What does measurer mean?
A measurer is someone or something that determines a quantity by comparing it with a standard. In its first sense, the word refers to a person whose job is to measure, such as a land surveyor or assessor. In its second sense, it refers to an instrument, including a ruler, gauge, or specialized measuring device. The word is broad and somewhat formal, so speakers often choose a more precise term when one is available. Its usefulness lies in distinguishing the entity doing the measuring from the measurement itself and from the unit or standard being used. A measurer can be an essential tool in construction, science, manufacturing, navigation, and many other activities where reliable quantities are needed.
