Often, meters is meters. D'Arsonval meters are typically used in
circuits for measuring volts or amps. the same meter can do either or
both depending on the circuit it is used with. While the meter movement
itself might require 50. 100 or whatever micro amps for FSD ( full scale
deflection) the other circuit elements determine its function.

I can see a clever use of crossed needles in a PA to display "DC power
input to the final", which might be of dubious usefulness given the
modern PEP style power limit, but would have been the hot ticket back in
the day.
ANother clever use would be to create a faceplate that has "safe
operating area" marked on it.
