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.

High-Temperature and Pressure Flowmeters for Oil
If the oil in your line is too hot or pressurized for standard flowmeters, use these flowmeters to measure the flow rate. As oil flows through, it pushes an indicator up the scale, showing you the flow rate. The scale rotates 360°, so you can check the flow rate from any angle. These flowmeters measure flow correctly in any mounting orientation. Install them inline with your pipe system.
These flowmeters are calibrated with oil but can be used with other liquids. If you’re using these with a liquid other than oil, 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 oil you're running through your line.
