Liquid mass measurement and fluid transmitting apparatus

A process for measuring a mass of liquid and transmitting fluid comprising:

• containing liquid in a container having an inlet and an outlet in fluid flow communication with said container to allow fluid to be transmitted from said container, said container, further comprising:
• a sensor, operatively engaged to said container, to produce one or more electrical signals proportional to a mass of liquid within said container independent of variations in pressure on said liquid, said sensor comprises a diaphragm oriented to sense changes in the mass of liquid within said container, wherein said fluid within said container is located over said diaphragm;
• an inlet in fluid flow communication with said container;
• an outlet in fluid flow communication with said container to allow fluid to be transmitted from said container;
• a controller electrically coupled to said sensor to receive and process said electrical signals;
• and
• a pressure equalizer to equalize the pressure on said liquid within the container with the pressure on a side of said diaphragm opposite said liquid, wherein said pressure equalizer comprises a conduit having a first end in fluid communication within said container and above said fluid within said container, and a second end in fluid communication with an area proximate a side of said diaphragm facing opposite said liquid within said container;
• producing one or more electrical signals proportional to a mass of the liquid within said container enabling said electrical signals to represent said mass independent of variations in pressure on said liquid using a sensor operatively engaged with said container;
• and
• receiving and processing said electrical signals using a controller electrically coupled to said sensor.

A liquid mass measurement and fluid transmitting apparatus comprising:

• a container configured to contain liquid for measurement of mass thereof;
• a sensor, operatively engaged to said container, to produce one or more electrical signals proportional to a mass of liquid within said container independent of variations in pressure on said liquid;
• an inlet in fluid flow communication with said container to allow fluid to be transmitted into said container;
• an outlet in fluid flow communication with said container to allow fluid to be transmitted from said container;
• at least one pressure control valve in fluid flow communication with said container to allow pressurized fluid to flow within and escape from said container;
• and
• a controller electrically coupled to said sensor to receive and process said electrical signals;
• wherein the inlet, the outlet, and the at least one pressure control valve are each positioned in a closed position to form a closed system.
