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 temperature/pressure detection with T.P.Z compensation,
converting operating volume to standardized flow measurement.
✓ Advanced micro-power consumption technology supports long-term
operation via internal battery power.
✓ High-capacity storage with anti-tamper protection for critical
data modifications and historical records.
✓ Real-time data retention safeguards against power interruptions,
ensuring permanent parameter preservation.
✓ Optional embedded GPRS/NB-IoT modules enable wireless meter
reading systems with battery-powered daily transmissions (1/day),
requiring no external power supply.
Application
In the petroleum, chemical, metallurgy, water supply, paper and
other industries with a wide range of applications.
