This screen displays date and hour of the last calibration, the pressure and temperature values to
which flow-rate was calibrated, and flow-rate parameters with the calculated values of the new F
coefficient.

Pressures fields :

P1 field : pressure value upstream the critical orifice,

P2 field: pressure value downstream the critical orifice,

Atm. field : atmospheric pressure measurement.
The atmospheric pressure measurement is performed continuously.

Temperatures fields :

Filter field : temperature at level filter,

Atm. field : External temperature measured by the meteo sensor (if the meteo sensor option is
available).

Flow-rate fields:

Reference field : the setting value of flow is set to 1 m

/h, it does not vary.

Previous F coef. field : the value of the previous factor is used to calculate the new factor.

Span field : reference flow

New F coef. field : obtained by calculation :
