Claim:
1. A system for measuring product flow to an agricultural implement, comprising: a first pressure sensor configured to output a first signal indicative of fluid pressure within an upstream portion of a fluid conduit, wherein the fluid conduit is configured to convey product to the agricultural implement via an air flow in a downstream direction; a second pressure sensor configured to output a second signal indicative of fluid pressure within a downstream portion of the fluid conduit; an air flow sensor configured to output a third signal indicative of a flow rate of the air flow, and a fourth signal indicative of a velocity of the air flow; and a controller communicatively coupled to the first pressure sensor, to the second pressure sensor, and to the air flow sensor, wherein the controller is configured to determine a pressure drop between the upstream and downstream portions of the fluid conduit based on the first signal and the second signal, and the controller is configured to determine a mass flow rate of the product based on the pressure drop, the third signal, and the fourth signal, wherein all signals are conveyed to the controller when product is in the fluid conduit, and wherein at least a portion of the product is a particulate.
