Rod glass thermometer
Thread Content
In a design project I was working on, the plant’s metering department required the use of rod-type glass thermometers in front of the flow meters. I would like to know what type of measuring nozzle should be used for the glass thermometers in the pipelines
Why isn’t anyone answering? ? ? Waiting online! ! !
Why stay? A flow meter with temperature and pressure compensation will suffice!
Measurement requires knowing the high-precision temperature value at that location
The type of thermometer with threads at the bottom of the stem is a set in which the nut is welded to the pipe; I think I’ve seen that before.
Rod-type thermometers used for high-precision temperature measurement cannot achieve the required precision, as the measurement port designed in such instruments necessarily has a sleeve, and the temperature inside this sleeve does not stay in sync with the temperature inside the pipe (unless the temperature inside the pipe remains constant). It is recommended to use high-precision temperature transmitters based on thermal resistors. Your measurement department is probably used for some calibration system, right?
