Your alcoholometer is placed in the body of the parrot.
Distillate runs from your take-off and is collected in the tale of the device. Designed to flow from the bottom up of the parrot's body and causing the alcoholometer to float.
Distillate fills the body and over-flows down into the beak of the device. Your collection vessel is positioned under the beak.
Reading the alcometer is easy in a parrot, the distillate overflows and you simply read it at the level of the overflow.
This allows you to measure the percentage of alcohol on the fly.
