An agricultural implement system is provided including a fluid conduitconfigured to provide product to a ground engaging tool. The ground engagingtool isconfigured to deposit the product into soil. The agricultural implement systemalsoincludes an air source fluidly coupled to the fluid conduit, and configured toprovidean air flow through the fluid conduit in a downstream direction toward thegroundengaging tool. The agricultural implement system further includes a productdeliverysystem fluidly coupled to the fluid conduit, and configured to transfer theproduct intothe air flow. In addition, the agricultural implement system includes aproduct flowmeasurement system configured to determine a mass flow rate of the productbasedon a pressure drop between an upstream portion of the fluid conduit and adownstream portion of the fluid conduit, a flow rate of the air flow, and avelocity ofthe air flow.
