Electric Sensors & Meters

Electrical energy monitoring through a variety of products at a mix of price points. Our customers look to gain additional insight into their site's energy use beyond their utility bill. We focus on collecting data from the site's main utility meter and subsequent sub-mains at the main distribution panel, leveraging a variety of products to accomplish the monitoring objectives.

Why It Matters

Electricity is an essential energy resource and enabler of operations. It is critical for motor, HVAC, and lighting loads throughout a site. Utility bills only show total consumption — not how, when, or where energy is used. Submetering breaks down usage by area, process, or equipment, revealing inefficiencies and cost drivers. Electric meters are not just about reading kWh — they are about turning data into action, providing the transparency and control needed to run your facility more efficiently, reliably, and sustainably.

Key Selection Factors

• Revenue-grade (ANSI C12.20 Class 0.2/0.5) vs. monitoring-only accuracy
• Voltage class (208V, 480V, 600V) and system type (wye, delta)
• CT type: solid-core, split-core, or flexible Rogowski coils — verify opening/loop size fits bus bar dimensions
• Communication protocols: Modbus RTU/TCP, BACnet MSTP/IP, pulse outputs, LoRaWAN, Wi-Fi, or cloud-ready options
• Single-load meters vs. multi-circuit monitors (3, 12, 24, or 48 channels)
• Form factor: panel-mounted, DIN rail-mounted, or enclosure-based (NEMA 1/3R/4 or IP-rated for outdoors/harsh environments)
• Advanced features: web interface, data logging, alarm/threshold notifications, Time-of-Use (TOU) capability

Installation Guidelines

• Verify voltage level and system type (3-phase 4-wire wye, 3-phase 3-wire delta, 1-phase split) and match meter configuration settings
• Select CTs rated for expected current levels with matching ratios — install with correct polarity orientation (H1 toward source/load per meter instructions)
• Always short CTs when not connected to a meter to avoid open-circuit hazards
• Follow NFPA 70E (Arc Flash Safety), NEC, and OSHA lockout/tagout procedures — use insulated tools and PPE
• Mount meters in a cool, dry, vibration-free environment — avoid installing near large VFDs or transformers
• Set communication addresses, baud rate, parity, and termination resistors; document the network map
• After installation, verify CT wiring, polarity, readings against expected values, and BMS/EMS communications
• Label CTs, conductors, and meter terminals clearly — maintain as-built documentation and wiring diagrams
