| PURPOSE: To provide a liquid level meter which can be manufactured at a low cost, and by which the liquid level even in a colorless liquid can be simply discriminated. CONSTITUTION: A liquid level meter for a metallic bowl 1 used in a compressed air filter or an oil feeder comprises light colored rear walls 4, 5, a transparent front window 12 and a front wall where plural small triangular cones are formed. When the triangular cone 14 comes into contact with the air, most of incident light is reflected, but most of light coming into contact with the liquid is transmitted through a sealing small piece 5. Thus, a light colored image corresponding to the liquid level in the bowl 1 and a colorless image are shown in contrast from the front window 12 so that the liquid level in the bowl 1 can be easily observed. | ||||||

| PURPOSE: To sense the level of ink in an ink cartridge by fitting in a part above a print head to be connected with a capillary ink reservoir. CONSTITUTION: In a full-foam pen, an ink level sensor 18 provided on one surface (side) a housing 12 is filled with ink and is in a static equilibrium state. Namely, although a liquid surface 1 (interface of ink/air in foam) is positioned above an upper port 20a, when the ink surface L reaches the upper port 20a, due to the imbalance between the capillary pressure at the ink/air interface of the foam and the capillary pressure in the upper port of the sensor 18, ink is sucked from the sensor 18 into the foam. As a result, the ink in the sensor 18 is reduced abruptly, and the function of a binary fluidic indicator is exhibited. In this way, since a tube 20 is transparent, the change from a full state to an empty state can be found immediately by both a user and the mechanical sensor. COPYRIGHT: (C)1991,JPO | ||||||

| PURPOSE:To enable the obvious display of a position of a liquid level, by applying rays of light, from a position lower than the liquid level, to a standing-up portion of the liquid level formed by the surface tension of the liquid, and by receiving the rays reflected by said standing-up portion by means of a light- receiving camera. CONSTITUTION:On the occasion of the control of a quantity of a liquid 11 filled in a bottle 10, a light source assembly 12 is disposed on one side of the bottle 10 and a light-receiving camera 13 on the other. The light source assembly 12 comprising a light source 14 and a diffusion plate 15 is set so that rays 16 of light emitted therefrom are applied, from a position lower than a liquid level 17 in the bottle 10, to a rise portion (standing-up portion) 18 of the liquid level on the light-receiving camera side which is formed by the surface tension of the liquid. The rays of light applied to said portion are reflected by the circular-arc part 18a of the rise portion, transmitted through the wall of the bottle 10 and received by the light-receiving camera 13. The rays are converted thereby into a voltage and displayed at a bright stripe-shaped portion 21 indicating the position of the liquid level 17 by a display means. | ||||||
