Standard aerodynamic measuring installation WK845050-g

Developed and operated since 2015

Composition:

  • compressor installation;
  • collector;
  • air ducts;
  • rotary unions;
  • honeycombs;
  • pressure regulator;
  • diffuser;
  • gauging nozzle;
  • thermoelectric anemometer with flow calculation system 8455-300-1;
  • pressure tube Pitot with differential pressure transducers.

Metrological characteristics:

Installation is designed for tests, calibration, attestation and verification of anemometer (thermoanemometers, vane anemometers, cup anemometers, pressure pipes) of different types within the range of reproduced air flow speeds from 0,1 m/s to 40 m/s and has the following metrological characteristics:

  • Limit of permissible absolute error of speed reproduction:
  • when using thermoelectric anemometer 8455-300-1:
  • within the range from 0,1 to 0,5 m/c Δ = ±(0,009 + 0,009·V),
  • within the range from 0.5 incl. to 1,0 m/c Δ = ±(0.004 + 0,01·V),
  • when using pressure tube Pitot with differential pressure transducers:
  • within the range from 1 incl. to 140 m/c Δ = ±(0,004 + 0,009·V),
  • Diameter of output section of gauging nozzle: 450 mm

Traceability – DKD (Германия)

Scope of application:

  • instrument making;
