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 Panel-Mount Flowmeters
Flowmeter
Flowmeter with Flow-Control Knob
Install these flowmeters in an instrument panel to measure the flow rate of hot water and other liquids reaching up to 212° F. They should be mounted vertically, so liquid flows up from the bottom. As liquid flows through, it pushes an indicator up the scale, showing you the flow rate.
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.
Flowmeters with a flow-control knob let you open and close the inlet valve to adjust the flow rate within the range.
