Title: Liquid level detecting apparatus
Inventor: IKEDA ATSUSHI
IPC: G01F23/24
Filed: 1999-09-28
Abstract: PROBLEM TO BE SOLVED: To surely and accurately detect a liquid level in a dissolution tank without being affected by a high-humidity environment in the dissolution tank, waving of the liquid level, bubbling when a liquid is dissolved, or the like.
