That's an interesting problem.
There are inexpensive gauges (mechanical) that screw into
the tank top and have large readouts.
For an indoor remote readout, there is a manometer gauge;
they are not cheap.
Some electronic gauges today also.

GOOGLE: oil tank remote gauge
or something similar.

Google mainly comes up with commercial gauges or tanks fitted with remote
gauges. Trying to find one on its own is a bit of a problem. But a chap
from another group gave me the name of a company that does them for domestic
use.

Thanks for replying :O)
