| Abstract: | With constant improvement of automation of air separation plant and ceaseless demand on load-variable operation,the correctness of measuring the low-temperature flowrate,the important parameter reflecting operation load of air separation plant,becomes increasingly important,and the key is how to improve instrument's detection precision,decrease measurement error,and correctly select and use flowmeter.Here,the measurement principles of low-temperature liquid flowmeters for air separation plant are analyzed and compared,and the selection principle and the factors to be considered in design and installation are detailed in combination with application cases. |
