For my last project I made my own water level out of clear flexible
hose. I don't know why but I found it difficult to get consistent
readings and difficult to prop up both ends of the hose.

You need to mark off graduations from the end of the hose and proper
use requires two people, however there are factors such as parallax
and surface tension that render such a device inaccurate... at best
it'd give a rough approximation.

That's what led me to the string level.

A string level is fine if you want to set something approximately
level but is pretty useless for determining pitch.
