System and method for determining fluid level in a container |
摘要 |
Methods and systems employing acoustic techniques are disclosed for determining the level of fluid in a container. Flexural mode acoustic waves are set up in the walls of the container. The change in travel time of flexural mode acoustic waves are measured and calibrated in terms of the level of fluid in the container. Systems for continuously monitoring fluid level or indicating when fluid level reaches a predetermined horizontal level are disclosed.
