Understanding Net Weight Filler Configuration and Performance

While many filling technologies exist, gravimetric or net weight fillers remain a predominant fill method in the CASE industry. These fillers utilize a scale to measure the precise amount of product dispensed to a container. They have replaced other fill methods due to their ease of automation, flexibility to handle multiple container sizes and varying product densities, and ability to maintain accuracy even with products containing entrapped air.

Net weight fillers are supplied in both automatic and semi-automatic configurations. Semi-automatic fillers feature one or two fill heads. During semi-automatic operation, the operator places containers under each fill head. A button is pressed to initiate fill, and fill stops when the targeted weight is reached. The operator removes the filled containers, and the process begins again.
