The flow meter is factory-tested, and some surface oil residue is normal and won't affect its functionality. During installation, ensure the interface is tight. Use a gasket or tape to enhance the seal. If the flow meter doesn't turn, it may be due to rust caused by water exposure or foreign objects blocking the turntable. Install a pre-filter to prevent this issue.
