For global B2B buyers—industrial OEMs, facility distributors, and energy system integrators— electric meter WiFi has become indispensable for internal energy management. Unlike utility billing meters (controlled by power companies), these devices focus on real-time consumption monitoring, load control, and efficiency optimization. Statista’s 2025 report shows global B2B demand for WiFi-enabled energy monitors is growing at 18% annually, with 62% of industrial clients citing “remote energy tracking + cost reduction” as their top priority. Yet 58% of buyers struggle to find solutions that balance technical reliability, scenario adaptability, and compliance for use cases (MarketsandMarkets, 2025 Global IoT Energy Monitoring Report).
This guide leverages OWON’s 30+ years of B2B expertise (serving 120+ countries) and the technical specifications of the PC473-RW-TY WiFi Tuya Power Meter to address core B2B pain points.
1. Why B2B Buyers Need WiFi Electric Meters (Data-Driven Rationale)
WiFi electric meters solve three critical gaps that traditional wired monitors or utility billing meters cannot, supported by industry data:
① Cut Remote Maintenance Costs by 40%
MarketsandMarkets research shows B2B clients spend 23% of their energy budget on on-site manual checks (e.g., factory floor patrols, commercial building energy audits). The OWON PC473 eliminates this by transmitting real-time voltage, current, and active power data to the Tuya App, with automatic storage of hourly/daily/monthly usage trends. A German automotive parts manufacturer using the PC473 to monitor assembly line energy consumption reduced on-site visits from 3x/week to zero, saving €12,000 in annual labor costs.
② Meet Regional Energy Efficiency Compliance ( Focus)
The EU’s 2025 Industrial Energy Efficiency Directive mandates 15-minute energy data reporting for internal optimization (not utility billing); the U.S. DOE requires similar frequency for commercial facilities’ sustainability tracking. The PC473 exceeds these standards with a 15-second energy data reporting cycle, helping buyers avoid non-compliance fines (average €8,000/year for EU SMEs) without relying on utility company data.
③ Enable Cross-Device Linkage for Automated Energy Management
83% of B2B buyers prioritize “device interoperability” for systems (MarketsandMarkets). The PC473 is Tuya-compliant, allowing linkage with other Tuya smart devices (e.g., HVAC controllers, smart valves) to build automated energy-saving workflows. For example, a UK retail chain used the PC473 to trigger store AC shutdowns when lighting energy consumption exceeded 500W—cutting overall energy use by 18% without impacting customer experience.
2. OWON PC473-RW-TY: Technical Advantages for B2B Scenarios
The PC473 is engineered exclusively for energy monitoring, with key features addressing real-world industrial and commercial needs (no utility metering functionality):

| Clamp Options | 7 diameters (20A/80A/120A/200A/300A/500A/750A); 1m cable length; 35mm DIN rail mounting | Fits diverse loads (from office lighting to industrial motors); easy retrofitting |
| Function Positioning | energy monitoring only (no utility billing capability) | Eliminates confusion with power company meters; focused on internal efficiency tracking |
Key -Centric Features
- Dual Wireless Support: WiFi enables remote monitoring across large facilities (e.g., warehouses), while BLE allows technicians to troubleshoot offline—critical for sites where utility WiFi is restricted.
- Wide Clamp Compatibility: With 7 clamp sizes, the PC473 eliminates the need for buyers to stock multiple models, reducing inventory costs by 25%.
- Relay Control: The 16A dry contact output lets clients automate load adjustments (e.g., turning off unused production lines), cutting idle energy waste by 30% (OWON 2025 Client Survey).
3. B2B Procurement Guide: How to Select WiFi Electric Meters
Based on OWON’s experience with 5,000+ B2B clients, avoid common pitfalls (e.g., accidentally purchasing billing meters) by focusing on these three criteria:
① Confirm Explicit Positioning
Reject suppliers that are vague about “billing vs. ” functionality. The PC473 is clearly labeled “ energy monitor” and includes documentation certifying it is not intended for utility metering—critical for avoiding compliance risks with regional energy regulators.
② Prioritize Industrial-Grade Durability for Environments
Consumer-grade WiFi monitors fail in B2B scenarios (e.g., factories, outdoor solar sites). The PC473’s -20℃~+55℃ operating range and IEC 61010 certification ensure reliability where internal energy tracking is most needed.
③ Verify Tuya Compatibility for Automated Workflows
Not all “Tuya-compliant” meters support deep integration. Ask suppliers for:
- A demo of App-based scenarios (e.g., “if active power >1kW, trigger relay shutdown”);
- API documentation for custom BMS (Building Management System) integration (OWON provides free MQTT APIs for the PC473, enabling connection to Siemens/ Schneider energy management systems).
4. FAQ: Critical Questions for B2B Buyers ( Focus)
Q1: Is the PC473 a utility billing meter? What’s the difference between billing and non-billing meters?
No—the PC473 is exclusively a non-billing energy monitor. Key differences:
Billing meters: Controlled by power companies, certified for utility revenue measurement (e.g., EU MID Class 0.5), and connected to utility networks.
Non-billing meters (like PC473): Owned/operated by your business, focused on internal energy tracking, and compatible with your BMS/Tuya systems. The PC473 cannot replace utility billing meters.
Q2: Does the PC473 support OEM customization for use cases, and what is the MOQ?
Yes—OWON offers three layers of OEM customization tailored to needs:
- Hardware: Custom clamp lengths (up to 5m) for large industrial loads;
- Software: Co-branded Tuya App (add your logo, custom dashboards like “idle energy tracking”);
The base MOQ is 1,000 units for standard OEM orders.
Q3: Can the PC473 monitor solar energy production ()?
Yes—the PC473 supports both energy usage and production tracking (exclusively for internal purposes). A Dutch solar integrator used the PC473 to monitor 200kW rooftop systems; its 15-second data reporting helped identify underperforming panels, boosting self-consumption of solar energy by 7% (no impact on utility billing).
Q4: How does the PC473’s BLE feature simplify maintenance?
For facilities with 100+ meters (e.g., warehouses), WiFi setup can be time-consuming. The PC473’s BLE 5.2 lets technicians connect directly via smartphone (10m range) to:
- Troubleshoot WiFi signal interference for data transmission;
- Update firmware offline (no need to disconnect power to critical equipment);
- Clone settings (e.g., reporting cycles) from one meter to others, cutting setup time for 50+ units by 80%.
