Where can I get the measurement units of the sensor data? I'm working with the time series data for anomaly detections models and I would like to know the units of the sensor data. I found a master thesis based on the Open Industrial Data and for the variables selected for it; the author specifies the units: But from the data I downloaded with the SDK the tag VAL_23_KA_9101_M01_62C:Z.X.Value does not have unit: I looked into the meta data field an the engunits key is empty:{'P&ID No': None, 'PLC': None, 'PLC tagname': None, 'Sensor type': None, 'Tag group': None, 'Tag type': None, '_replicatedInternalId': '4326942079596138', '_replicatedSource': 'akerbp', '_replicatedTime': '1593024714000', 'archiving': '1', 'compdev': '0', 'compdevpercent': '0', 'compmax': '28800', 'compmin': '0', 'compressing': '1', 'convers': '1', 'descriptor': 'PH 1stStg Comp Mtr Current', 'digitalset': '', 'displaydigits': '-5', 'engunits': '', 'excdev': '0', 'excdevpercent': '0', 'excmax': '600', 'excmin': '0', 'exdesc': '', 'external id': None, 'filtercode':
