<br /> Applications:Measurement of cold water where flow is in one
<br /> direction;in residential,commercial and Industrial services.

<br /> Conformance To Standards:Sensus Sealed Register Water
<br /> Meters comply with ANSI/AWWA Standard 0700,latest revision. .i
<br /> Each meter is tested to insure compliance ' i, -yppy
<br /> Construction:Sensus SR Water Meters consist of three basic

<br /> flanges or internally-threaded spuds.Measuring chambers are of
<br /> Rocksyna,a corrosion-resistant thermoplastic material.Bronze
<br /> measuring chambers are available as an option.
