Follow up on the flow meter status.

- connectors disassembled, cleaned, contact to the pin opened, soldered

- ordered 2 connector assemblies to replace corroded contacts

- flow meters mounted on the plate, tested, insulated

- insulation boxes sealed, purging lines with dry air installed

These actions will ensure flow meter protection against humidity.
