Abstract:
1. A cleaning quality control system using an electromagnetic flow meter, comprising: an electromagnetic flow meter to flow detergent drain of not less than a definite amount whose flow rate is measurable and to measure the flow rate of the detergent drain; and a cleaning quality control device to automatically determine cleaning quality as to whether or not cleaning has been completed from a detection signal of the electromagnetic flow meter; the cleaning quality control device including, an S/N ratio measuring unit to measure an S/N ratio of the detection signal of the electromagnetic flow meter, and a cleaning completion determining unit which is provided with an S/N ratio•electric conductivity determining table in which outputs of the S/N ratio measuring unit and respective electric conductivities of detergent drains are previously made correspondent using the detergent drains with predetermined electric conductivities, and which outputs cleaning completion when an obtained electric conductivity thereof becomes not more than a predetermined electric conductivity; and obtains the electric conductivity of the detergent drain from a value of the S/N ratio of the electromagnetic flow meter, and thereby automatically determines the cleaning quality as to whether or not cleaning has been completed.
