Volumetric feeders are typically?

Volumetric feeders are generally less expensive to maintain than gravimetric feeders because they operate on a simpler principle of measuring volume rather than weight. Their design involves straightforward mechanisms that do not require as many intricate components or regular calibration procedures related to weight measurements. This simplicity often translates to lower maintenance costs, as fewer parts may wear out or require replacing over time, and there is less need for adjustment or recalibration compared to gravimetric systems, which depend on precise weight measurements. Since volumetric feeders do not measure the weight of the material being fed, they often use less sophisticated technology and fewer sensors, which also contributes to reduced operational costs. The ease of maintenance and fewer parts required for accurate regulation make volumetric feeders a more cost-effective option for many applications in water treatment and other industries.
