New nozzle to measure ventilation air flows in grids of 600x150 mm maximum. Adapted to the testo 405i meter (Surely you can use other probes).
The nozzle is divided into 5 parts that must be glued together.
The layer height is 0.25mm, in general. In the con_entrada.stl piece, I have configured two zones with variable layer height (reduced to 0,15 mm) to improve the geometry.
In the “central.stl” and "lateral.stl" pieces I have added an auxiliary geometry to avoid the possible warping. Must be cut.
A plastic cable gland (thread size PG11) can be attached to fix the probe.
A self-adhesive rubber joint (EVA, Neoprene or similar) can be placed to adjust the nozzle to the grid.
The maximum flow that can be measured (30 m/s) is limited by the probe (testo 405i in this case). This probe also measures air temperature in the range of -20 to +60ºC
The nozzle is designed to be used in the ventilation of homes, with relatively low flow rates.
NOTE: The measurement result should be considered as a reference. I have not yet performed any verification of this nozzle for different grates in the laboratory.
