The Sensus S275 is a Class 250 residential diaphragm meter that combines the latest design concepts with modern engineering materials. Lighter weight and easy to use, they are more durable, require less maintenance, and offer greater life expectancy than other meters in its class. It has a temperature compensation element that has increased strength in order to minimize deflection from valve drag. It has a simplified crank bracket, which provides accurate positioning of the crank support. Its low-friction polymer material eliminates also the need for lubrication. Close tolerances and molded phenolic construction of the valve seat provide smoother operation and minimize wear.
