Title:
【発明の名称】流量測定装置
Document Type and Number:
Japanese Patent JPH0797041
Kind Code:
B2
Abstract:
Fluid delivery equipment, for example for distributing herbicide, is calibrated to provide a correct flow rate by performing a test cycle in which the fluid flows into a measuring device for a predetermined time, after which the volume of fluid in the measuring device is established to determine whether or not the flow rate corresponds to the desired flow rate. The measuring device establishes a flow path having two reverse bends (36, 30) with the reverse bend (36) bypassed by a vent hole (32). The level of liquid in the measuring device after a test is, for example, established by means of a graduated scale provided on a card (40) which is removably attached to a package containing the fluid to be distributed.
