Applications

The Challenger turbine meters are an ideal choice for the most challenging metering applications. These turbine meters are the defacto choice for consistent medium to high flow and immediate flow demand applications such as large-scale irrigation, high-rise building services and manufacturing. The Challenger is a compact, top-loading meter which can be adapted for almost any location, including vertical installations. While the Challenger meters do offer good low-flow capabilities, their primary application is for long-term performance and durability at high flowrates.

Operations

The Challenger meters utilize an innovative bearing design based on the proven Woltman turbine concept. A turbine is mounted on a shaft oriented parallel to the flow stream. The water forces the blades of the turbine to rotate the shaft in proportion to the velocity of the flow.

Due to the advanced bearing design, the meter maintains accuracy at almost any orientation, including vertical.

All Challenger turbine 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 tamperresistant housing.
