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.

Flowmeters with Flow Switch
Monitor the flow rate of liquids and use the integrated switch to turn equipment on and off, or activate an alarm when liquid reaches a set flow rate. The switch is single pole, double throw (SPDT) and can be installed to turn one circuit from off to on (normally open) or on to off (normally closed). As liquid flows through these flowmeters it pushes an indicator up the scale, showing you the flow rate. Mount them inline with your pipe system. They will measure flow correctly no matter which orientation you mount them in. Rated NEMA 13, they protect against dust, spraying oil, and damp environments.
These flowmeters are calibrated using water but can be used with other liquids. If you’re using these with a liquid other than water, you’ll need to calculate the flow rate by multiplying the number shown on the scale by the specific-gravity conversion factor for your liquid.
