新概念3里“It's only me”那科的metre是不是印错了?

新概念3里“It's only me”那科的metre是不是印错了?
'Mrs.Richards realized that it must be the man from the Electricity Board who had come to read the "metre".'
明明是指电表的意思,可是电表不是meter吗?metre什么时候有表的意思了?

metre是British English(英式英语)的写法.
meter是American English(美式英语)的写法.
两者实际上只是用法习惯问题,没有错误.
