ABSTRACT

At present, inaccurate flow measurement often exists in steam flow meter of steam supply network under variable operating conditions. Therefore, this article takes isa 1932 nozzle flowmeter as the research object, establishes its measurement error mathematical model, studies the influences of steam supply parameters on its flow measurement error under variable operating conditions, and analyses the reasons for these influences. the results show that in the area of small flow (less than 0.3kg/s), the steam supply flow has a great influence on the flow measurement, the flow measurement error of isa 1932 nozzle flowmeter increases by 0.66% for every 0.1 kg/s reduction of steam supply flow. While in the area of large flow (greater than 10kg/s), the steam supply flow has little influence on the flow measurement, and the flow measurement error of isa 1932 nozzle flowmeter approaches zero. Compared with the steam supply flow, the steam supply pressure and temperature have a greater impact on the isa 1932 nozzle flowmeter. In the area where the steam supply pressure is small (less than 0.8mpa), the flow measurement error of isa nozzle decreases by about 0.02% for every 0.1mpa increase in the steam supply pressure. Under design conditions, the flow measurement error of isa nozzles increases by about 0.03% for every 10 ℃ increase in steam supply temperature.
