The Ultrasonic Residential Water Meter (RWM) is a battery-operated, high-accuracy device designed for outdoor fixed installations. It measures flow using the Transit-Time Differential Measurement Principle, with no moving parts, ensuring zero maintenance, long-term reliability, and excellent durability. Certified for drinking water, OIML R49, ISO 4064, IP68, it ensures robust performance in varied residential environments.

Water utilities face challenges in areas where LoRa inf rastructure is absent or where meter installations are geographically scattered. Manual readings lead to billing disputes, operational delays, leakage losses, and no visibility into consumption patterns. A centralized method for real-time monitoring across independent homes, villas, resorts, hotels, and small commercial establishments is required, without dependency on local gateways or reader visits.

To overcome these challenges, SBEM provides the RWM with AMI (NB-IoT / GPRS). Each meter transmits consumption and diagnostic data directly through cellular networks (NB-IoT / GPRS(2G/4G) to the cloud server, eliminating the need for gateways or local reading devices. All data is available on SenSphere Web App, enabling accurate billing, leak detection, reverse flow alarms, and real-time visibility f rom any remote location.
