R-275 Diaphragm Meters


Residential Gas Meters Under 500 Cubic Feet per Hour

The R-275 are Class 250 residential diaphragm gas meters that combine the latest design concepts and modern engineering materials. Lighter weight and easy to handle, they are more durable, require less maintenance and offer greater life expectancy than previous meters in this class.

The temperature compensation element has increased strength to minimize deflection from valve drag. A simplified crank bracket provides accurate positioning of the crank support, and its low-friction polymer material eliminates the need for lubrication. Close tolerances and molded phenolic construction of the valve seat provide smoother operation and minimize wear. The R-275 meters also accommodate external valve guides, which are easily installed in these meters.

Our revolutionary, patented accuWAVE diaphragm is now standard on R-275 meters. This design has a longer life expectancy, improved long-term performance—even in extreme conditions—exceptional proof stability and a lower overall lifetime cost.

Dig Safely!
Sensus is committed to the safe use of natural gas. That’s why we’ve partnered with the Common Ground Alliance to mark all gas meters sold in the United States with a “Call 811 Before You Dig” decal. It’s a simple way to educate and remind homeowners to make sure underground lines are marked before digging—to avoid damage or injury.
