Flow Measurement (Option) - Ecom J2KNpro Tech Operating Instructions Manual

11.2. Flow measurement (option)

This measurement can be done with a
pitot tube. At first the pitot factor of the
pitot tube
(„Adjustments" / „Internal" / „Pitot
factor"). After connecting the pitot tube
to the instrument, 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 calculation
of the flow rate). After the pitot tube is
positioned in the flow channel, the
display shows the speed (m/s), the flow
3
rate (Nm /h)
pressure (Pa). 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).
