Sensors and Systems for combustion technology

Mass Flow Measurement Grid

  • Volume measurement of gaseous media in ducts, especially for comdustion air for firing applications
  • With a minimum of differential pressure loss, compared to the conventional technology
  • Short length of inlet- and outlet-stretch for laminar flow. Long air-ducts are not required anymore
  • Stainless steel material
  • Basic temperature range up to 400 °C
  • Free of maintenance for use in clean air application
  • Rectangular and circular grid versions are available
  • With increased dust particles loading, flushing back can be done (option)
  • Connection to the Differential Pressure Transmitter by impulse piping or on customer‘s request
Technical Data

The grids are made by specifications of the customers. Therefore the technical data can be indicated only generally. In the case of concrete offers, and/or supplies a data sheet made particularly for the appropriate grid is provided.
