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.

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.
