Completely automatic

No electricity is needed (no batteries, no solar panels, no computers, and no electronics)

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

Use for gravity feed or pressurised irrigation (water pressure at least 10 kPa)

Use for sprinkler or drip irrigation

Use for pressure compensating drippers or non pressure compensating drippers

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

You can adjust the irrigation frequency by adjusting the float

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

Respond appropriately to an unexpected heat wave

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

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

Uses much less water without affecting the yield

Simple, low tech and easy to assemble and therefore fewer things can go wrong

You can leave your irrigation application unattended for weeks on end
