    Low compressed air
    Alkanes with inert gas industry
      Novel design, beautiful appearance
      Use of long maturity, normal operation of the time limit for 10 years, rotor precision machining and balance, high strength, surface treatment, no wear rotation, the exquisite design and ensure the long-term normal work flow process.
      High precision, high reliability, use for a long time do not need to adjust, not affected by medium conditions change.
      The pressure loss is small, different specifications 0.07 kpa ~ 0.55 kpa pressure loss

  TBYY roots gas flowmeter is a kind of mechanical counter displacement measuring instrument, its principle is that when the gas being measured into the inlet side of the flow meter, drive the rotor rotation, every week there is a certain volume flow out of the exit row, that is to choose working principle of the constant displacement, and then transferred to counter by magnetic FGC body, show the measured the volume of a gas quantity, roots gas flowmeter can be configured at low frequency pulse transmitter and volume correction instrument, pressure compensating, the compression factor correction for temperature, on the volume correction instrument can display the gas standard volume flow rate.d on displacement measurement principle, characterized by high precision, wide flow rate range, compact structure, strong, straight pipe inlet and outlet without, service life of life is long, suitable for installation in the occasion of narrow environment, accurate measuring load change in harsh climate conditions of large gas flow.The product is novel design, beautiful shape, light weight, high precision, easy installation and use, such as points.
