mõõtevarras

Mõõtevarras is an Estonian term that translates to "measuring rod" or "dipstick" in English. It refers to a tool used for measuring the level of a liquid within a container. The most common application of a mõõtevarras is in vehicles, specifically for checking the oil level in an engine.

A typical mõõtevarras is a slender metal or plastic rod, often with a loop or handle at one end and markings or a graduated scale at the other. The rod is inserted into a tube or opening that leads to the liquid reservoir. When removed, the liquid level on the rod indicates the amount of liquid present. For engine oil, the mõõtevarras usually has two marks, representing the minimum and maximum acceptable oil levels.

Beyond automotive use, mõõtevarras can also refer to similar measuring devices for other liquids, such as fuel tanks, hydraulic systems, or even industrial vats. The principle remains the same: a simple, direct measurement of liquid volume or depth. The design of a mõõtevarras can vary depending on the specific application, but its fundamental purpose is to provide a quick and easy way to ascertain the liquid level.
