Cleaning the turbine flowmeter
It is necessary to disinfect periodically the turbine for sanitary measures or/and for the
correct device function.
As disinfecting solution it is suggested Sodium hypochlorite 5% (bleach).
The disinfecting procedure is easy and may be effected every time the user needs,
keeping attention to some precautions:
1. Take out the turbine.
2. Dip it in a disinfectant solution (non alcoholic based) for about 1 hour.
3. Rinse the turbine in a vessel, filled of clean water, shaking gently to remove the
disinfectant (do not clean the turbine by putting it under running water!).
4. Let it dry to air.
5. After cleaning the turbine, check if the turbine propeller rotates freely even with a
low speed air flow.
6. Connect the turbine to the reader.
Precautions during the cleaning of the turbine
1. Do not expose the turbine to high heat and do not put it under running water.
2. Do not ever dip the optoelectronic reader in any kind of solution, the liquid
infiltration would damage the internal circuit.
3. Do not use alcoholic solutions to clean the turbine.
