Product Description
A significant advantage of the module is its powerful one- Watt transmitter. The long range enabled by the
strong signal and high receiver sensitivity, minimizes the number of base station receivers an d provides
optimal coverage at minimal deployment and ongoing costs. FlexNet transmitters are powered by a
replaceable Lithium battery pack, with an expected service life of over 20 years.
The transmitter is enclosed in a durable polycarbonate casing with a clear cover that enables reusing the
original meter index. The module consists of a narrow band transmitter, magnetic sensors, and mechanical
meter interface that includes a shaft with a magnet. A handheld terminal is used to initialize operation. The
module monitors the meter and sends data to the base station receiver network at predefined and
programmable intervals. Transmitter messages contain meter reading data, status and relevan t parameters
such as index pressure and the number of dials. Messages are routed to a database, where the data gets
formatted for export to billing, marketing and customer service systems.
The FlexNet® wireless transmitter for gas AMR
applications permits offsite meter reading by way of a
fixed base radio network. In addition to solving meter
reading problems such as lockouts, entering unsafe
meter locations, "curbside" reading estimates,
estimated billing, and errors associated with manual
meter reading methods, a fixed network provides
benefits such as daily reads and status alerts.
