Abstract
A system and method for detecting and displaying the amount of chemical in a vessel. The system includes a vessel with a variable quantity of gas supported upon a moveable platform. A hydraulic load cell is positioned under the platform, and generates a hydraulic pressure signal, which is a function of the variable quantity of gas in the vessel. An electrical signal transducer converts the pressure signal to an electrical signal which is transmitted to a battery powered microprocessor/display capable of converting the electrical signal into a displayable signal indicative of an amount of gas remaining in the vessel.
