The Senva EM-PULSE is a compact, revenue-grade (ANSI C12.20 Class 0.2, 0.2% meter accuracy) energy meter with dual solid-state pulse outputs reporting import and export energy (kWh) at selectable scaling from 0.01 to 1k Wh per pulse. Its meter base is entirely low-voltage — all high-voltage connections live in the plug-in CVT Current/Voltage Transducers (sold separately) — with 1% system accuracy, 2 pulse inputs for multi-meter summing, DIN/screw/magnetic mounting, and made in the USA by Senva, Inc. (Buy American Act, BABAA, ARRA, and TAA conformant).
Senva EM-PULSE Pulse Output Energy Meter
The EM-PULSE installs quickly and safely. The unique design makes the meter entirely low-voltage: the high-voltage components are embedded in the Current/Voltage Transducer (CVT). Each CVT is individually calibrated, communicates digitally with the meter for superior noise immunity, and channels can be mixed or matched with a summed total — 1% total system accuracy.
Dual solid-state pulse outputs report import and export energy at selectable scaling, dropping into any pulse-counting BAS input, data logger, or utility monitoring system. Two pulse inputs accept additional meters for multi-meter pulse summing.

Key Features
Revenue-Grade Accuracy
0.2% meter accuracy to ANSI C12.20 Class 0.2 standards and 1% system accuracy with CVTs for V, A, kW, kVAR, and kVA — suitable for tenant billing, and meets the WA State Clean Buildings bill.
Dual kWh Pulse Outputs
Separate import and export energy pulse outputs (solid-state dry contact, N.O., 300mA / 40V max) with selectable scaling from 0.01 to 1k Wh per pulse.
Entirely Low-Voltage Meter Base
All high-voltage connections are contained in the CVT — the safest, fastest meter install on the market, and the base can be located outside the panel.
Plug-and-Play CVT Recognition
Each digitally calibrated CVT is automatically recognized and scaled by the meter — no manual CT scaling, no setup.
Multi-Meter Pulse Summing
2 pulse inputs accept additional EM-PULSE meters or other pulse-output meters set to the same scale; the meter aggregates the pulses and reports a total sum.
True 3-Channel Mix & Match
Three independent meter channels accept different voltages and currents per phase — ideal for HVAC equipment and mixed loads.

Frequently Asked Questions
Is this a revenue-grade meter?
Yes. The EM Series meets ANSI C12.20 Class 0.2 standards (0.2% meter accuracy), commonly referred to as ANSI revenue grade, and meets the performance standards of the Washington State Clean Buildings bill. System accuracy with CVTs is 1% for V, A, kW, kVAR, and kVA.
What CTs does this meter use?
It uses Senva CVT Current/Voltage Transducers exclusively (sold separately). Each CVT carries the high-voltage connection, senses both voltage and current, and communicates digitally with the meter — standard 0.333V CTs and analog Rogowski coils are not compatible. For 0.333V CT or analog Rogowski input, see the Senva EMX series.
Can multiple EM-PULSE meters be summed together?
Yes. The EM-PULSE accepts pulse inputs from one or more additional meters and aggregates them, reporting the pulses as a total sum. All meters must be set to the same pulse scale.
Does the installation require fusing?
Typically no. Under UL 240.21 tap-rule guidance, Senva CVTs may tap conductors without overcurrent protection, and Senva ships EM Series meters with no more than 10 feet of voltage reference wire per CVT. If a voltage reference run must exceed 20 feet, appropriate overcurrent protection (such as the CVT-FUSE kit) is required.
Can I mix different CVT sizes on one meter?
Yes. The meter operates as a true 3-channel device: each channel independently recognizes its CVT and auto-scales, so different amperage ranges and voltages can be mixed per phase — ideal for HVAC equipment and mixed loads.
Is this meter Buy American Act compliant?
Yes. The EM Series is manufactured in the USA by Senva in Beaverton, Oregon, and conforms to the Buy American Act, Build America Buy America Act (BABAA), ARRA Section 1605, and the Trade Agreements Act (TAA). The signed 2026 conformance declaration is available in the documentation section above.
