Maintenance
Cleaning
This device requires minimal maintenance. If necessary, the outside of
the device can be cleaned with a soft, dry cloth. Avoid excess moisture
or solvents.
The primary cause of damage and/or long-term inaccuracy in these
devices is contamination and/or corrosion damage. Gases and liquids
should be filtered for particulates or biological materials that may grow
in the device. When removing these units from the line for any extended
period of time, make an effort to remove all of the gas or liquid from the
device, as deposits of calcium, soluble minerals, or other particulates can
affect the accuracy of the device.
!
If you suspect that debris or other foreign material has
entered your device, do not take apart the flow body to
clean it, as this will negate its NIST-traceable calibration.
Please contact us (see
) for cleaning.
Recalibration
The recommended period for recalibration is once every year. A label
located on the back of the device lists the most recent calibration date. This
date is also stored by your pressure controller and is visible by selecting
