How is the insertion depth of the thermometer determined or calculated? 1. How is the insertion depth of a thermometer on a pipeline calculated? Is threading or flanges a better connection method? 2. How is the insertion depth of the thermometer on the equipment calculated? Is threading or flanges a better connection method? What impact does a greater or lesser insertion depth have on measurements? It would be great to have some guidelines or standards for this, thank you!
Take a look at the \"Code for Installation Design of Petrochemical Instruments\" SH/T 3104-2013
There is no calculation involved; it’s mainly about measuring the actual temperature.
Flange-type ones are generally better
The temperature sensing point is at 2/3 of the pipeline. The connection method is related to the operating temperature and pressure
The equipment depends on specific requirements. Is it a storage tank, a reactor, or some other equipment? Pipelines are usually 1/3, right, not exceeding 200?
The insertion depth of the thermometer must be determined based on the size of the pipe; as for the equipment, it goes without saying that in the case of devices with agitators, the thermometer must not come into contact with the agitator blades. The flange connection method is more convenient for disassembly
It’s enough to be able to measure the true temperature of the liquid; no complicated calculations are needed
