Abstract
Official abstract text for this publication.
A method includes initiating a test of a servo gauge by causing the servo gauge to attempt to move a displacer of the servo gauge, where the servo gauge uses a drum to move the displacer in a tank. The method also includes measuring a torque associated with the drum during or after the attempt to move the displacer and identifying a mechanical problem with the servo gauge based on the measured torque. For example, a stuck displacer can be identified when the measured torque exceeds an upper expected value. A lost displacer or a stuck drum can be identified when the measured torque is below a lower expected value.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: identifying, over a period of time, a change that is less than a threshold amount to a level of a displacer of a servo gauge in a tank; responsive to identifying the change that is less than the threshold amount and based on whether a measured level of material in the tank has remained constant or substantially constant for a specified period of time, automatically initiating a test of the servo gauge by causing the servo gauge to atte…
