Abstract: A system for measuring a fluid level using an acoustic impedance matching is disclosed, which is capable of accurately measuring a fluid level using a flat panel medium, in particular, polyethylene, with the flat panel medium being impedance-matched with an object medium. The flat panel medium having the same acoustic impedance as the object medium is used, and the limit switch is directly connected through the flat panel medium, so that the angle coincidence problems are resolved. Since the sizes of signals are high, the construction of the electronic circuit is simplified, and the fabrication process is easy. The price of the system is low. Since polyethylene is used as the flat panel medium, the impedance matching with the object medium is easily achieved. Therefore, the present invention may be well adapted to measuring the fluid level.
