Applications

The Spectrum Single-Jet Meter is the widest range, single measuring element meter available to U.S. utilities. The Spectrum residential meters are designed for extremely wide range and long-term accuracy.  The single-jet technology is highly impervious to dirt, sand or grit in the water system.  The combination of design simplicity, superior grade materials, and high quality manufacturing standards allows for years of virtually new meter performance with no maintenance.

The Spectrum residential meters are available in  composite (reinforced plastic) and lead-free bronze models across all common residential sizes. 

Coupled with the advanced innov8 registers, the Spectrum single-jets are the meter of choice for your revenue assurance and water loss programs.

Operations

Incoming water rotates a suspended impeller that is magnetically linked to the register.  A low friction tungsten carbide bearing supports the impeller at low flow rates while a tungsten carbide thrust bearing provides the support at high flow rates.  This unique “dual bearing” design provides unparalleled accuracy and durability at both high and low flows.

To maintain accuracy, the meter must be installed horizontally (±10°) in the direction of water flow. 

All Spectrum Model D meters utilize innov8 registers.  These sealed electronic registers provide a high resolution interface to the meter and have multiple cellular, AMR, AMI and SCADA outputs.  All registers are attached with a robust tamper-resistant housing.

Design Features

  • High accuracy – exceeding high and low range of AWWA residential standards
  • Starting flow below 1/16 gpm
  • Excellent performance in adverse water conditions
  • Advanced materials for long-term durability
  • Unaffected by sand or small debris in line
  • No straight pipe requirements upstream or
  • downstream of meter
  • High resistance to freezing
  • Lightweight, compact design for simple installations
  • No strainer requirement
  • Compatible with all innov8 registers and associated AMR/AMI capabilities.

Materials

All residential Spectrum Model-D meters are designed and manufactured to meet or exceed AWWA C712 standard design and performance specifications.  All Models are maintained with NSF-61G lead-free certifications.
