    the Necessity of Selecting Rosemount 3051 Transimtter Pressure Guide Tube

    Date:2018-9-6 

    Definition of Pressure Guide Tube: also known as pulse tube, a direct contact with the process medium of the pipeline.


    Location principle of Rosemount 3051 transmitter and pressure guide tube


    1. Make the pilot as short as possible.
    2. Prevent deposition in the guide tube.
    3. Drain all the gas from the liquid branch.
    4. Make sure that the temperature of the two branches is the same.
    5. Keep the heads of the two branches of the guide tube equal.
    6. Avoid conditions that may cause the process fluid to freeze in the process flange.
    7. Use pressure ducts large enough to avoid friction and clogging.


    Material type:


    Selection principles:

    The physical properties, chemical properties and operating conditions of the medium to be measured shall be considered.

    1. 1Cr18Ni9Ti acid-resistant stainless steel pipe is selected as non-corrosive or weakly corrosive medium.
    2. Urea-grade stainless steel 316LN or other stainless steel tubes containing molybdenum are used for strong corrosion.
    3. Strong corrosion using plastic pipe.


    Characteristics:


    1. High intensity.
    2. Good tightness.
    3. To meet the process requirements.
    4. Meet the design requirements.


    Latest Information on Instrumentation:


    1. Scientific instruments to aid in cosmetic testing.
    2. Intelligent wearable devices may take the lead in the age of artificial intelligence.
    3. Deep ploughing dehumidifier industry Shanghai public useful 10 years to build a "national brand."
    4. Investment 10 million large-scale scientific research instrument national network management platform construction is perfect.
    5. For the first time, an acoustic imaging instrument has been used in Shanghai power grid to detect equipment defects.
