The pneumatic conveying system includes first delivery line operably connected to an airflow source and to the supply compartment, and a second delivery line operably connected to the airflow source and to the supply compartment. The metering system includes a first metering device associated with the first delivery line and a second metering device associate with the second delivery line. The controller controls the air flow source, the first metering device to meter product to result in a first mixed flow of airflow and product for the first delivery line, and the second metering device to meter product with the airflow to result in a second mixed flow of airflow and product for the second delivery line.

A valve with permanent magnet(s) and electro-magnet coils magnetically coupled to the permanent magnet(s). The valve is positioned below an inlet for receiving media. The amount of media flow may be regulated by controlling the current to the coils for partial or full flow. With no power applied to the electro-magnet coils, the media flow is inhibited. Application of a current to the electro-magnet coils will block the flux in the pole pieces rendering the working gap free of magnetic flux and thus allowing media to freely flow. As it is used, the media may become magnetized, altering the flow properties and causing magnetized media to bridge across the working gap. A magnetic sensor detects the amount of flux in the working gap to provide a signal to a control system. The signal allows closed loop control of the coils as media becomes magnetized, allowing consistent flow properties during use.

Assembly for regulating flow of hops into a fermentation vessel includes a hollow cross-shaped connector including a first cylindrical housing intersecting a second cylindrical housing at an approximate right angle. A rotary shaft coaxially mounted within the first cylindrical housing supports a hub and uniformly spaced vanes at a proximal end with outer ends of each vane adapted to sweep in close engagement with an inner wall of the first cylindrical housing. An actuator coupled to a distal end of the shaft is configured to control rotation of the shaft to control flow of hops from a hopper configured for holding hops into a hatch of a fermentation vessel configured for holding fermenting fluid. An outlet of the second cylindrical housing sealably connects to the hatch of the fermentation vessel, and an inlet of the second cylindrical housing sealably connects to an aperture of the hopper.

A method for controlling a material flow rate from a metering system, includes determining, via a controller, a change in weight of material in a storage tank. The method further includes determining, via the controller, a swept area of an agricultural implement associated with the change in weight based at least in part on a width of the agricultural implement and a change in position of the agricultural implement. Further, the agricultural implement is configured to receive the material from the storage tank. The method also includes determining, via the controller, a calibration of the metering system based at least in part on the change in weight and the swept area. In addition, the method includes controlling, via the controller, a rotation rate of a meter roller of the metering system based at least in part on the calibration to control the material flow rate.

An air cart for use in an agricultural air seeding system is provided. The air cart includes a first storage compartment for holding a first granular product type. The air cart also includes a second storage compartment for holding a second granular product type different from the first granular product type. The air cart further includes a common conduit configured to receive the first granular product type from the first storage compartment and the second granular product type from the second storage compartment to enable simultaneous flow of the first granular product type and the second granular product type. The air cart even further includes a multi-product particle flow rate sensing system configured to monitor respective flow rates for both the first granular product type and the second granular product type during simultaneous flow of the first granular product type and the second granular product type through the common conduit.

Metering devices for an agricultural implement are provided for applying a field input, for example, pneumatically delivered granular product including seed or fertilizer or sprayed liquid product including fertilizer and the like, to an agricultural field. In the applying of the field input, the rate of application of the dispensers of one section of the implement can be collectively varied in relation to the rate of application of the dispensers of a different section of the implement frame.

A plant or refinery may include equipment such as condensers, regenerators, distillation columns, pumps, slide valves, or the like. Different operating methods may impact deterioration in equipment condition, thereby prolonging equipment life, extending production operating time, or providing other benefits. Mechanical or digital sensors may be used for monitoring equipment to determine whether problems are developing. Specifically, sensors may be used in conjunction with one or more system components to predict and detect slide valve hot spots. A shielded, tube skin thermocouple assembly may provide a temperature profile for a slide valve. Tomography may be used to image a slide valve. An operating condition of the plant or refinery may be adjusted to prolong equipment life or avoid equipment failure.
