Abstract:
1. 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, said sensor comprising: 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 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 at a location above said liquid 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.
