A magnetic shield may be mounted to a water meter housing to protect the magnetic operation of the water meter from a tamper magnet, including both smaller, flexible tamper magnets and larger, strong tamper magnets. The shield may include a contoured portion and a barrier portion. The barrier portion may provide a physical and spatial barrier between a larger tamper magnet and an internal magnetic sensor of the water meter. The contoured portion may conform to the housing of the water meter and may prevent smaller tamper magnets from being maneuvered close to the housing of the water meter. The shield may be made of a ferrous material suitable for attenuating a magnetic field. The shield may receive a looped sensor transmission cable within a U-shaped opening enabling the shield to be installed and/or removed from the water meter without the sensor transmission cable being detached from the water meter.
