font-family:Arial'>We are looking at a 4kW PM hydro for a client and was
wondering if anyone has done an automated control of flow into such a unit so
as to limit the amount of water being taken from the stream in the Summer. </span></font></p>
<p class=MsoPlainText><font size=3 face=Arial><span style='font-size:12.0pt;
font-family:Arial'>This is usually done manually by closing down nozzles on the
unit but here in NZ weather changes fast and the unit is 500M from the house.
Summer rains can be significant and sudden.</span></font></p>

stream when low will allow a flow of 20Litres/sec but when high will deliver twice
that amount.</span></font></p>
