Operation with pump
Operation with pump
Observe the following when performing measurements using the pump
 Perform visual inspection of the probe, if necessary.
 Wait for the flushing time to end.
Flush the Dräger sampling hose or Dräger probes prior to each measurement with
the air sample to be measured.
The flushing phase is necessary to minimize or eliminate any effects associated with
the use of a sampling hose or a probe, e.g. memory effects, dead volume.
The duration of the flushing phase depends on factors such as type and concentration
of the gas or vapour to be measured, material, length, diameter and age of the
sampling hose or probe. As a rule of thumb, a typical flushing time of 3 seconds per
metre can be assumed for a sampling hose (factory-new, dry, clean). This flushing time
applies in addition to the sensor response time (see instructions for use of the gas
detector used).
Example:
The flushing time for a 10 m hose is approx. 30 seconds. The sensor response time is
approx. 60 seconds in addition. The overall time before reading the gas detector
therefore is approx. 90 seconds.
The flow alarm is delayed by 10 to 30 seconds, depending on the hose length.
