Table 1. Molbloc-L Pressure Dependent Calibration Types - Fluke MOLBOX RFM Operation And Maintenance Manual

The molbloc-L pressure dependent calibration types are summarized in Table 1.

Table 1. molbloc-L Pressure Dependent Calibration Types

CALIBRATION TYPE
Full mod, 200 to 325 kPa absolute
low pressure (29 to 48 psia)
upstream of molbloc
Full mod, 325 to 525 kPa absolute
(48 to 76 psia)
high pressure
upstream of molbloc
Atmospheric pressure (95 to
Downstream
105 kPa, 13.8 to 15.2 psia)
downstream of molbloc
Any specified single molbloc
Single P,
upstream pressure between
low pressure
200 and 325 kPa absolute (29
(non-N2 gases only)
to 48 psia)
Any specified single molbloc
Single P,
upstream pressure between
high pressure
325 and 525 kPa absolute (48
(non-N2 gases only)
to 76 psia)
Differential pressure values are nominal and may vary by up to 15 % with the
actual molbloc used.
