These meters communicate over LoRa, low power long range radio communication protocol. It can integrate into a Lora gateway and uplink via the gateway to a cloud server. Ultrasonic water meters on LoRa wireless protocol is suited for precision measurement in a spread-out space, places where wired networking is not feasible. These meters are best suited for villa communities and large industrial spaces.

Aegir meters are tested by Flow Control Research Institute (FCRI - a premier standards testing laboratory under Government of India) for accuracy and other parameters. Apart from its high accuracy, tests also reveal that these meters cause extremely low pressure drops (less than 8% of ISO allowed drop). Also, the meters are rated for a high temperature range (up to 80 C) and high pressure withstanding capability.
