Mêler

Måler is a term used in Danish and Norwegian to denote either a measuring device or a person who measures. It derives from the verb måle, to measure. As a noun, måler can refer to an instrument that quantifies a quantity, such as an electricity meter ( elmåler ), a water meter ( vandmåler ), or a gas meter ( gasmåler ), as well as other measurement devices like multimeters or thermometers when used to quantify physical quantities.

As a person, måler can mean a measurer—someone who performs measurements—such as a surveyor or a field technician who conducts measurements in construction or manufacturing. In everyday language, the device sense is the more common reference, particularly in utilities and home equipment.

In utility contexts, a måler records consumption or usage for billing and monitoring. Modern versions are often digital and may be called smart meters, capable of transmitting data remotely and integrating with home automation systems. The term is also used in broader metrology to describe devices that are calibrated to standard units and used to verify quantities in science and industry.
