**********************
The "Beutenkarl" scale
**********************
A scale for measuring hive weight is probably the most important tool
when looking for insights into bee colony behavior by beehive monitoring.


Introduction
============
We have a classic double-H formed scale frame enclosing a
`Bosche H30A single point load cell`_ by Karsten Harazim
and Robert Gummi of `Beutenkarl`_ fame (`facebook <Beutenkarl at Facebook_>`_).
