Spare Parts Selection Recommendations

  1. Confirm the flowmeter model and communication protocol (HART, PROFIBUS PA, or Foundation Fieldbus).
  2. Select intrinsically safe (Exi) or flameproof (Exd) spare parts according to hazardous area classification.
  3. Verify cable gland thread specifications (M20x1.5, NPT 1/2", G 1/2", or PG13.5).
  4. For remote installation, choose 10m or 30m cables based on distance, and confirm whether explosion-proof armored cables are required.
  5. Provide the complete order number when ordering to avoid downtime due to specification mismatch.

Note: Some spare part order numbers appear repeatedly (e.g., 50103527, 50103658, 50098036, etc.), possibly corresponding to different packaging quantities or application scenarios. Please confirm specific packaging specifications with the supplier before purchasing.
