#### **Cons**
1. **High Initial Cost** The FS-201CV series is a premium instrument, and the specific model (with air calibration and USB/RS-232) may be more expensive than basic analog flow meters.
2. **Limited Built-in Gas Selection** The "AGD" designation suggests it is pre-calibrated for **air (AGD Air General Dry)**, meaning it may require recalibration for other gases, adding extra cost and time.
3. **Software Dependency** While the EL-Flow Select software is powerful, it requires a computer for full functionality, which may not be ideal for standalone field applications without power access.
4. **Sensitivity to Contaminants** Like all thermal mass flow meters, it can be affected by particulate matter or condensable vapors in the gas stream, potentially requiring additional filtration or maintenance.
5. **Calibration Requirements** For optimal accuracy, periodic recalibration is recommended, which may involve sending the device back to the manufacturer or performing in-house calibration (if equipped).
6. **Power Dependency** Requires a stable power source (typically 12 24 VDC), which may not be available in all environments.
7. **Learning Curve for Advanced Features** While user-friendly, mastering all functionalities (e.g., multi-gas calibration, scripting in EL-Flow Select) may require training, especially for non-technical users.
8. **Limited Mechanical Protection** The housing is not rated for harsh industrial environments (e.g., IP67), so additional protection may be needed for outdoor or dirty applications.
