The UM-1 meter computes flow rate by measuring the propagation time difference of ultrasonic pulses moving upstream and downstream in the fluid, paired with temperature compensation to deliver high measurement precision.
Free of any wearing mechanical internal parts, it delivers extended service life and minimal ongoing maintenance costs. With support for multiple communication protocols, it enables remote meter reading and streamlined centralized system management.

· High-Precision Metering
Adopting picosecond-grade metering chip and ultrasonic time-difference technology, it features a turndown ratio of 800:1 to ensure precise and reliable flow measurement.

· Ultra-Long Battery Life
It features an ultra-low-power circuit design. A single lithium battery enables stable operation for 8 to 12 years, effectively cutting maintenance and replacement expenses.

· Data Storage
It stores multi-dimensional water consumption records, including hourly, daily and monthly data, as well as fixed and instantaneous readings. All data is preserved long after power outages to guarantee complete data integrity.

· Multi-Scenario Alarms
It supports alarm functions for low voltage, empty pipe, backflow, abnormal temperature, leakage and pipe burst. All alarm events are recorded, and relevant status is displayed on the LCD for rapid troubleshooting.

· Bi-Directional Metering
It delivers accurate bi-directional flow measurement for effective monitoring of return pipelines. Comprehensive and dependable data fully satisfies metering requirements for complex pipe networks.

· Flexible Billing Support
It connects with cloud platforms and supports local prepaid, cloud prepaid and hybrid billing modes,being compatible with various payment channels for enhanced user convenience.
