Abstract
Systems and methods of diagnosing performance of a level sensor of a fluid test chamber, including a data acquisition and processing unit configured to receive output signals of one or more level sensors that are installed to a fluid chamber, the data acquisition and processing unit being configured to connect to the one or more level sensors to record and process the output signals to test operation of the one or more level sensors.
Claims12
A system for diagnosing performance of a level sensor of a fluid test chamber, comprising:
- a data acquisition and processing unit configured to receive, record, and process the output signals of one or more level sensors that are installed to a fluid chamber.
A method for in-situ calibration verification of one or more level sensors installable within a sealable test chamber, the test chamber comprising at least one upper penetration and at least one lower penetration, the method comprising:
- connecting a calibrated reference sensor such as a differential pressure sensor or sight gauge to the test chamber via the at least one upper penetration and the at least one lower penetration;
- filling the chamber fluid level to one or more predetermined levels of fluid;
- recording output signals of the one or more level sensors and the calibrated reference sensor;
- and
- comparing the outputs signals to baseline data to quantity drift.
