Abstract
A no emission tank gauge has a housing having a valve connection extending from a bottom side of the housing, a gauge line within the housing, the gauge line having a plumb bob attached at a free end, a pulley attached within the housing and supporting the gauge line, the pulley configured to allow extension and retraction of the gauge line, and an actuator connected to the pulley and extending exterior to the housing and configured to actuate the extension and retraction of the gauge line via rotation of the pulley. The housing has a window in a wall of the housing facing a marked side of the gauge line. The valve connection has an opening sized to allow for passage of the plumb bob and the gauge line. The housing is sealed when the valve connection is connected to a valve to prevent escape of fluid.
Claims13
A no emission tank gauge system, comprising:
- a housing having a valve connection extending from a bottom side of the housing;
- a gauge line within the housing, the gauge line having a plumb bob attached at a free end;
- a pulley attached within the housing and supporting the gauge line, the pulley configured to allow extension and retraction of the gauge line;
- and
- an actuator connected to the pulley and extending exterior to the housing and configured to actuate the extension and retraction of the gauge line via rotation of the pulley, wherein:
- the housing has a window in a wall of the housing facing a marked side of the gauge line;
- the valve connection has an opening sized to allow for passage of the plumb bob and the gauge line;
- and
- the housing is sealed when the valve connection is connected to a valve to prevent escape of fluid.
A low emission tank gauge, comprising:
- a plug having a top surface;
- a slot formed in the top surface of the plug;
- and
- a gauge line extending through the slot and having a plumb bob attached at one end, wherein the slot is sized to just allow the gauge line to freely move through the slot.
A low emission tank gauge system, comprising:
- a storage tank;
- an isolation valve attached to a top of the storage tank and having a pipe nipple extending therefrom;
- a fitting on an end of the pipe nipple;
- and
- a low emission tank gauge, comprising:
- a plug having a top surface and an open bottom end, the open bottom end of the plug configured to mate with the fitting;
- a slot formed in the top surface of the plug;
- and
- a gauge line extending through the slot and having a plumb bob attached at one end, wherein the slot is sized to just allow the gauge line to freely move through the slot.
