Publication number: 20230392976Abstract: A fluid container measurement system is configured to suspend a load measurement assembly a distance above a support surface. The load measurement assembly houses a load cell and a measurement control circuit. The measurement control circuit is coupled to the load cell and configured to receive electrical signals indicative of a force imposed on the load cell. Electrical signals generated by the load cell indicative of the force exerted on the load cell can be used to measure the fluid container attached to the load cell linkage member. Methods of measuring a fluid container include attaching a fluid container to a fluid container attachment region and displaying the load measurement on a display adjustably attached to an upper surface of the housing of the load measurement assembly.Type: ApplicationFiled: August 16, 2023Publication date: December 7, 2023Inventors: Walter D. Parker, Edward J. Mueller, Keith H. Gausmann, Nathan T. Luck, Scott E. Liddle
