The universal flow sensor for moderately to extremely contaminated and/or steam-saturated flue, raw and process gases.
TÜV-approved and certified by UAL according to TA- Luft, 13th and 17th BImSchV
Previously used Venturi nozzles have big disadvantages:
- insufficient accuracy
- long inlet sections are required, which are rarely available for large nominal diameters
- Relatively high permanent pressure losses (energy losses), which are no longer justifiable at today's energy costs.
- solely conditionally applicable with heavily soiled and/or steam saturated media
- substantial assembly efforts associated with high costs
With the Poettersonde® type RG 20 the above mentioned disadvantages were completely eliminated. Poettersonden® type RG 20 are built for all applications in different variations, adapted to the respective requirements.
Advantages Poettersonde® type RG 20:
- extremely resistant to dust, dirt, slime, moisture
- high accuracy even with non-existent inlet distances
- practically no permanent pressure drop/energy loss
- low installation costs, no counter bearing required
- for pipe diameters up to 18,000 mm
- available in almost any construction material, acid-resistant and heat-resistant up to 1,200 °C
- Size of the differential pressure holes = 14 mm
- no vibration fractures due to vortex formation
The following examples demonstrate applications in which Poettersonden® type RG 20 have already proven themselves over several years of trouble-free operation:
- Raw gas before filter in power plants/MVAs
- Raw gas before cyclone in cement works
- Blast furnace gas, blast furnace gas, wind gas in steelworks
- Flue gases in power plants/MVAs
- Coal and stone mill air
- heavily soiled and water vapour saturated smoke/process gases
- mucilaginous process gases
- Primary, secondary, combustion air, rezi (recirculation).
The Applications mentioned above are partly without inlet sections and directly after bends. Due to the long oval design of the Poettersonde® type RG 20, there are no vibration fractures due to vortex formation. Counter bearings are not required.
