Abstract
A medical/surgical waste collection rover includes a first waste container disposed on a portable cart and receiving waste under the influence of a vacuum. A fluid measuring system includes a float element disposed within the first waste container, and a controller causing liquid in a reservoir disposed on the cart to prefill the first waste container and subject the float element to an initial lifting to a zero point level. The fluid measuring system determines a volume of contents within the first waste container based on a position of the float element relative to the zero point level. The fluid measuring system may include a sensor rod extending through the first waste container and a second waste container disposed on the cart and separated from the first waste container by a transfer valve. Methods of estimating the volume of liquid and/or medical/surgical waste within the waste container are also provided.
