The black with white digits are the whole number. Between those and the red digits there will probably be a decimal point marked on the meter. So you write those down thus:- WWWWWWW.RR
The dial with arm is for test/diagnostic purposes. However sometimes an extra dummy digit needs to be inserted between the right most red digit and sometimes not. The need for a dummy number to be inserted will be indicated by a painted on '0'.
An arrow indicates the direction of rotation of the dial. The dial reads from 0 to 1, 0 and 1 being co-located at the top of the dial with a 0.5 at the bottom and eight intermediate markers - the value of which have to be worked out.
Lacking the painted on '0', ten rotations of the arm will cause the right most red digit to increment by 1. With the painted on '0' the arm will rotate one hundred times before the red digit increments by one.
If I get a card left by British Gas then all that is needed is to copy down what the gas meter display shows.
OTOH what I want is an accurate reading from the meter in order to track my gas usage.
The meter is made by Parkinson Cowan. It is halfway between these two

is a bit like the very last meter at the bootom of

but with the second 9 changed for a fixed zero.
Have another read of my original posting to see what I mean ...
--------------- ORIGINAL POSTING ------------------ I have a gas meter which is a bit like this one:

on my meter the red digits look different. After the white digits, I have go this:
(a) one red digit (b) a zero printed on the meter (c) a dial (like a clock face) with an arm which goes round clockwise. The dial says 0.5 at 6 o'clock and 1.0 at 12 o'clock.
How do I read these red digits?
I can not find the link between the arm rotations and the final white dial.
------------- END ORIGINAL POSTING ------------
The main problem is that some of the digits behind the decimal point don't seem to be all there.
The printed zero is the weird thing on the display because it almost suggests that the clockface dial has to do 100 revolutions for the previous red digit to advance!
yes I don't have gas at home, and was basing the "6" on a factory unit that I regularly have to read and fitted with an R5 the same as the OP posted a link to.
