“heavy duty” Type RG 20 made by pvt

The universal flow sensor for moderate to heavily soiled and/or steam saturated smoke gas, raw gas, and process gas. 

 

Previously used Venturi nozzles have following disadvantages:

  • relatively poor accuracy especially for high nominal width
  • long intake lines, which are rarely available at high nominal width
  • relatively high constant pressure loss (= energy loss) which is no longer accountable due to today‘s energy costs
  • limited usability in heavily soiled and/or steam saturated media
  • substantial and expensive installation costs

 

With type RG 20 the drawbacks mentioned above could be totally eliminated. RG 20 are produced for all applications in different variations, adapted to specific requirements. 

 

Advantages of type RG 20:

  • extremely insensitive to dust, dirt, slime, and humidity
  • high accuracy even without intake lines
  • virtually no constant pressure loss / no energy loss
  • low installation costs, no hinge bracket required
  • for pipe width up to 18000 mm
  • available in almost every material, acid-proof and resistant up to 1200°C
  • size of drillings for working pressure = 18 mm
  • no vibration crackings caused by vortex formation

Following examples prove applications for which type RG 20 is working trouble-free for years:

  • Raw gas in front of filter in power plants / MVAs (waste burning plants)
  • Raw gas in front of cyclone in cement mills
  • Stack Gas, blast furnace gas, wind-gas in steel mills
  • Smoke gas in power plants / MVAs
  • Carbon- and flint mill air
  • Heavily soiled and steam saturated smoke- / process gas
  • Slimy process gas
  • Primary air, secondary air, combustion air, recirculated flue gas
  • The applications mentioned above are partially without intake lines and directly after arches

 

Due to the long and oval shape of RG 20 there is no vibration cracking or vortex formation. Hinge brackets are totally unnecessary. 

 

RG 20 with integrated pressure sensor and thermo couple. You can see both wash-up connectors and screws for the pig orifices, which are located at the sensor‘s tip.. 


Although wash-up and pig connectors are standard, in practice it is hardly necessary to flush the RG 20. Our automatic flushing device is needed very rarely.
