How about Coal Meter? I found this regarding a description of Coal Whippers.
"It is carried on by gangs of nine, four work in the hold of the ship and fill the basket, four work on the ways, and whip the coal—that is, raise the basket to the top—and one, the basket man, turns it into the meter’s box."Previously, this individual was described as a coal labourer or coal whipper. In 1881 he was described as a coal weigher, and coal meter seems to be another description for that job:
Coal-meter: usually a London based occupation, a licensed official responsible for measuring coal.Edit: tonepad - you replied whilst I was typing. Thank you both. I'm happy with coal meter
