SUMMARY
The volume ratio between the bulb and the tube in a bulb thermometer is not fixed and varies based on design requirements. For optimal sensitivity, the bulb should be maximized while the tube should be minimized in diameter. This balance is influenced by the temperature range the thermometer is intended to measure. Specific designs may dictate different ratios to achieve desired performance characteristics.
