Abstract
An apparatus and method for measuring a liquid level in a vessel using an acoustic wave. Acoustic tubes have first ends disposed vertically along a sidewall of the vessel for each of the liquid levels to be measured, and the tubes communicate with the inside of the vessel. Second ends of the tubes are connected to a common tube. A storage level sensor board generates the acoustic wave in the vessel, receives the acoustic wave propagated through the acoustic tubes and the common tube, and determines the level of liquid in the vessel based on the received acoustic wave.
Claims13
An apparatus for measuring a liquid level comprising:
- a vessel for receiving a liquid;
- a plurality of acoustic tubes having first ends disposed vertically along a sidewall of the vessel for each liquid level to be measured and communicating with the inside of the vessel, and second ends communicating with a common tube;
- and a storage level sensor board that generates an acoustic wave in the vessel, receives an acoustic wave propagated through one or more of said acoustic tubes and said common tube, and determines the level of the liquid in said vessel based on the received acoustic wave.
A method of measuring a liquid level, comprising:
- generating an acoustic wave in a vessel for containing a liquid;
- arranging a plurality of acoustic tubes so as to be disposed vertically along a sidewall of the vessel, and receiving an acoustic wave propagated through one or more of the acoustic tubes which are not submerged in the liquid;
- and
- outputting the received acoustic wave as an electrical signal, comparing the output electrical signal with tabulated data and evaluating a liquid level.
