Section 3: Wireless irrigation practice
3.1 WIRELESS APPLICATION AND FIELD DESIGN:
The great irrigation systems begin with a great plan. For irrigation automation, three systems merge
together in the eld. It all has to work!
Automation of irrigation requires three systems working together.
(1) the pumping system
(2) the wireless network system.
(3) the irrigation pipe system.
Before beginning a eld design plan for the unplanned. Consider ahead of time some solution for
unusual events that could happen in any of the three systems.
The rst rule of automation is to
plan for a pressure relief valve.
Provide pressure relief to protect the pipe system from bursting due to excess pressure. Unplanned
events do happen and regardless of the cause, the pressure relief will protect the system rather than
damaging the pump and pipes (relief is similar to a fuse protecting an electrical system).
3.2 PLAN THE VALVE LOCATIONS CONSIDERING THE TWIG NETWORK:
The rst thing to do is make a eld map that shows the irrigation system design. Using the map
you can determine the best place for the TD200 controller. Next determine the distances from the
controller to each TWIG valve. Check the line-of-sight and avoid any obstacles. Typically a TWIG-1
model will be needed at each valve.
Consider the use of multi-valve TWIGs
where the valves are close together.
The picture here shows where 4 eld
blocks join together at the corners.
One advantage in this situation is that
one TWIG-4 can operate all four of the
valves separately or altogether at the
same time. The multi-valve TWIG can
be used if the valves are separated only
by a short distance (50 feet or less).
