Core Functionality

Ultrasonic water meters utilize ultrasonic transit-time difference measurement technology to accurately monitor water consumption. Built-in ultrasonic sensors measure flow velocity in both downstream and upstream directions in real time, converting this data into precise flow volume readings . Unlike traditional mechanical meters, these devices contain no moving parts, eliminating mechanical wear, friction, and debris jamming issues that cause accuracy degradation over time .

Key functional capabilities include:

Bidirectional flow measurement – detects both forward and reverse flow with equal precision

Automatic Meter Reading (AMR) – enables remote consumption data collection without physical intervention

IoT connectivity – built-in NB-IoT, LoRa, LoRaWAN, M-Bus, RS-485, and 4G communication options support real-time data transmission

Proactive fault alerts – notifications for low battery, tampering, leaks, and system abnormalities

Self-diagnostic logging – internal data logging capacity supports system diagnostics and leak detection
