One beam is reflected by the liquid surface falls on a line sensor, and the other beam falls on the line sensor without reflected by the liquid surface. When a housing and the liquid are relatively inclined, an incident position of one beam changes on the line sensor, whereas an incident position of the other beam does not change. An inclination angle to the liquid surface is determined based on the incident position of one beam with respect to the incident position of the other beam.
