Aircone hoods are the quick and accurate method to maximise the usefulness of your Airflow / TSI 100mm (4") rotating vane anemometer. For a very modest investment, you can double the capability of your velocity instrument into an air volume flow meter as well.
Commissioning and balancing of air volume flow is immediately possible at grilles, diffusers and air valves. The hoods are equally suitable for measuring ventilation flow rates for both extract and supply air.
Manufactured in hard wear ABS for the rigours of on-site use. All sizes are extremely lightweight allowing one man operation for long periods and one handed testing up ladders etc. when used with appropriate anemometer.
Using the Aircone is simplicity itself. Just clip your 100mm (4") rotating vane into the collar of the hood with the sensor pointed into the direction of flow, i.e. for extract or supply. Fit the hood over the inlet / outlet to be balanced and hold in place so that the flange creates a seal with the overall dimensions of the grille or diffuser under test.
Where grilles are larger than the size of the hood it is suggested that the area is divided into equal areas, avoiding overlapping where possible, then a series of readings are taken, adding together and averaged to calculate total volume flow.
FEATURES
• Aerodynamic design for minimal resistance.
• Direct reading of volume flow rate with instruments having area input facility.
• Volume flow curves in m³/sec and cfm for velocity measuring instruments.
• Self sealing for leak tight readings.
• Tough ABS to take knocks on-site.
• Compatible with all Airflow / TSI 100mm (diameter) vanes.
BENEFITS
• Converts 100mm vane anemometer into flow meter.

FREQUENTLY ASKED QUESTIONS
Q Can I use any 100mm vane anemometer with the Aircone hood ?
A Yes but please check with our sales department to check compatibility. Also the equipment must be calibrated for volume flow so that the errors in the complete system are known.
Q Will the Aircone hood put a back pressure on the system being tested and this influence the results ?
A The instrumentation can create a small back pressure on some systems, but as they are often used as proportional balancing tools this effect is the same on each part of the ventilation system being checked. Hence the overall balancing ratio's remain constant so any system back pressue has a negligible effect on the results.
NOTE: If required. 100mm (4") vane anemometers must be order separately. All calibrations must be conducted in conjunction with an anememoter.
