摘要： A fluid level indicator (50) for indicating the fluid level in an ophthalmic irrigation and/or aspiration system comprises a chamber (10) configured for holding a surgical fluid (F). The chamber (10) comprises at least one fluid port (72; 74) and a pressure port (71) for connection to a pressure source (20). A channel (140) extends from the chamber (10). The fluid level indicator (50) comprises a float (160) having a float body (162) disposed within the chamber (10) and a stem (164) extending from the float body (160) into the channel (10). The float body (160) is configured to move with the level of fluid within the chamber (10), thereby moving the stem (164) along the channel (140) extending from the chamber (10). The position of the stem (164) within the channel (40) indicates the fluid level within the chamber (10).

摘要： A water level indicator having an upper housing, with a cavity, having a plurality of indicator flag caps disposed within the cavity, and a plurality of pushrods, wherein each indicator flag cap is connect to one of the plurality of pushrods, and each of the pushrods may have a different length. A plurality of floats, each having a locking hole, which receive and secures one of the plurality of pushrods. A first floats of the plurality of floats has a locking tab that secures the second end of a first pushrod, and the float having at least one through hole which allows a second pushrod of the plurality of pushrods to pass through the first float cage and the first float.

摘要： A level gauge for determining the level of a liquid in a vessel includes lenticular lens assembly allowing a plurality of level indicator flags enclosed therein to be viewed from a wide angle. The indicator flags have an elongated body manufactured from a sheet of material, and form a central pocket for retaining a magnet, and pins on either end for mounting within a frame. A mounting frame positions the lens assembly whereby an open channel is formed between the lens assembly and a back plate. The mounting frame is mounted to the vessel using spacers forming an open gap between the mounting frame and vessel. The open channel and gap minimize the transfer of heat from the vessel to the level gauge. The passage of a float with a magnet on the liquid in the vessel rotates the flags.

摘要： A liquid gauge mechanism of the type primarily designed to be used in containers utilized for maintaining or growing plants therein wherein the casing of the gauge mechanism is at least partially submerged within the root system and surrounding liquid so as to indicate the level of liquid within the container. An indicator element is movably disposed within the hollow container of the gauge mechanism and has indicia formed thereon so as to be viewable through the casing of the indicator means. The level of liquid within the container is the same as the level of liquid within the casing. The indicator element being floatable within the casing serves to position the indicia thereon in aligned relation with a window or viewing portion through the casing so as to indicate the level of the liquid relative to the root system of the plant maintained within the container.
