A general rule is that the tip should be at least 1/3 to 2/3 into the fluid stream for accurate readings.

4. Process Connection Type

The connection between the thermowell and the process system must be secure and suitable for the environment:

·         Threaded Thermowell: Easy to install and remove; used in lower-pressure systems.

·         Flanged Thermowell: Provides a more secure connection, often used in high-pressure applications.

·         Weld-In Thermowell: Offers a permanent, leak-proof connection for critical applications.

5. Velocity and Pressure Considerations

High flow rates can create vibrations that may cause thermowell failure. It is important to perform a wake frequency calculation to ensure the thermowell can withstand process conditions without breaking. In high-pressure environments, reinforced or shortened thermowells may be required.

Installation Best Practices

Proper installation is key to maximizing the efficiency and longevity of a thermowell. Follow these best practices:

·         Ensure Proper Length: Avoid excessive or insufficient insertion.
