Hi,

I have 2 dials I would like to keep and eye on.
These are pressure dials for the heating system.
All mains water pressure heating systems loose pressure over time.
I would like to know when the pressure drops without going outside to read the meters.
How could I digitise the reading of the two attached dials?

Two images attached.

Get some sort of digital pressure sensor that you can put in parallel with or in place of said dial gauges. 
If at first you don't succeed, up - home - sudo - enter.

As an aside , the pressure should hold up for many months or you've a leak !

When the pressure falls right down the boiler won't run.

- you might have some luck with a reflective sensor on the gauge , but a seperate pressure transducer or pressure switch is the way to go, as suggested above
