• AWWA Standard - Meets or exceeds all sections of Standard ANSI / AWWA C708, most
recent revision for cold water multi-jet meters with AWWA bronze main cases.
• NSF/ANSI Standard 61 -Optional EnviroBrass unleaded main case available.
• Design/Operation - Velocity - type flow measurement. Water that is evenly distributed by
multiple converging inlet ports flows past an impeller in the measuring chamber, creating
an impeller velocity directly proportional to water flow rate. The meter’s register integrates
that velocity into totalized flow. An inherent advantage for this design is exceptionally
low head loss for improved infrastructure efficiencies and unparalleled wear mitigation.
The register assembly is removable under line pressure permitting seamless, simplified
upgrades in reading technology.
• Main Case - Choice of waterworks bronze case of 81% copper composition or EnviroBrass®
II, 86% copper, unleaded bronze. Main case incorporates either compact externally
threaded ends, or bolted flanged connections.
• Measuring Chamber - The measuring chamber housing and measurement element are
built with an advanced synthetic polymer. This tough, non-hydrolyzing material ensures
durable wear. The chamber design optimizes water flow, eliminating harsh turbulence for
smooth, easy, operation that minimizes bearing wear. Measurement surfaces are not wear surfaces, providing sustained accuracy despite the
presence of entrained solids in the water. A long-life, synthetic sapphire bearing serves as
a wear surface. The chamber housing is constructed in two parts to allow access to the
impeller.
• Magnetic Drive - A reliable, direct magnetic drive provides linkage between measurement
element and register. No intermediate gearing is required; no gearing is exposed to water.
• Register - Standard Direct Read, DIALOG 2G and DIALOG 3G AMR System registers are
available. Six wheel odometers are standard. Together, an integrated and migratable technology environment is attained; direct, proximity (wand), mobile AMR, and Fixed Network AMI.
• Register Sealing - All Direct read and DIALOG® registers are IP-68 rated, permanently
sealed with a scratch resistant glass lens, stainless steel base and wrap-around gasket to
prevent intrusion of dirt or moisture.
• Register Units - Registration available in either U.S. gallons, cubic feet or cubic
meters.
• Test Circle - Large center sweep hand with one hundred (100) clearly marked gradations
on the periphery of the dial face.
• Magnetic Drive - A reliable, direct magnetic drive provides linkage between measuring
element and register so that no gearing is exposed to water.
• Test Circle - Large center sweep hand with one hundred (100) clearly marked gradations
near the periphery of the dial face.
• Low Flow/Leak Indicator -Clearly visible leak indicator with high sensitivity resulting
from direct one-to-one linkage to the measuring element.
• Strainer -A rugged, 360-degree polymer basket strainer protects the critical measuring
element from damage.
• Adjusting Port Detection -The Master Meter Multi-jet adjusting port is sealed after
factory calibration to prevent tampering and provides a visual indication of tampering
attempts. Port is accessible for utility recalibration to compensate for inaccuracy in older
meters without parts replacement.
