TVM™ Voltage Monitor
Brand: Sensus, a Xylem BrandThe Honeywell A3 ALPHA Meter brings advanced metering capabilities to commercial and industrial applications.
The Sensus FlexNet Communication Network SmartPoint module is integrated into the A3 ALPHA providing secure and robust two-way communications capabilities.
No special equipment is necessary because the SmartPoint module automatically establishes the communication path to the Sensus Base Station.
Utilities today rely on big data to help make intelligent decisions about their energy needs.
A3 ALPHA meters can collect six channels of load profile information (for example, kWh or kVARh) and up to 15 configurable snapshot registers delivering even more information.
The SmartPoint module retrieves the data directly from the A3 ALPHA meter tables and transmits it over the secure FlexNet communications network.
