Sun-AP Ecopower is an authorised distributor of Non-Tariff Meters by Secure Meters in India. We supply a complete range of non-tariff energy meters for energy monitoring, submetering, load management, and power quality applications across industrial, commercial, and solar installations pan-India.
A Non-Tariff Meter is an energy meter used for internal monitoring and measurement purposes rather than for utility billing or revenue transactions. Unlike a tariff meter which is a legally certified billing instrument between a consumer and a DISCOM – a non-tariff meter is installed within a premises to monitor energy consumption at the feeder, department, machine, or tenant level.
The data from a non-tariff meter is used for internal decision-making: identifying energy waste, tracking department-wise consumption, managing load distribution, auditing power quality, and building an energy management system. They do not require BIS certification for billing use but must still meet accuracy and measurement standards relevant to their application.
Non-tariff meters are deployed anywhere inside a facility where you need visibility into energy consumption without it being tied to a billing transaction:
Both serve important roles – the tariff meter determines what you pay, the non-tariff meter tells you why and where you’re consuming.
Most industrial and commercial consumers receive a single utility bill for the entire premises. Without internal submetering, there is no visibility into which department, feeder, or equipment is consuming the most energy. This makes it impossible to identify waste, set consumption targets, or verify the impact of energy efficiency initiatives.
Non-tariff meters solve this by creating a granular layer of energy data inside the facility. When integrated with an energy management system or SCADA platform via Modbus or BACnet, they provide continuous, time-stamped consumption data across every monitored point enabling informed decisions on load scheduling, power factor correction, tariff optimisation, and equipment efficiency.
For solar installations, non-tariff meters at the inverter output provide generation data that feeds into monitoring dashboards and performance verification reports. Explore our Multifunctional Meters range for advanced variants with full power quality and communication capability.

A non-tariff meter is used for internal energy monitoring within a premises — tracking consumption at feeder, department, machine, or tenant level. The data is used for energy auditing, load management, SCADA integration, and cost allocation, not for utility billing.
HT metering points in India typically require Class 0.2S accuracy as per IS 14697 and IEC 62053-24 standards. LT connections generally use Class 1 or Class 0.5 meters depending on the DISCOM specification.
No. Since non-tariff meters are not used for legal billing between a utility and a consumer, they do not require BIS certification. However, they must meet accuracy and communication standards relevant to the application.
Yes. Most non-tariff meters support RS485 Modbus RTU as standard. Advanced models also support Modbus TCP, BACnet, Profinet, and IEC 61850 — making them compatible with virtually all SCADA, BMS, and EMS platforms.
A multifunctional meter is a type of non-tariff meter. All multifunctional meters are used for monitoring purposes, but a non-tariff meter is a broader category that includes simpler single-parameter panel meters as well as advanced multifunction instruments.
Yes. We supply non-tariff meters for solar inverter output monitoring, generation tracking, and SCADA integration for both rooftop and utility-scale solar installations. Contact us at +91 88844 90100 for product recommendations.
