entering the Campbell gear can be represented by this type of "pretty" graphical picture. 

Water & Air Quality

Most agencies are concerned with the quality of water, air, or both, and are funded to monitor them.  Campbell can monitor and analyze these parameters for you.

Types of Installations

IMG_4674.JPG

Any area can get equipment installations.  This is a stand-alone system, running only on battery power that is charged by a solar panel.  The Campbell instruments have been refined over the years to be low power consumers, so small installations like these can run from solar power only.

Battery / Solar Only Installations

If commercial power is not available, remote sites can still be outfitted with monitoring devices.  Keeping a battery charged with a solar panel is easy in Florida!

Three-Mast Installations

Some sites may need to be self supporting, and we've found a three-posted structure provides all the support needed.

Staff Gauges

Any site that must observe and report water levels must have accurate datum information.  Survey information must be available at or near the site, so that staff gauges can be calibrated to represent precise levels.  The data logger system will have to be set to these observed levels when maintenance is performed.

Here are many other pictures of various systems and configurations to review.
