DIY Unpowered Evaporative Valve Kit

It is recommended that you watch the YouTube video DIY Unpowered Measured Irrigation Controller Kit


The Kit has everything you need except for the evaporator


Fully assembled DIY Unpowered Evaporative Valve

  • 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

The DIY Unpowered Evaporative Valve Kit can be purchased online from the Measured Irrigation Shop.
