Method and device for detecting average liquid level in a bottle |
摘要 |
A method for detecting a liquid level is monitored at mutually opposing sides of a liquid containing bottle. For monitoring the liquid level at each side of the bottle, a diffused light beam is irradiated toward the liquid surface from a level below the liquid surface. The light reflected at the liquid surface and the light refracted at the liquid surface are detected by a photo-receiving camera which is focused at a standard liquid level. An average value of the monitored liquid levels at both sides is taken as a liquid level indicative value. By employing the aforemention method, accurate detection of the liquid level becomes possible even when the liquid level is unstable.
