Depending on the recipe, a number of raw materials can be fed to the process by Smart Flow Meters. Feed rates often range between 10,000 and 20,000 kg/h [22,000 to 44,000 lb/h] but can also be significantly higher. Material supply to the flow meters can be accomplished by screw feeders or rotary valves, for example.

Metering feeders can work in two ways. First, both are designed to measure and control the flow of materials in different ways. 1. Mass flow meters. Mass flow measures the amount of a substance passing in a given space. A sensor emits a wavelength through the passage where substances flow. This measures how long it …

A feeder is essential for controlling the flow rate of bulk solids from silos, bins, and hoppers. The feeder is an integral part of a storage system because it can have a major impact on the flow pattern in the storage vessel – it can either maintain reliable material flow or induce poor flow, segregation, or flooding of fine powders. Proper selection of a …
