[Kris] Started the build with a Pelton wheel sourced from everyone’s favorite online auction site paired with an inexpensive MPPT charge controller designed for use with solar panels. Eventually ...

The key to this build is the inclusion of a pelton wheel—which we’ve seen before in a similar build. [Buddhanz1] channeled the water flow directly into the pelton wheel to spin the shaft ...

The design challenge for turbine flow meters, based on the working principles of this type of radial turbine, is primarily straightforward: simple electronics versus complex precision engineering. In ...

Since pumping surges are greater at some of the low flows used by the Pelton wheel, you may want to open a larger flow through another section of the lab. Set the needle valve at a partly open ...
