[0002] Styrene tar is a by-product of styrene production. When pumping ethylene tar into tanks for transportation, a mass flow meter is required for metering and control. Since the coke in styrene tar is easy to precipitate and form hard coke blocks, which are difficult to remove, timely treatment is required after precipitation and agglomeration occur on the inner wall of the mass flow meter, otherwise it will greatly affect the efficiency and accuracy of the measurement. In the existing technology, the cleaning of tar precipitation and agglomeration is mostly done by flushing with a treatment agent. Since sufficient contact reaction is required, the flow meter is mostly disassembled and cleaned separately, which makes the operation cumbersome and reduces the efficiency of the operation. If the entire pipeline is circulated and cleaned, the cleaning cost will increase significantly, and it is extremely inconvenient to use. Summary of the Invention
