摘要：The flow rate of a fluid, such as a herbicide, from delivery equipment isestablished by causing the fluid to flow into a calibration vessel (14), and measuring thevolume which flows in a predetermined time. The vessel (14) is connected to a deliveryhead (8) of the equipment by an intermediate component (16). A tube (116) provides apassage for venting air from the vessel (14) as fluid flows into it. After a calibrationmeasurement, the fluid can be returned to the equipment by inverting the equipment.The outgoing fluid is then replaced by air flowing back through the tube (116).
