A filter element is removably positionable within a filter housing that includes a standpipe extending therewithin and provided with a flow control valve. In one embodiment, a method of fabricating a semiconductor device includes providing a substrate having a frontside surface and a backside surface, and forming a plurality of sensor elements in the substrate, each of the plurality of sensor elements configured to receive light directed towards the backside surface. Also provided is a series connection configured with a choke coil and a first switch and connected to the terminal point. The controller is communicatively coupled to the valve, and is configured to determine the seed frequency of the first and second seed meters based on a speed-related parameter of the planter.
