SmartPoint® 520M Pit Set Module


The SmartPoint® 520M pit set module is a radio transceiver designed for use in submersible, pit set environments. With true two-way communication ability, it serves as a walk-by end point, drive-by end point, fixed-base end point or any combination of those. This versatility gives you highly flexible data collection options and simplifies both current operations and network evolution.

The 520M collects data from the meter register and transmits it to the collection device. In walk-by/drive-by mode, the transceiver collects data and waits for an activation signal from the Vehicle Gateway base station (VGB) or handheld device (HHD). When it receives a signal, it transmits the readings, the meter identification number and any alarms. As a fixed-base end point, the 520M interacts with strategically placed base stations in the service area. Utilities can migrate from walk by/drive-by to fixed-base by simply adding a base station.
