Features
✓ High accuracy, excellent repeatability, and wide rangeability (up
to 1:20).
✓ Integrated rectifier design reduces straight pipe requirements
(Front ≥2DN, Rear ≥1DN).
✓ 360° rotatable volume corrector enables easy reading in various
installation configurations.
✓ Low rotational speed ensures long lifespan with low pressure loss
and high precision.
✓ Utilizes high-precision digital temperature sensors and
temperature-compensated digital pressure sensors, delivering
superior measurement stability with minimal temperature drift.
✓ Automatic Compensation: Features automatic temperature/pressure
detection with T.P.Z compensation, converting operating volume to
standardized flow values.
✓ Long Battery Life: Advanced micro-power consumption technology
enables extended operation via internal battery.
✓ Secure Data Management: High-capacity storage with anti-tamper
protection for critical parameter modifications and historical data
records.
✓ Power Failure Resilience: Real-time data retention safeguards
parameters permanently against power interruptions.
✓ Wireless Ready (Optional): Embedded GPRS/NB-IoT modules support
battery-powered wireless meter reading systems with daily data
transmission (1/day), eliminating need for external power.
Application
In the petroleum, chemical, metallurgy, water supply, paper and
other industries with a wide range of applications.
