The issue of thermometer insertion depth in spherical tanks
Thread Content
Is there a maximum depth for inserting the thermometer in a spherical tank? The SH3005 standard only states that the distance from the inner wall must be no less than 150 mm Is there anyone who can give an answer? ! !
1. Regulatory requirements: A. SHT 3007-2014 Code for Design of Storage Areas in Petrochemical Processing and Transportation Systems, 5.4.6; B. SHT 3184-2017 Code for Design of Automation Systems in Petrochemical Storage Areas, 4.2.1.4, 4.2.1.6. 2. Practical experience: For spherical tanks, a temperature sensor is generally installed at the bottom, with an insertion depth of 350 mm； Servo-driven multi-point temperature measurement is used for tank capacity calculation.
These two specifications mainly address the installation height of thermometers on storage tanks, with little mention of the insertion depth
