Features

  • MEMS-based gas flow meter boasts a high sensitivity, allowing a very small start flow, used for instantaneous flow testing and flow accumulation calculations, applicable to air, compressed air, oxygen, nitrogen, and other inert gases
  • Compressed air nitrogen flow meter has a built-in sensing chip for thermal mass flow measurement, no temperature and pressure compensation, ensuring a high accuracy
  • Nitrogen air flow meter features an LCD display to show instantaneous flow and cumulative flow at the same time as well as the battery level, 180 rotating for reading from any angle
  • Portable air flow meter has a compact body with G 1/4 thread, easy to set up and install, designed with RS485 communication interface
  • Nitrogen flow meter allows 2 power supply methods, either powered by mains power or by 4x AA battery (not included)
  • NOTE: To ensure the measurement accuracy of the flow meter, it needs to be preheated for 1min before use.

  • Good product. Poor documentation.
Bought this meter to adjust Argon flow for TIG welding. The printed manual is in Chinese. The "English manual" QR code on the box leads to a broken link. You can find the proper English manual using this phrase "Gas Mass Flow Meter VC.3". That's the reason for 4 star instead of 5. Overall I like it. It can be powered via USB-C, which is good for my application. The unit is calibrated for air, thus I need to multiply the value by 1.4 for Argon flow. Gas conversion factor can be reprogrammed, as shown in the English manual, but I did not do it yet. I only did zero flow calibration after it showed 0.38 slpm when the valve was closed. It is expensive, but it solved my too-much-too-little Argon problem. The Argon pressure was reduced to 1.5 bar upstream of the flow meter, and the adjusting needle valve was downstream of the meter. ... show more
