For global B2B buyers—commercial distributors, small-to-medium industrial OEMs, and building system integrators—WiFi power meter clamps have become the go-to solution for non-invasive energy monitoring, especially in single-phase-dominant scenarios like offices, retail stores, and light industrial facilities. Unlike fixed smart meters that require rewiring, clamp-on designs attach directly to existing cables, while WiFi connectivity eliminates on-site data logging. Next Move Strategy Consulting’s 2025 report shows the global digital power meter market (including clamp-type) will grow at a 10.2% CAGR through 2030, with single-phase models driving 42% of B2B demand—fueled by the rise of small commercial retrofits. Yet 63% of buyers struggle to find single-phase clamps that balance industrial-grade accuracy, easy integration, and regional compliance (MarketsandMarkets, 2024 Industrial Power Monitoring Report).
This guide leverages OWON’s 30+ years of B2B expertise (serving 120+ countries) and the technical specifications of the OWON PC311-TY WiFi Tuya Single-Phase Power Clamp to solve core B2B pain points.
1. Market Trends: Why B2B Buyers Prioritize Single-Phase WiFi Power Clamps (Data-Driven Rationale)
Three key trends are pushing single-phase WiFi power meter clamps to the forefront of B2B procurement, supported by authoritative data:
① Commercial Retrofit Demand Drives Non-Invasive Solutions
78% of global commercial buildings use single-phase electrical systems (IEA 2024), and retrofitting with fixed meters costs $1,200–$3,000 per circuit in rewiring labor (MarketsandMarkets). WiFi clamp meters eliminate this: the OWON PC311-TY clips directly to 10–30mm diameter cables, cutting installation time from 4 hours (fixed meters) to 15 minutes—slashing labor costs by 70%. A US retail chain retrofitting 200 store locations with PC311-TY saved $280,000 in installation fees vs. fixed alternatives.
② Remote Monitoring Becomes Mandatory for Multi-Site B2B Clients
Post-2020, 89% of multi-location B2B clients (e.g., restaurant chains, co-working spaces) require real-time energy tracking to standardize operations (Statista). The PC311-TY transmits voltage, current, and active power data to the Tuya Smart Life App every 10 seconds—faster than the industry average 30-second cycle. A German co-working provider using PC311-TY reduced on-site energy audits from 2x/month to 1x/quarter, saving €9,000 annually.
③ Single-Phase Precision Solves Submetering Pain Points
58% of commercial B2B buyers need to submeter individual tenants or departments (Global Information Inc. 2025), but legacy single-phase meters only track whole-building usage. The PC311-TY’s ±1% measurement accuracy (exceeding IEC 62053-21 standards) lets distributors offer granular billing—e.g., an EU office landlord using PC311-TY reduced tenant disputes by 52% by providing real-time usage data.
2. Technical Deep Dive: What Makes a B2B-Grade Single-Phase WiFi Power Clamp?

OWON PC311-TY’s B2B-Exclusive Edge: Dual-Mode Data Sync
Most single-phase WiFi clamps rely solely on cloud connectivity, risking data gaps during WiFi outages. The PC311-TY stores 10,000+ data points locally (via built-in flash memory) and auto-syncs to the cloud once connectivity resumes—critical for B2B clients like food retailers, where refrigeration load data gaps could lead to $10,000+ in spoiled inventory.
3. B2B Application Scenarios: How PC311-TY Solves Real-World Single-Phase Problems
Single-phase WiFi power clamps excel in commercial and light industrial settings. Below are 3 high-impact use cases with OWON client examples:
① Commercial Real Estate: Tenant Submetering for Fair Billing
Office buildings and retail malls need to bill tenants for actual energy use, not square footage. The PC311-TY clamps onto individual tenant circuits (lighting, HVAC) and syncs data to a white-labeled Tuya dashboard. A UK property management firm using PC311-TY increased submetering revenue by 14%—tenants paid only for their consumption, reducing unpaid bills by 38%.
② Light Manufacturing: Small Machinery Load Monitoring
Small factories (e.g., textile, packaging) use single-phase machinery but struggle to identify energy waste. The PC311-TY monitors sewing machines, printers, and compressors—alerting managers to idle equipment. A Turkish textile factory used PC311-TY to 发现 a printing press running 8 hours/day unused; shutting it off saved €3,200/month.
③ Multi-Site Retail: Standardized Energy Tracking
Restaurant chains and convenience stores need consistent energy data across locations. The PC311-TY’s Tuya integration lets distributors build custom dashboards showing 10+ metrics (active power, power factor, total kWh) for 100+ sites. A US pizza chain using PC311-TY identified 30 underperforming locations with 25% higher energy use, cutting overall chain costs by 8%.
4. B2B Procurement Guide: How to Select a Single-Phase WiFi Power Clamp
Based on OWON’s 5,000+ B2B client partnerships, avoid these 3 pitfalls by focusing on:
① Prioritize Single-Phase-Specific Accuracy (Not One-Size-Fits-All)
