Overview

VISIONTEK SM-38 Three Phase ac Static Transformer Operated Smart Energy Meter from Linkwell is designed for revenue metering application for high value commercial & industrial (LT) consumers and for energy audit purposes at distribution transformer side.

36SM Single Phase Energy Meter

Smart Meters have versatile features that enable the utilities to configure the meter remotely such as downloading the TOD tariff into the meter, configure to Bi-directional metering (Net Metering), firmware upgrade, etc....

VISIONTEK SM-38 has a field replaceable communication module that offers two-way communication for meter data transfer. The communication module is swappable between different communication technologies as specified in IS 16444 Part 2 such as 6LoWPAN or Cellular (GSM/GPRS/3G/4G LTE)

Application Areas

Residential metering
Commercial metering
Sub-tenant metering
