Testing WVO and biodiesel for water.

Dave
We are just getting round to make our turbo drier.
We are using the cheap eBay humidity sensor.
Can I ask how far above the surface of the bio shots the sensor have to be.
Also what happens if you don't fit a fan? Have you tried this.
Thanks

Hi Paul,

I haven't used my dryer without the fan. The led driver that powers the fan is also in the tub with the air pump so when the dryer is plugged in it starts both the air pump and the fan.

The sensor is positioned about 5 cms above the extraction fan.

If you don't use a fan and rely on the air that is bubbling through the bio to force itself out between the tank top and plywood disk then you will get very different readings to those I did with the sensor over the fan.

The readings are on this thread, post No 36.
