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
