Abstract
A system includes an optical pressure sensor. A controller is operatively connected to receive input from the optical pressure sensor. An output connection is operatively connected to communicate output data from the controller. The controller includes machine readable instructions configured to cause the controller to receive data from an optical pressure sensor, detect an accumulation of contaminant on the optical pressure sensor, and initiate a corrective action through the output connection in response to detecting the accumulation of contaminant.
Claims16
A method comprising:
- receiving data from an optical pressure sensor;
- detecting an accumulation of contaminant on the optical pressure sensor;
- and
- initiating a corrective action in response to detecting the accumulation of contaminant, wherein initiating corrective action includes determining liquid level and/or liquid quantity in a container without using data from the optical pressure sensor, wherein determining liquid level and/or liquid quantity in the container without using data from the optical pressure sensor includes using data from one or more non-contaminated sensors at a different depth or depths in the container from the optical pressure sensor.
