Note!
1.
You can also perform calibration by means of the QUICK SETUP menu.
See Page 52 ff,
Table 5: QUICK SETUP menu.
2.
Using the FLOW-MEAS. TYPE parameter, you can choose between the following flow types:
– Volume p. 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 description for PRESS. ENG. UNIT (
Page 92), UNIT FLOW (
Page 93),
NORM FLOW UNIT (
Page 93), STD. FLOW UNIT (
Page 94) and MASS FLOW UNIT
(
Page 94).
4.
A flow value or a pressure value is assigned to both the lower and upper current value with
the SET LRV (
Page 99) and SET URV (
Page 100) parameters.
Description
1
Before configuring the device for your application, the
pressure piping must be cleaned and the device filled
with fluid. See Operating Instructions BA00270P,
Section 6.4.1.
