Functional Description
The Interpreter is a wireless battery endpoint for the application of automatic water meter
reading. The primary function of the module is to record magnetic field reversals that are
converted to measurement of water consumption volume, and then deliver the data to the
utility for processing. The block diagram below demonstrates this operation.
Figure 2. Operation Block Diagram
The module is designed to record consumption of a water meter from an encoded register.
The count from the action of the meter advances the register and passed serially to the
radio.
The radio has two operating modes, frequency hopping and single channel. The frequency
hopping mode is the normal operating mode for network communication. The single
channel mode is a low power mode and is primarily used for field diagnostic purposes.
When installed, the module automatically utilizes the FHSS mode to operate as part of a
mesh network. The module will remain in this mode unless a service event is initiated from
the field tool. In this case the radio changes to the single channel mode for the duration of
the service session. The module returns to the FHSS mode when the service session is
closed. The user does not have the ability to change modes other than using the field tool.
