In many cases, the reasons canbe determined in this way and faults rectified.The below tables show typical examples of application-related meas-urement errors with liquids. The measurement errors are differentiatedaccording to the following:• Constant level• Filling• EmptyingThe images in column "Error pattern" show the real level as a brokenline and the level displayed by the sensor as a continuous line.12Leveltime01 Real level2 Level displayed by the sensorReaction when malfunc-tion occursProcedure for fault recti-ficationTreatment of measure-ment errors with liquids
