Draft Measurement - Ecom -D Operating Instructions Manual

Re-connect the draft tubing. The display shows the
exact measurement value which can be stored by
pressing <Record> and added to those results pre-
vious stored in the intermediate memory. The stored
value is shown on the display. Press <ESC> to exit
the draft measurement menu.
8.3. Flow measurement (option)
This measurement can be done with a pitot tube.
First, the pitot factor of the pitot tube must be en-
tered by going to <Adjustments> / <Internal> /
<Pitot factor>). After connecting the pitot tube to
the analyzer, the zero point of the sensor can be set
with <F4>. Enter the cross section of the flow chan-
nel with <F1>. This is needed for the calculation of
the flow rate. After the pitot tube is positioned in the
flow channel, the display shows the speed (m/s) and
the flow rate (Nm3/h). If the value is stable, press
<Record> to store the value in the intermediate
memory. If a printout of the values is needed during
the recording to the intermediate memory, press
<F2>. The complete content of the intermediate
memory will be printed out.
