LIQUID LEVEL DETECTION SENSOR, LIQUID POURING DEVICE USING THE SENSOR, AUTOMATIC CAPACITY MEASUREMENT DEVICE FOR CONTAINER, AND LIQUID LEVEL DETECTION METHOD

摘要

Provided are a liquid level detection sensor capable of highly accurately detecting the height of the level of liquid in a container, a liquid pouring device using the sensor, automatic capacity measurement device for a container, and a liquid level detection method. A liquid level detection sensor having an upper electrode rod (2a) and a lower electrode rod (2b) that have different head heights and are appropriately horizontally spaced apart, wherein the upper electrode rod (2a) is formed such that, when the upper electrode rod (2a) and the lower electrode rod (2b) are inserted in a container (P), the head (2a') of the upper electrode rod (2a) is positioned close to the center line of the level of liquid in the container (P).
