PURPOSE:To make the confirmation of the liquid level easy by recessing the bottom face of the window shaped base body consisting of a transparent mterial and by forming a foaming chamber. CONSTITUTION:A foaming type liquid meter 1 is made by forming a foaming chamber 2 with bending upward the lower face of the base body A of window shape consisting of a transparent material, and the cylinder 14 fitted to the tip of the liquid meter 1 is inserted into a container 10 from the pouring port 13 of the upper face thereof. When the chamber 2 is brought into contact with the liquid 5, then the air being shut in the chamber 2 is made a bubble 4 and a visual annularity 2 appears on the periphery thereof due to surface tension and the observation is made easy. |
