四、儀表選型：
◆量程范圍確認
    一般工業用防爆型流量計被測介質流速以2～4m/s為宜，在特殊情況下，zui低流速應不小于0.2m/s，zui高應不大于8m/s。若介質中含有固體顆粒，常用流速應小于3m/s，防止襯里和電極的過分磨擦；對于粘滯流體，流速可選擇大于2m/s，較大的流速有助于自動消除電極上附著的粘滯物的作用，有利于提高測量精度。
  在量程Q已確定的條件下，即可根據上述流速V的范圍決定流量計口徑D的大小，其值由下式計算：
    Q=πD2V/4
    Q:流量（㎡/h） D:管道內徑 V：流速（m/h）
 防腐型電磁流量計量程Q應大于預計zui大流量值，而正常的流量值以稍大于流量計滿量程刻度的50為宜。
