摘要：Fluid delivery equipment, for example for distributing herbicide, is calibrated toprovide a correct flow rate by performing a test cycle in which the fluid flows into ameasuring device for a predetermined time, after which the volume of fluid in themeasuring device is established to determine whether or not the flow rate correspondsto the desired flow rate. The measuring device establishes a flow path having two reversebends (36, 30) with the reverse bend (36) bypassed by a vent hole (32). The level of liquidin the measuring device after a test is, for example, established by means of a graduatedscale provided on a card (40) which is removably attached to a package containing thefluid to be distributed.
