Abstract
An apparatus is provided for measuring level of a process fluid in a container opening. The apparatus includes a remote seal configured to be inserted into the container through an opening and configured to receive a pressure related to the level of process fluid in the container. A capillary tube filled with a fill fluid extends from the remote seal to the opening and is configured to convey the pressure therebetween. A pressure sensor coupled to the capillary tube senses the pressure from the capillary tube and responsively determines the level of the process fluid in the container. The remote seal includes a bellows portion arranged to isolate the process fluid from the fill fluid in the capillary tube and convey the pressure therebetween.
