Open the CIPO recordAbstract From the Canadian patent
The flow rate of a fluid, such as a herbicide from delivery equipment is established by causing the fluid to flow into a calibration vessel (14) and, measuring the volume which flows in a predetermined time. The vessel (14) is connected to a delivery head (8) of the equipment by an intermediate component (16). A tube (54) provides a passage for venting air from the vessel (14) as fluid flows into it. After a calibration measurement, 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 (54).
