Liquid mass measurement and fluid transmitting apparatus

摘要

A liquid mass measurement and fluid transmitting apparatus includes a container for measurement of a mass of fluid therein. A sensor is coupled to the container which measures a mass of fluid within the container independent of variations of pressure within the container. A diaphragm sensor may be located on the bottom of the container whereby electrical signals representing the mass of fluid within the cylinder are created by movement of the diaphragm caused by the mass of fluid thereon. A pressure equalizer which equalizes the pressure within the container to the pressure on the opposite side of the diaphragm allows the measurement of the mass to occur independent of any variations and pressure within the container. Liquid within the mass of liquid within the container can be accurately measured such that a desired mass of liquid may be transmitted for further use. The liquid may be vaporized and transmitted as a vapor.

主权项

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:
a diaphragm oriented to sense changes in the mass of liquid within said container, wherein said diaphragm is positioned wherein liquid 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 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.
