Flow Measurement (Option) - Ecom EN2 Operating Instructions Manual

Re-connect the draught tubing. The
display shows the exact measurement
value which can be stored while pressing
<Record> and added to those results
previous stored in the intermediate
memory. The stored value is shown on
the display. Press <ESC> to exit the
draught measurement menu.

8.5. Flow measurement (option)

This measurement can be done with a pitot
tube. At first the pitot factor of the pitot tube
must be entered („Adjustments" /
„Internal" / „Pitot factor"). After
connecting the pitot tube to the
instrumentment, the zero point of the
sensor can be set with <F4>. With <F1>
the cross section of the flow channel can
be entered (needed for colculation of the
flow rate). After the pitot tube iss positioned
in the flow channel, the display shows the
speed (m/s) and the flow rate (Nm3/h). If
the value indicated is stable, press
<Record> to store the value in the
intermediate memory. If a printout of the
values should occur simultaneously to the
recording in the intermediate memory,
press <F2> (the complete content of the
intermediate memory will be printed out).
