Proposed is a flow sensor (10), in particular for single use, having at least three measurement chambers (11, 15, 19), which are arranged one behind the other and are interconnected in each case by a flow resistance. At least two of the flow resistances have a different coefficient of pressure loss. A pressure measuring means (12, 16, 20) is provided for each measurement chamber, which pressure measuring means (12, 16, 20) is suitable for measuring the pressure in the measurement chamber. An electromagnetically actuatable valve arrangement (50) can be connected downstream of the flow sensor.

An agricultural implement system is provided including a fluid conduit configured to provide product to a ground engaging tool. The ground engaging tool is configured to deposit the product into soil. 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 measurement system configured to determine a mass flow rate of the product based on a pressure drop between an upstream portion of the fluid conduit and a downstream portion of the fluid conduit, a flow rate of the air flow, and a velocity of the air flow.
