In a method for controlling the emptying cycle for a temporary storage space (5) at a deposit point (2, 3) of a pneumatic material collection and transport system where emptying of the storage space is performed by opening a discharge valve (10) provided downstream thereof, a storage space emptying state is detected during discharge valve open condition, the output from at least one storage space emptying state sensor (6, 7) is monitored and logged, the sensor output is evaluated, a discharge valve open time is computed based on monitored and evaluated sensor output and the discharge valve is closed when monitored and evaluated sensor output has indicated a storage space empty condition. An emptying cycle control assembly for performing such a method includes at least one storage space emptying state sensor (6, 7), means for evaluating the output from the sensor/sensors and means for computing a controlled valve open time based on monitored and evaluated sensor output to effect closing of the discharge valve when the monitored and evaluated sensor output has indicated a storage space empty condition. |
