MASS-STREAM®

The trade mark MASS-STREAM® represents a thermal measurement principle for the mass flow of gases, relatively independent of pressure and temperature.


Characteristics:
  • Direct mass flow measurement and control can be used for a wide variety of applications.
 MASS-STREAM®
  • Mass flow measurement and control by means of the through-flow principle

    • Digital model series D-6300

      • Minimum flow range      0.01 ... 0.2       ln/min (Air)
      • Maximum flow range     100 ... 5,000    ln/min (Air)

    • Analog model series D-6200

      • Minimum flow range      0.5 ... 10           ln/min (Air)
      • Maximum flow range     300 ... 6,000    ln/min (Air)
  • Mass flow measurement and control by means of the bypass principle

    • Analog model series D-5100

      • Minimum flow range      0.005 ... 0.1      ln/min (Air)
      • Maximum flow range     2.5 ... 50            ln/min (Air)
  • Both measurement principles work with no moving parts


  • Compact and rugged design


  • The instrument body is available in Aluminium as well as in stainless steel AISI 316L for corrosive gases


  • Additional characteristics of the D-6300 and D-6200 model series


    • Less sensitive to dirt


    • Less sensitive to humidity


    • No inlet pipe is needed

  • All mass flow meters and controllers are basically calibrated on air. If other gases or gas mixtures are used our powerful software determines a conversion factor for the desired equivalent of air (please refer to FLUIDAT® on the Net).


In general mass flow measurement is very sensitive to variations of the shape of the flow profile.

The MASS-STREAM® flow meters are designed for a consistent, fully developed flow profile in the metering section and they are thus less sensitive to changes of the inlet piping conditions.

In comparable instruments, which do not consist of such precautions for these effects of inlet piping conditions, some severe variations in the accuracy might occur.
