[RE-wrenches] Micro Hydro control

[Carl Emerson]

Hi there gang,

 

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. 

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.

We are planning a 6inch pipe with around 100 ft of fall, the stream when low
will allow a flow of 20Litres/sec but when high will deliver twice that
amount.

Any suggestions??

 

Thanks
