Dasymeter

A dasymeter is a device used to measure the amount of electricity flowing through a wire. It helps to tell us how much electricity is being used in a household or building. The dasymeter works by measuring the amount of current (the flow of electricity) that is coming in and going out of the wire. It has an electrical meter that is connected to the wire and it keeps track of the current so that we can see how much electricity is being used.
