VA 521 Flow meter 06960521 1789 CS-Instrument Vietnam

 

 

Product Highlights

  • Direct mass flow measurement with output of standard volume flow — no need for separate pressure or temperature measurement.

  • Compact design ideal for tight spaces; no inlet or outlet straight runs required thanks to the integrated flow straightener.

  • Delivers high accuracy across a wide flow range, from low to high flow rates.

  • Easy sensor installation and removal — the built-in measuring section stays in the pipeline during sensor cleaning or recalibration and can be sealed with a cap when not in use.

  • No moving parts, resulting in minimal maintenance.

  • Suitable for compressed air and non-corrosive gases such as nitrogen, oxygen, argon, helium, etc.

  • Equipped with standard interfaces: 4–20 mA, pulse output, and Modbus RTU (RS485).

  • Optional communication interfaces include: Modbus TCP (Ethernet), Power over Ethernet (PoE), and M-Bus.

  • Pressure range: up to 40 bar

  • Temperature range: up to 80°C

  • Built-in display for real-time measurement readings.

  • Available in sizes from ½" to 2".

  • Display buttons allow for user-friendly parameter settings and resetting of the main counter.

  • Supports flow velocities up to 224 Nm/s.

  • Exceptional measurement precision with ±1.5% or ±1% of the measured value, and ±0.3% of the full scale.
