The Electronic Part of the Metal Tube Rotameter

Abstract:

The electronic part of the metal tube rotameter which is based on the magnetic sensors and microcontroller C8051F005 is studied. The flow rate change causes the change of the floats position in the metal tube and leads to rotation of the coupling magnet. Then the change of magnetic angle is detected by the magnetoresistive sensors, and a signal is generated. The signal is processed by the electric circuit and made available for the microcontroller for sampling. Then it will has linearization fitting in the microcontroller and finally has a output. This system could automatically sample the flow signal, calculate the instantaneous flow rate, and display them on the LCD screen.
