How to purge the pressure guiding tube of an oxygen pipeline flow meter?
Thread Content
When purging the oxygen pipeline, in order to prevent damage to the flow meter during the purge process, it is necessary to remove it and replace it with a short circuit; the flow meter can be reinstalled only after the purge is complete. So, when can the pressure guiding tube of the flow meter be purged?
The pressure guiding tube of the flowmeter is cleaned and degreased before installation, and no purging is required. After the pipeline under test has been completely cleaned, install the flow orifice plate and pressure guide tubes. For reference.
