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.

Bottom Connection

Clearly read pressure levels in your drinking water system, even with heavy vibration. The dial face is filled with glycerin, which absorbs shock and keeps the needle steady. These gauges meet NSF/ANSI 61 for drinking water. Mount them with the dial face upright.

Check the pressure on your drinking water system with these gauges—they meet NSF/ANSI Standard 61 for safe use with potable water. The dry dial on these gauges is best for low-vibration applications, since the needle can bounce if the gauge is shaken. For more accurate readings under heavy vibration, use a liquid-filled gauge. Mount gauges with the dial face upright.
