在石油化工企业中,QBC差压变送器是测量流量、液面的主要仪表,其大部分技术指标可以经过调校来达到,但由于仪器的加工精度和安装方法等原因,会使静压误差这项指标偏大,这就需要靠合适的调整方法来消除它。 In the petrochemical industry, QBC differential pressure transmitter is to measure the flow, the main instrument of the liquid level, most of its technical indicators can be adjusted to achieve, but due to the processing accuracy of the instrument and installation methods and other reasons, will make static pressure This indicator is too large error, which requires appropriate adjustment methods to eliminate it.
