Notes concerning oxygen service
Î Devices intended to measure gaseous oxygen are labeled
Oxygen! Keep free of oil and grease!
These versions are cleaned and assembled under special conditions. When
replacing parts that come into contact with gaseous oxygen, e.g. range springs,
wear suitable gloves and make sure that the parts do not come into contact with oil
or grease.
Î Make sure that the dp cell and all SAMSON accessories only come into contact with
gaseous oxygen.
Î When returning devices for oxygen service for repair, the sender assumes full
responsibility that the devices are handled to meet all requirements stipulated by
VBG 62 or similar regulations until they are handed over to the manufacturer.
Otherwise, SAMSON does not accept any responsibility.
Risk of damage to the differential pressure and flow meter due to impermissible
negative pressure (vacuum) in the measuring chambers.
A negative pressure in the measuring chambers is not permissible during operation.
Î The following applies: operating pressure ≥ atmospheric pressure.
A vacuum in both measuring chambers for a brief period of time, e.g. to clean tanks,
is permissible.
Incorrect operation in cryogenic applications will damage the differential pressure
and flow meter and will lead to malfunction.
In cryogenic applications, the process medium circulates during measurement when
the equalizing valve is opened, causing the valve block to ice up.
Î During measurement, the equalizing valve must be closed and the shut-off valves
open.
