Flow Meters without Electrical Function

For applications where local flow indication is sufficient, non-electrical flow meters provide a simple way to monitor liquid or gas movement without auxiliary power. Using purely mechanical or visual operating principles, they help you assess process conditions directly on site and support robust flow checking in industrial systems, supply lines, and service environments.
