A tool used in surveying to find distances by sending microwaves and measuring how long it takes for them to bounce back.
The engineer used a tellurometer to accurately measure the distance to the construction site.
This word originates from Latin, where 'tellus' means 'earth' and 'metrum' (from Greek 'metron') means 'measure'. A tellurometer is a device that measures distances on the earth's surface.
Think of 'earth' ('tellus') being measured ('metrum') — that's how a tellurometer works.
