Problems solved by technology

[0002] At present, the multi-point thermometers used for temperature detection of storage tanks in the petroleum and chemical industries at home and abroad generally cannot output temperature data independently, but output temperature data through the matching liquid level gauge or tankside indicator, so that a multi-point thermometer system is configured. The price is very expensive, which limits the use of multi-point thermometers; even if some can output temperature data, they can only output the average temperature of all temperature points under the liquid and above the liquid. This temperature data is meaningless
