!
Note!
1. You can also perform calibration by means of the QUICK SETUP menu. → ä 140 ff, Table 5:
QUICK SETUP "Flow".
2. By means of the FLOW-MEAS. TYPE parameter, you can choose between the following flow
types:
– Volume operat. cond. (volume under operating conditions)
– Gas norm. cond. (norm volume under norm conditions in Europe: 1013.25 mbar and
273.15 K (0 °C))
– Gas std. cond. (standard volume under standard conditions in USA: 1013.25 mbar (14.7 psi)
and 288. 15 K (15 °C/59 °F))
–Mass
3. Depending on the flow type selected, you can choose between various units. You can also
specify a customer-specific unit.
See parameter descriptions for PRESS. ENG. UNIT (060) (→ ä 179), UNIT FLOW (391)
(→ ä 180), NORM FLOW UNIT (661) (→ ä 181), STD. FLOW UNIT (660) (→ ä 181) and
MASS FLOW UNIT (571) (→ ä 181).
4. In the lower measuring range, small flow quantities (creepages) can lead to large fluctuations
in the measured value. You can activate low flow cut-off via the LOW FLOW CUT-OFF (442)
parameter (→ ä 185).
