Sealed Register" Water Meters DISPLACEMENT TYPE MAGNETIC DRIVE Je SvJS COLD WATER METERS 11/2" (DN 40mm) AND 2" (DN 50mm) SIZES DESCRIPTION SPECIFICATIONS APPLICATIONS: Measurement of cold water where flow is only in one direction;in residential,commercial and industrial services. CONFORMANCE TO STANDARDS: Sensus Sealed Register' Water v �+ Meters comply with ANSIIAWWA Standard C700, latest revision. Each 1 meter is performance tested to insure compliance. CONSTRUCTION: Sensus SRT Water Meters consist of three basic components:maincase; measuring chamber;permanently,hermetically- sealed register. Maincases are of bronze with either flanges or internally-threaded spuds. Measuring chambers are of Rocksyn;^ a corrosion-resistant thermoplastic material.Bronze measuring chambers are available as an option. i14"SR' 2"SR` SEALED REGISTER': Permanently, hermetically sealed; proven ION 40mm) IDN 50mm) magnetic drive design; with integral tamper-proof locking device.
