The electric versions of these instruments are extremely simple, nothing
like as complex as the tach or speedo, consisting of little more than a coil
of wire wrapped round a bi-metallic strip connected to the pointer. Each
end of the strip is connected to a post connected to the back of the case
and has a screw-driver slot in it, which can be turned to calibrate the
gauge for full and empty.
