Kerekszámláló

Kerekszámláló is a Hungarian term that translates to "round counter" or "circular counter". It refers to a type of counter or meter that displays its reading in a circular fashion. Instead of a linear display with digits moving from right to left, a kerekszámláló typically uses a rotating dial or a series of concentric rings that indicate different values.

These counters are often found in older mechanical devices, scientific instruments, and some forms of decorative or antique machinery. The design allows for a compact display of information, and the circular movement can sometimes be visually appealing. Examples include older odometers in vehicles, certain types of timers, or gauges used to measure specific quantities in mechanical systems. The exact mechanism and the number of rotating elements can vary greatly depending on the application and the complexity of the measurement being performed. While digital displays have become more common, kerekszámlálók still hold a place in niche applications and for historical or aesthetic reasons.
