Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If equipped with speed-indicating or recording features
Anemometers with integrated speedometers or data loggers may classify under revolution counters and speed indicators
If for industrial machinery parts use exclusively
Parts suitable solely for specific machines under chapter exclusions go to machine headings, not general measuring instruments
If other measuring instruments without flow-specific function
If not primarily for flow/level/pressure variables, it falls into other optical/measuring instruments
