Cleaning and Flushing
If there is a buildup of deposits or particles from the measured gases it may
be necessary to clean
or flush
the unit. This should be done by flowing
clean, particle free air (or Nitrogen) through the unit at a flow rate, pressure
and temperature within the specifications of the unit. If necessary, flow may
be reversed to assist flushing.
CAUTION:
Do not flow a high pressure gas through the sensor.
A burst of high pressure gas may cause the turbine wheel sensor
to be damaged. Always flow gas at a pressure and flow rate
within the specifications of the unit.
