Universal Measured Irrigation Controller

It is recommended that you watch the YouTube video Universal Measured Irrigation Controller (not available yet)

Adjust the water usage (litres per week) by adjusting the control dripper

 

Adjust the irrigation frequency by adjusting the float

 

A cylindrical float and eight float rings are provided

 

 

The Universal Measured Irrigation Controller can upgrade your programmable irrigation controller or tap timer so that the water usage (litres per week for example) is significantly reduced without affecting the yield or the health of your plants. The Universal Measured Irrigation Controller can also be used a stand-alone irrigation controller.

​

For programmable irrigation controllers, one of the disadvantages of non pressure compensating drippers is that the water usage is affected by variations in the water supply pressure. With the Universal Measured Irrigation Controller the water usage is independent of the water supply pressure. If fact the water pressure can change significantly during the irrigation event without affecting the dripper discharge volumes.

​

​

  • Use with a tap timer, a programmable irrigation controller, or use as a stand-alone irrigation controller​

 

  • Completely automatic

​

  • Smart irrigation controller – the irrigation is controlled by the prevailing weather conditions rather than a program

​​

  • Use for both gravity feed and pressurised irrigation

​

  • Use for any size irrigation system regardless of the size of the solenoid valve

​​

  • Use for sprinkler or drip irrigation

​

  • Use for weeper or soaker hose irrigation​

​

  • Use for pressure compensating drippers or non pressure compensating drippers.

​​

  • You can adjust the water usage by adjusting the control dripper

​​

  • You can adjust the irrigation frequency by adjusting the float

​​

  • Adjusting the control dripper does not change the irrigation frequency

​​

  • Adjusting the float does not change the water usage

​​

  • The water usage is directly proportional to the net evaporation rate (a unique feature of measured irrigation)

​​

  • Respond appropriately when there is an unexpected heat wave

​​

  • When it rains, water enters the evaporator and delays the start of the next irrigation

​​

  • The water usage is independent of the water supply pressure (a unique feature of measured irrigation)

​​

  • Uses much less water without affecting the yield

​​

  • Simple and low tech and so there are fewer things to go wrong

​

By using a zero pressure solenoid valve and the Universal Measured Irrigation Controller, you can irrigate directly from your rainwater tank without a pump. The water usage for measured irrigation is controlled by the prevailing weather conditions and is independent of the water level in the tank. The Universal Measured Irrigation Controller is a game-changer for automated irrigation from a rainwater tank (or header tank) without using a pump or timer. Low pressure means that hose clamps are not needed.

Connect the blue and green wires to the solenoid valve connected to a tap timer.

 

Connect the 4 wires in the blue cable to the appropriate terminals in a programmable irrigation controller.

 

Sunset Measured Irrigation Controller

Sunset Measured Irrigation Controller

The Sunset Measured Irrigation Controller is simply the Universal Measured Irrigation Controller without the adjustable float and associated water supply. It is the appropriate choice of irrigation controller for plants with a shallow root zone or plants in sandy soil.

​

If you are using the Sunset MI Controller as a stand-alone controller, set the switch on the control box to the ON night only position. The irrigation will start at sunset provided that the water level is below the float switch. If the switch is in the ON position, there will be multiple irrigations during the day each with a small amount of water.
