Burkert Type S039 - Manual (Page 8)

ENGLISH ENGLISH
flow rate controller 8039
3 technical data
General features
Pipe diameter DN6 to DN50 (1/4’’ to 2’’); determine the appropriate diameter using the
flow rate-velocity-DN diagrams (see Annex)
Fluid temperature max. 100 °C
Fluid pressure depends on the S039 fitting (see the corresponding fitting manual)
Fluid viscosity max. 300 cSt
Rate of solid particles max. 1%
Measuring range 0,3 m/s to 10 m/s ( 1.0 to 32 fps), 0.3 m/s (1.0 fps) corrresponds to a flow rate of 0,5 l/min
( 0.2 gpm) in a DN6 (1/4’’) fitting.
Accuracy ±1 % of the full scale*, with calibration on site or using the teach-in function
± (1 % of the full scale* + 3% of the measured value), with standard K factor
Linearity ± 0.5 % of the full scale*
Repeatability 0.4% of the measured value
Measuring element paddle-wheel of the S039 fitting
Protection rating (housing) IP 65, cable plugs being plugged-in and tightened
* Full scale = 10 m/s
