How to Select the Right XY-TEK Flow Sensor: A Step‑by‑Step Approach

1. Identify the tubing type: flexible plastic (silicone, PVC, PE) → CG, CM, TGU; rigid plastic (PFA, PTFE, Nylon) → CPD, CS, BG; metal or large‑diameter → TPK, TPD.
2. Determine flow range: ultra‑low (<1 L/min) → TGU; low to medium (0‑80 L/min) → CG, CM, CPD, CS; high (up to 1000 L/min) → TPK, TPD.
3. Verify accuracy requirements: ±1% → TGU; ±2% → CPD, TPK, TPD, TH, SU; ±3% → CG, CM, CS.
4. Check certification needs: Confirm patent‑protected models (CPD, CS, CM, TGU) for added IP assurance. For medical applications, ensure biocompatible materials (CG, TH, SU).
5. Evaluate environment: temperature range (0‑60 °C for CG/CM/TGU vs. 0‑90 °C for CPD/CS/TPK/TPD).
