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 float activated gauge for indicating the level of liquid in a tank utilizes a twisted float following member. The float following member is disposed adjacent to the float and is caused to rotate as the float moves vertically due to a change of the level of liquid in the tank. A U-shaped main body for the gauge guides the float vertically, holding the float captive and against the float following member. A needle extends at a right angle from the float following member and is externally visible to provide an indication of the amount of rotation of the float following member and, therefore, the level of liquid in the tank.

摘要： A liquid level indicator for a liquid container, such as the crankcase oil reservoir of an internal combustion engine, comprises a source of fluid at a predetermined pressure and a fluid conduit system connected to the fluid source. A gage responsive to fluid pressure and a valve mechanism are coupled to the conduit system downstream of a restriction orifice in the system. The valve mechanism includes an outlet orifice for fluid in the system and a valve body that is movable axially of the orifice so as to vary its cross-sectional flow area. The valve body is coupled to a float that is mounted for limited vertical movement in the container so that when the liquid in the container is at any particular level within a predetermined range, the liquid exerts a buoyancy force on the float which is balanced by opposing forces, including the float weight and a force exerted by the pressurized fluid on the float through the valve body. The force exerted by the fluid is reflected in a corresponding fluid pressure in the conduit system between the restriction orifice and the outlet orifice. This pressure is a measure of the liquid level in the container.
