Airflow that drifts off-target wastes energy and undermines ventilation. Using differential pressure across two ports, this sensor derives air velocity to give HVAC and facility teams a clear read on duct and system performance.

Readings stream automatically to the Emergent Metering cloud, where every measurement is logged and time-stamped for you. Set the thresholds that matter and the system alerts your team by text, email, or phone call the moment a reading drifts out of range — so problems get caught before they become downtime, spoilage, or a compliance miss.
