コリオリス質量流量計のキャリブレーション手順

コリオリの質量流量は、コリオリの力の原理に基づいて、流体質量流量を直接測定します。高精度（±0.1％-0.2％）、高速応答（<100ms), and strong stability. They are widely used in high-precision applications such as the chemical industry (e.g., measuring corrosive media) and the petroleum industry (crude oil trade settlement). Before calibration, confirm the instrument model (e.g., CMF100 series), range (0-50 t/h), and other parameters. Also, check the installation conditions (straight pipe length required: ≥10D) and the appearance of the instrument.

キャリブレーション中に、実際の動作条件（たとえば、原油に置き換えるディーゼル）、制御温度の変動（±1度）、および圧力変化（）と同様の媒体を使用します。<0.1 MPa), and strictly follow JJG1030-2020 regulations. During data processing, key metrics such as basic error (≤±0.15%) and repeatability (≤0.05%) must be calculated. If the results fail to meet the standards, investigate for sensor zero drift or signal processor failure.
