An agricultural implement system is provided including a fluid conduit configured to provide product to a ground engaging tool. The agricultural implement system also includes an air source fluidly coupled to the fluid conduit, and configured to provide an air flow through the fluid conduit in a downstream direction toward the ground engaging tool. The agricultural implement system further includes a product delivery system fluidly coupled to the fluid conduit, and configured to transfer the product into the air flow. In addition, the agricultural implement system includes a product flow control system configured to determine a mass flow rate of the product based on a pressure drop through the fluid conduit, and to adjust product transfer into the air flow based on the determined mass flow rate of the product.
