気体用マスフローメータ(マルチポイント挿入形)_熱式質量流量計

気体用マスフローメータ(マルチポイント挿入形)_熱式質量流量計

K-BAR2000B is a thermal mass flowmeter for gas measurement. Its measuring principle takes advantage of the fact that calorie amount taken away from the heated sensor by a fluid flow is correlated to the mass flow. The sensor inserted in the pipeline samples and averages the flowrate at multiple points through the pipe to infer the total flowrate.

  • energy saving
  • high function,high performance
  • high and low temperature service model
  • explosionproof

FEATURES

1. Supports large scale duct and stack.
2. Installation of multiple sensors (four maximum) makes preparation of long straight pipe for large bore pipe unnecessary.
3. Allows measurement of flowrate lower than pitot tube.
4. Measurement is possible at high temperature (260°C and 500°C).
5. High durability by the use of a sensor of all-welded construction.
6. Easy to install.
7. Wide range of 0 to 55 m/s (normal)
8. Very quick response
9. Concurrent measurement of temperature and mass flowrate at each sensor position
10. Compensation of pressure and temperature is unnecessary.
