It is assumed that a smallholder is using drip irrigation (either pressurised or gravity feed) on a garden or a small plot of land. Using the Unpowered Measured Irrigation Controller, you can upgrade your drip irrigation system so that all your plants are irrigated automatically. The water supply pressure should be at least 10 kPa (1 metre head). Provided you have a continuous water supply, you can leave your garden unattended for weeks on end. This will allow you to become involved in other activities away from the garden; for example, travelling to the market to sell your produce.

It is recommended that you watch the YouTube video Unpowered Smart Irrigation Controller with float rings.

The Unpowered Measured Irrigation Controller can be used for gravity feed or pressurized systems, sprinkler or drip irrigation, porous hose irrigation (weeper hose or soaker hose), pressure compensating drippers or non pressure compensating drippers.

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 Unpowered MI 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. This is a unique feature of measured irrigation.

The water usage for the Unpowered MI Controller is directly proportional to the prevailing net evaporation experienced by your plants. This is a unique feature of measured irrigation.

The Unpowered Measured Irrigation Controller can be purchased online from the Shop at the Measured Irrigation website:
