ULTRASONIC AND PRESSURE COMPLEX LEVEL MEASURING TYPE FLOW METER FOR PARTIALLY FILLED PIPELINE

摘要

An ultrasonic and pressure complex level measuring flow meter for a partially filled pipeline is provided to measure the flow rate of a fluid regardless of the kind of the fluid by using both a pressure sensor and an ultrasonic lever measuring unit according to the level of the fluid. An ultrasonic and pressure complex level measuring flow meter for a partially filled pipeline includes a measuring pipe(100), a flow rate sensor(200), a pressure sensor(300), an ultrasonic level measuring unit, and a calculator. The flow rate sensor includes an exciting coil and a detection electrode. The pressure sensor is adjacent to the flow rate sensor and is installed at a lower end portion of the measuring pipe. The ultrasonic lever measuring unit is installed in the interior of a fixation pipe(420) of an upper end portion of the measuring pipe opposite to the flow rate sensor.
