Florida Drinking Water Operator "B" Practice Test

True or False: Gravimetric feeders are generally more accurate than volumetric feeders.

1. True

2. False

3. Depends on the specific situation

4. Only in larger operations

The correct answer is: True

Gravimetric feeders are designed to weigh the material being fed rather than measure the volume. This method utilizes a scale to ensure that a precise amount of material is dispensed based on weight, which is inherently more accurate than volumetric feeders. Volumetric feeders measure the quantity based on volume and can be affected by variations in material density, changes in material flow properties, or equipment calibration errors. The gravimetric approach accounts for these variations by focusing on weight, leading to a controlled and consistent feed rate. This is particularly crucial in applications where the accuracy of the feed directly impacts the quality and consistency of the final product. Therefore, the assertion that gravimetric feeders are generally more accurate than volumetric feeders is accurate due to the fundamental difference in how each type measures the feed material.
