Patent ID: 8656752

Claim:
A method for adjusting a flow meter, comprising the steps of: providing a flow meter having a body portion attached to a pipe wherein a fluid to be measured flows, the body portion having a main flow path wherein the fluid to be measured flows, and a branch flow path branching the flow of the fluid to be measured from the main flow path and being provided with a hole portion having an opening diameter that relaxes a flow speed of the fluid, and a fluid measuring portion, attached detachably to the body portion by screwing a screw into a screw hole provided on an outer surface of the body portion, that measures the flow rate of the fluid to be measured, flowing in the main flow path, based on a detection result for the fluid to be measured that has been introduced from the branch flow path; attaching the fluid measuring portion to the body portion; recording in the fluid measuring portion flow rate adjustment data corresponding to the body portion described in identifying information provided on the body portion; and adjusting the measurement process based on the flow rate adjustment information that has been recorded.
