Abstract:
1. An agricultural material distribution system, comprising: a material holding bin; a metering system including a container, the metering system configured to deliver material from the container to an agricultural field as the distribution system is transported through the field; a material transport system configured to deliver material from the material holding bin to an opening within an upper portion of the container; a first sensor assembly positioned within a lower portion of the container and configured to indicate a low material level in the container based on physical contact with the material; a second sensor assembly positioned within the upper portion of the container and configured to indicate a substantially full material level in the container based on physical contact with the material; and a controller communicatively coupled to the first and second sensor assemblies and configured to operate the material transport system in response to output from the first and second sensor assemblies: wherein each pressure sensor assembly is substantially sealed and includes a filter configured to block material form entering the sensor assembly.
