PURPOSE: Device and method for manufacturing the flow rate of a complex partly-filled-pipe are provided to enable easy installation of an electronic flow-meter and one water level sensor to simultaneously measure flow rate in a PB flume way and in an electronic way. CONSTITUTION: A device for manufacturing the flow rate of a complex partly-filled-pipe comprises a PB flume(10), a pair of water level sensors(20), a flow-speed sensor(22), and a control unit(30). The PB flume consists of an inlet unit, a straw unit(14), and an outlet unit, starting from where fluid flows. The water level sensors are installed on the bottom of the inlet unit. The flow-speed sensor is installed on the crest unit of the straw unit. The control unit receives a detecting signal from the water level sensor and the flow-speed sensor and measures flow rate. Signals related to water levels are input from the water level sensors.
