About Flowmeters and Totalizers
Flowmeters measure the rate of flow for a liquid or a gas. Totalizers measure the cumulative flow volume. Flowmeter/totalizers display both the flow rate and the cumulative flow volume.

Easy-Read Flowmeters for Water
Instead of a scale, these flowmeters show flow rate readings on a prominent dial that’s easy to see from a distance. They measure the flow rate of water in your system and install directly in your pipeline.
For the most accurate readings, install these flowmeters a minimum distance of at least 10 times the pipe diameter from any fittings.
