Abstract
A chemical storage device and a method for monitoring chemical usage are described herein. The device and disclosed method utilize a chemical storage canister and a load cell integrated into one transportable unit. The load cell is capable of compensating for the added weight of attached dispensing devices used in the semiconductor industry. Additionally, the load cell continuously displays the weight of the chemicals as they are withdrawn from the chemical storage device. These functionalities are included in the control logic of the load cell which is incorporated into the load cell itself.
