Resume:
|
- 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
