Funnel Adapter for Anemometer Eurochron WS4003

With this adapter it is possible to attach a funnel to the WS4003 anemometer. I have designed this funnel adapter to measure my air conditioning system at home.

The adapter can be printed easily without support and with snappers not depending on layer adhesion.

Needed material:

• Anemometer Eurochron WS4003
• any kind of box having a plane area of 60mm diameter
• 2x screws 2.2 x 4.5 mm
• 4x screws 2.2 x 6.5 mm or longer, depending on the funnel thickness

Assembly:

• Insert the 2 snappers into the baseplate. They are mounted by a screw but for a reliable fixation they should be additionally glued.
• Cut a hole with a diameter of 28mm into the box. You can use the baseplate or backplate as a caliber.
• Fix the box by screwing together backplane with baseplane.
• Snap in the anemometer when you want to measure. After measuring you can remove it.

Usage:

• Put the box over the air valve and measure the air flow.
• You can make an estimation of the air flow:
  air flow:f = a* v
  size of free tunnel area:
  a = ra2 - ri2 - (3 9 mm 1.5 mm) = 412 mm2
• In short:f [m3/h] = v [m/s]* 1.48
