Abstract
A tank with an angled indicator assembly is disclosed. A flexible membrane may be connected to an inner wall of a shell of the tank and separates a tank cavity into a first chamber sealed to contain a pressurized gas and a second chamber sealed to contain a pressurized fluid. The tank may include an indicator assembly that includes a coupling connected to an exterior of the shell. A sight cap with a transparent viewing window can operably connect to coupling. The coupling and the sight cap define an internal viewing pocket in fluid communication with the first chamber of the tank cavity. The coupling may connect to the shell at an angle defined by the angle of a longitudinal axis of the coupling relative to a longitudinal axis of the tank.
Claims20
A tank comprising:
- a housing defining a cavity;
- a flexible membrane positioned within the cavity, the flexible membrane separating the cavity into a first chamber and a second chamber;
- and
- an indicator assembly coupled to the housing, the indicator assembly comprising:
- a coupling with a first end and a second end opposite the first end, the first end connected to an exterior of the housing at a coupling angle between a longitudinal axis of the coupling and a vertical axis of the tank, wherein the coupling angle is less than 90 degrees;
- and
- a sight cap coupled to the second end of the coupling and having a transparent viewing window, the sight cap and the coupling defining an internal viewing pocket that is in fluid communication with the first chamber of the cavity.
A tank comprising;
- a housing defining a cavity;
- a flexible membrane positioned within the cavity, the flexible membrane separating the cavity into a first chamber and a second chamber;
- and
- an indicator assembly coupled to the housing, the indicator assembly comprising an internal viewing pocket that is in fluid communication with the first chamber of the cavity,
- wherein the housing has a plurality of openings configured to provide the fluid communication between the first chamber of the cavity and the internal viewing pocket.
A tank comprising;
- a housing defining a cavity;
- a flexible membrane positioned within the cavity, the flexible membrane separating the cavity into a first chamber configured to contain a pressurized gas and a second chamber configured to contain a fluid;
- and
- an indicator assembly coupled to an exterior wall of the housing and extending from the exterior wall at a coupling angle between a longitudinal axis of the indicator assembly and a vertical axis of the tank, the indicator assembly comprising an internal viewing pocket that is in fluid communication with the first chamber of the cavity,
- wherein the coupling angle is less than 90 degrees, and
- wherein the housing has a plurality of openings configured to provide the fluid communication between the first chamber of the cavity and the internal viewing pocket, and the plurality of openings are configured to produce a turbulent flow of the fluid within the internal viewing pocket when a level of the fluid inside the first chamber exceeds a height of at least one opening of the plurality of openings.
