Narrative

Technical Innovation & Quality Heritage

YTL’s High Precision Revenue Meters are the elite tier of energy measurement, specifically engineered for wholesale electricity markets, large-scale industrial billing, and grid-tie substations. While standard residential meters offer Class 1.0 accuracy, our high-precision series provides Class 0.2s or Class 0.5s measurement, meeting the most stringent international standards for financial settlements. As a specialized manufacturer, Zhejiang Yongtailong utilizes ultra-stable voltage dividers and low-drift current sensors to ensure that accuracy is maintained across a wide temperature range and varying load conditions. These meters are equipped with advanced data security features, multi-channel load profiling, and comprehensive power quality analysis. They are the trusted choice for utilities and high-energy enterprises that require absolute certainty in their billing data and total transparency in their energy supply chain.

Product Application

  • Inter-Utility Power Exchange
  • Heavy Industrial Smelters
  • High-Tech Research Facilities

Inter-Utility Power Exchange

Used at the boundary points where different utility companies or regional grids exchange large amounts of electricity. Because the financial stakes are so high at these transfer points, the Class 0.2s accuracy is mandatory to ensure that every megawatt-hour is accounted for with scientific precision, preventing multi-million dollar billing discrepancies between power generation and distribution entities.

Heavy Industrial Smelters

Ideal for aluminum or steel smelting plants that consume massive amounts of power in 24/7 operations. These facilities require ultra-high precision to monitor their specific energy consumption per ton of product. The meter's ability to handle high harmonic distortion ensures that even in the "noisy" electrical environment of an induction furnace, the revenue billing remains 100% accurate and verifiable.

High-Tech Research Facilities

Designed for laboratories and semiconductor fabrication plants where even the slightest power quality fluctuation can ruin millions of dollars in sensitive equipment or experiments. The meter provides a surgical level of detail into voltage transients and frequency stability, acting as both a billing tool and a critical scientific instrument for facility-wide power quality assurance.

Product Advantages

Unrivaled Measurement Stability

Uses premium components with extremely low thermal drift, ensuring that the meter remains within its 0.2s accuracy class regardless of seasonal temperature changes or load fluctuations.

Ultra-High Harmonic Analysis

Capable of measuring individual harmonics up to the 63rd order, providing the most detailed view possible of grid health and helping to identify the source of complex electrical interference.

Military-Grade Data Logging

Features multiple independent load profile channels with high-resolution logging, ensuring that every second of energy data is securely backed up and available for forensic audit.

Frequently Asked Questions

  • Q: What does the "s" in "Class 0.2s" stand for?

    A: The "s" stands for "Special". It means the meter maintains its high accuracy even at very low current levels (down to 1% of the rated current), which standard meters cannot do.

  • Q: Is this meter certified for fiscal billing?

    A: Yes, our high-precision meters are designed to meet or exceed MID (Europe) and ANSI (Americas) standards for legal, fiscal revenue billing in wholesale markets.

  • Q: Can I use this meter with a PC?

    A: Yes, the meter includes an optical port for local technician access and RS485/Ethernet ports for remote connection to professional AMI or energy management software.

  • Q: Does it support 4-quadrant measurement?

    A: Absolutely. It provides comprehensive tracking of active, reactive, and apparent power in all four quadrants, which is vital for managing grid-tie substations.

  • Q: What is the benefit of 63rd order harmonic analysis?

    A: It allows engineers to identify very high-frequency noise that can interfere with sensitive medical or laboratory equipment, which standard meters (31st order) would miss.
