Incoming material inspection
-
In-process inspection during assembly
-
Final functional testing of each meter
-
Long-term stability and repeatability testing
A high-quality factory should perform 100% testing before shipment, not random sampling.
Calibration capabilities are especially critical
Ask whether the factory has:
-
In-house mass flow calibration systems
-
Traceability to national or international standards
-
Multi-point calibration across the full flow range
-
Zero stability and density accuracy verification
