摘要： A meter roller for an agricultural metering system includes multiple flutes and corresponding recesses. The flutes and the corresponding recesses are configured to meter flowable particulate material from a storage tank to a material distribution system via rotation of the meter roller. The meter roller also includes multiple air passages formed within a body of the meter roller. Each air passage is fluidly coupled to a central cavity of the meter roller and extends to a base of a respective recess, and the air passage is configured to flow air from the central cavity into the respective recess.

摘要： The present disclosure provides an intake air flow rate measuring device. The intake air flow rate measuring device includes a flange, a casing, a flow rate sensor, a humidity sensing element, an element terminal, and a humidity terminal. The humidity terminal is spaced away from the element terminal. A portion of the casing between the element terminal and the humidity terminal is defined as a suppressing portion, and a cross-section of the suppressing portion is defined as a suppressing portion cross-section. An end portion of the casing close to the flange is defined as a base portion, and a cross-section of the base portion is defined as a base portion cross-section. The suppressing portion cross-section is set to be smaller than the base portion cross-section.
