IoT Ultrasonic Water Meter STBU
Bulk Ultrasonic Water Meter for DN50–DN300
The bulk ultrasonic water meter is engineered for precise high-flow measurement in utility, commercial, and industrial water systems. Featuring a wide dynamic range up to R800, it ensures accuracy from low to peak flow, making it ideal for district metering, building consumption tracking, and large-scale infrastructure. With built-in IoT connectivity and robust IP68 protection, this meter supports smart water network deployments across demanding environments.
This ultrasonic water meter delivers high-accuracy flow measurement and real-time data communication for remote reading, leak detection, and smart billing. It’s ideal for smart city AMI deployments and compatible with LoRaWAN, 4G LTE Cat.1, NB-IoT, Bluetooth®, and Sigfox® protocols.
🔹 Key Features
Exceptional Measurement Accuracy (R500–R800)
Delivers high-resolution ultrasonic readings across a wide dynamic range, ensuring accuracy in both low and high flow conditions — ideal for modern smart metering requirements.
Full IoT Integration
Compatible with LoRaWAN®, 4G LTE Cat.1, NB-IoT, Sigfox®, and Bluetooth® for seamless remote data collection, system integration, and cloud-based analytics.
Durable IP68-Rated Construction
Built to operate reliably in underground, outdoor, or industrial environments with full protection against dust, moisture, and mechanical stress.
Real-Time Alarm Functions
Leak detection, reverse flow, burst pipe, and tamper alarms help utilities ensure supply reliability and reduce losses.
Flexible Installation and Low Maintenance
Supports both horizontal and vertical installations; non-mechanical design minimizes servicing and extends operational life.
