    Wide Range Valve-controlled Ultrasonic Water Meter

    Wide Range Valve-controlled Ultrasonic Water Meter

    Release Date:

    2026-07-22

    Product Description:

    Wide-Range Valve-Controlled Ultrasonic Water Meter‌ is a fully electronic intelligent flowmeter utilizing the ‌ultrasonic time-of-flight (TOF) principle‌ to measure flow rate by detecting the time difference of ultrasonic signals propagating in downstream and upstream directions.

    Product Highlights:

    Its core advantages include ‌no moving mechanical parts, wide dynamic range (R≥800), high accuracy, and low-flow detection capability‌.

    Wide Range Valve-controlled Ultrasonic Water Meter Technical Advantages

     

    • ‌Ultra-Wide Dynamic Range:‌ R800 flow range ratio achieves ‌droplevel measurement accuracy‌, with ‌≤±2% error‌ in low-flow detection.

    • ‌Dual-Power Supply Design:‌ Separate power modules for metering and functional circuits ensure ‌dual protection‌ for measurement precision and system stability, effectively suppressing ‌common-mode interference‌ to guarantee long-term data reliability.

    • ‌Intelligent Sensing System:‌ Built-in ‌high-precision pressure sensors‌ monitor pipeline pressure in real time, paired with a patented temperature compensation algorithm‌ for dynamic calibration ‌without additional sensors‌.

    • ‌Precise Valve Control:‌ Supports ‌remote adjustment of physical valve opening‌ (5 adjustable positions: 0°, 25°, 50°, 75°, 100°).

    • ‌Omni-Directional Installation:‌ U0D0 design eliminates ‌straight pipe requirements‌, allowing ‌horizontal/vertical installation without compromising accuracy‌.

    • ‌Data Storage Security:‌ ‌Power-cut protection‌ ensures storage of hourly/daily/monthly/annual records, with data retention ‌>15 years‌.

    • ‌Bidirectional Flow Measurement:‌ Independently measures forward/reverse flow‌, with real-time flow direction display.

    • Military-Grade Protection:‌ ‌IP68 rating‌ with ‌triple rubber sealing + full potting technology‌, ensuring ‌zero leakage‌.

    • ‌Long-Life Design:‌ ‌No moving mechanical parts‌; built-in ‌lithium-manganese battery‌ reduces self-discharge (‌<1%/year‌), with ‌theoretical lifespan ≥15 years‌.

    • ‌High-Temperature Adaptability:‌ ‌T70 rating‌ guarantees stable operation at ‌70°C‌
