A circular scale is a type of scale that is used to measure the weight of a load in a vehicle, such as a truck or bus. Circular scales are designed to be placed in the ground, and a vehicle is driven over them while the weight is measured. Circular scales are most often used for weighing cargo in the transport industry, warehouses, refineries and other places where cargo is loaded and unloaded.

Circular scales usually consist of two or more circular sensors that are placed under the platform. Sensors read the weight of the vehicle as it drives over the platform, and the results are displayed on a convenient screen.

Circular scales can be integrated with a computer or other devices to enable automatic data recording and processing. Circular scales are very reliable and precise in measuring the weight of loads, and are available in different sizes and capacities to meet the needs of users.
