A belt scale is an automatic weighing instrument capable of continuously weighing bulk materials without stopping the conveyor belt, mainly calculating the cumulative flow by detecting the of the material on the belt and its running speed. It is widely used in industries such as mining, metallurgy, and electric power, replacing traditional batch static weighing to make production metering continuous.

How does it calculate weight?

The core logic of a belt scale is actually very simple: "weight × speed = flow". The weighing sensor detects the of the material passing through the metering section, and the speed sensor captures the running speed of the belt. These two signals are sent to the meter for integral calculation, which can display the flow and cumulative weight in real time. Modern electronic belt scales have replaced old-fashioned mechanical roller scales, offering more accurate signal processing and the ability to transmit data remotely.

How choose the right model

Model selection mainly depends on accuracy requirements and material characteristics. For general process control, an economical model with an accuracy of ±0.5% to ±1 is sufficient. If it is for trade settlement or high-precision batching, a high-precision model with ±0.25% or even ±0.1% accuracy must selected. Structurally, suspended and multi-roller types are more stable in accuracy due to their longer metering sections and strong anti-interference capabilities, making them suitable for high-flow. Speed-regulating belt scales can also control the feeding amount via variable frequency, making them suitable for batching processes that require a constant flow
