摘要：
A pneumatic distribution system for distributing a granular product to an agricultural implement includes a first pressure sensor, a second pressure sensor, a valve, and a controller. The first pressure sensor is fluidly coupled to a storage tank that stores the granular product and outputs a first signal indicative of a first static pressure in the storage tank. The second pressure sensor is fluidly coupled to a meter housing and outputs a second signal indicative of a second static pressure in the meter housing. The valve is fluidly coupled between the storage tank and the primary line and selectively enables the air stream to flow from the primary line to the storage tank. The controller is communicatively coupled to the first pressure sensor, to the second pressure sensor, and to the valve. The controller instructs the valve to enable the air stream to flow from the primary line into the storage tank until the first static pressure is greater than the second static pressure by a threshold amount.
