Overview

Smart Meter is an alternating current static watt-hour meter with time of use registers, internal connect /disconnect switches with two-way communication capability. VISIONTEK SM-12 Single Phase Smart Meter from Linkwell is designed to meter residential and small commercial energy consumers in single-phase distribution networks.

36SM Single Phase Energy Meter

Smart Meters have versatile features that enable the utilities to configure the meter remotely for load shedding in case of emergency/peak load conditions or when the demand is exceeding the supply, download the TOD tariff into the meter, configure to Bi-directional metering (Net Metering), from post-paid to pre-paid mode, etc..

Smart Meters also enable the consumers in managing their loads and empower the consumers to make informed choices about the usage of energy real time information through mobile-phone apps

Application Areas

Residential metering
Commercial metering
Sub-tenant metering
