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.

Any-Orientation Flowmeters
A spring piston instead of a float allows these flowmeters to measure flow rate in any mounting orientation. As liquid passes through, it pushes an indicator up the scale, showing you the flow rate. They have union fittings on both ends, making it easy to position the scale so it’s visible.
These flowmeters are calibrated with 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.
Choose a fitting material that is compatible with the liquid you intend to run through your line. Polysulfone fittings work with a wide range of chemicals. However, they can crack from impact or when overtightened.
