Narrative

Technical Innovation & Quality Heritage

YTL’s Multi-function Smart Meters are high-end analytical instruments designed for advanced energy auditing and power quality management. Unlike basic kWh meters, these multi-functional devices capture a comprehensive range of electrical data, including instantaneous voltage, current, power factor, frequency, and Total Harmonic Distortion (THD). As a premier manufacturer, Zhejiang Yongtailong has built these meters to provide a surgical level of detail into the electrical health of your facility. They feature high-precision Class 0.5s measurement and massive non-volatile memory for extensive load profiling and event logging. Whether you are troubleshooting electrical noise in a factory or optimizing energy efficiency in a green building, our multi-function meters provide the deep data insights required to make informed engineering and financial decisions.

Product Application

  • Industrial Power Quality Audit
  • Critical Hospital Infrastructure
  • Enterprise Energy Management

Industrial Power Quality Audit

Used to diagnose issues in manufacturing plants where sensitive electronic equipment or robotics are failing due to "dirty" power. These meters track harmonic distortion and voltage transients in real-time, allowing electrical engineers to identify the source of the noise and implement filtering solutions to prevent expensive equipment downtime and repairs.

Critical Hospital Infrastructure

In medical facilities, power reliability is a matter of life and safety. Multi-function meters monitor the health of the electrical grid and backup generators, providing detailed logs of every voltage sag or frequency shift. This ensures that the facility's power quality remains within the strict tolerances required for medical imaging and life-support systems.

Enterprise Energy Management

Ideal for corporate sustainability programs and ISO 50001 certification. These meters provide the granular data needed to build a complete profile of a company's energy consumption. By analyzing the power factor and demand peaks, businesses can implement targeted energy-saving measures that result in significant long-term cost reductions.

Product Advantages

Surgical Precision

Certified to Class 0.5s accuracy, ensuring that even very small variations in power consumption are captured—essential for high-value revenue billing and accurate auditing.

Comprehensive Harmonic Analysis

Measures individual harmonics up to the 31st order, giving you a full spectrum view of your power quality and helping to protect sensitive electronic components.

Customizable Event Alarms

Users can program custom thresholds for voltage, current, or demand, triggering immediate digital outputs or notifications when parameters fall outside of safe limits.

Frequently Asked Questions

  • Q: What is the benefit of "Class 0.5s" accuracy?

    A: Class 0.5s is much more precise than standard Class 1.0, especially at very low current loads. This is required for high-current industrial billing where even small errors can cost thousands.

  • Q: Does this meter show harmonics on the screen?

    A: The basic values like THD can be viewed on the LCD, but for the full 31st order harmonic spectrum, we recommend viewing the data through the RS485/software interface.

  • Q: Can it log power outages?

    A: Yes, it features an extensive event log that records the exact timestamp of every power failure, voltage sag, and swell event for up to 1,000 instances.

  • Q: Can I connect multiple software platforms at once?

    A: Many of our multi-function models feature dual RS485 ports or Ethernet, allowing you to send data to a local SCADA system and a cloud EMS simultaneously.

  • Q: Does it measure reactive power?

    A: Yes, it provides full 4-quadrant measurement, including active, reactive, and apparent power, as well as the power factor for each individual phase.
