VoltDrop™ is a wireless, self-powered energy sensor for single-phase, three-phase, and multi-phase systems. It measures voltage, power factor, real and apparent energy, and amperage with Rogowski coils or CTs — and harvests its own power from the lines it monitors.
VoltDrop™ drops into your existing electrical system and uses high-accuracy Rogowski coils or current transformers to measure current and voltage together. It transmits real-time data over LoRaWAN without an external power supply, harvesting power from the energy it measures, and every sensor is calibrated for consistent, accurate readings.
Wrap the coils or CT heads around your single- or multi-phase cables, mount the unit, and connect the ground wire.
Add VoltDrop™ to a LoRaWAN network in minutes with the Vutility app.

Real and apparent energy, voltage, amperage, and power factor in one device.
24" Rogowski (2500A), 8" Rogowski (2000A), or a 300A CT for low-amperage precision.
Runs on the energy it measures — nothing to plug in or recharge.
Surfaces patterns, spikes, and inefficiencies that hourly billing data hides.
LoRaWAN communication that holds up inside metal enclosures.
Feeds CloudVU or your own LoRaWAN network and tools.
