Spectrum Single-Jets
Applications
The Spectrum Single-Jet Meter is the widest ranged, single-measuring element meter available to U.S. utilities. The operation of the single jet element allows the meter to be applied in the vast majority of potable cold water, small commercial applications. These meters are designed with a very high range, including low flow performance equaling or exceeded all other metering technologies. Coupled with the advanced innov8 registers, the Spectrum single-jets are the meter of choice for your revenue assurance and water loss programs.
All Spectrum Model-D meters are top-loading, chamber designs which allow for field maintenance and repairs.
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. The Spectrum 88DL and 88 DLT come with an integral test port on the outlet. Although regular maintenance is not required, the Spectrum Model D meters have a top-loading measurement chamber for simple access without removing the meter from service. The chamber is bolted to the meter body and secured with a tamper seal.
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.

Enduro Fire Service Meter
Applications
The Enduro water meters are single element, wide range industrial meters. The Enduro Model-D meters utilize a top-loading chamber to insert a small diameter Spectrum meter within the flow stream. This unique system allows for unparalleled accuracy and durability at both high and low flows within a compact meter body. The Enduro meters are an ideal solution for most industrial metering applications.
Fitting the Voyager with an innov8-VN register conveniently provides remote cellular-based readings via Metron’s Waterscope System. This allows the utility to track reads and consumption during the meter’s field time. An optional GPS unit also allows the utility to track the location of the meter on Google™ Maps.
Operations
Water enters the meter passing over an in-line water conditioner that directs the water through a small diameter Spectrum meter that proportionally measures the total water flow. This incoming water rotates a suspended impeller in the measuring chamber. A low friction pivot bearing supports the impeller at low flow rates while an upper thrust bearing provides the support at high flow rates. The impeller has an attached magnet at its top for the register interface.
All bearing materials are fortified for minimal wear during high-flow stress. The impeller shaft utilizes tungsten tips to minimize wear and ensure long-term accuracy. The Enduro Model-D meters come with integral flanges (either 6” or 8”).
To maintain accuracy, the meter must be installed horizontally (±10°) in the direction of water flow. Enduro meters come with an integral test port on the outlet. Although regular maintenance is not required, the Enduro meters have a top-loading measurement chamber for simple access without removing the meter from service.
All Enduro meters utilize innov8 registers. These sealed electronic registers provide a high resolution interface to the meter and have multiple output options. All registers are attached with a robust tamper-resistant housing.
