Claim Text:
1. A magnetic field sensor, comprising: a head comprising a first sensor, a second sensor, and a third sensor, wherein the first sensor is oriented to measure a magnetic field generated by a water meter along a first axis, wherein the second sensor is oriented to measure the magnetic field along a second axis different from the first axis, wherein the third sensor is oriented to measure the magnetic field along a third axis different from the first axis and the second axis, and wherein the head is positioned a first distance from the water meter; a cable comprising a first end and a second end, wherein the first end of the cable is coupled with the head, wherein the cable is configured to receive a first measurement measured by the first sensor, a second measurement measured by the second sensor, and a third measurement measured by the third sensor, and wherein the cable is further configured to transport the first measurement, the second measurement, and the third measurement to the second end of the cable; and a transceiver coupled to the second end of the cable, wherein the transceiver is configured to wirelessly transmit the first measurement, the second measurement, and the third measurement received from the second end of the cable to a remote server over a network.
