一、液面计零点高度差测量一般情况下,液面计标尺零点与罐底零点不在同一水平面上,所以需测量此高度差,在编制容量表时需对此高度差进行修正。1.液面计零点高度差罐外测量球罐液位计采用的是玻璃管、钢带等外测类液位计,需要罐外测量液位计零点高度差。具体测量方法 First, the liquid level gauge zero point height difference measurement Under normal circumstances, the liquid level gauge zero point and the tank bottom zero is not the same level, so the height difference to be measured in the preparation of the capacity meter to be amended when the height difference. 1. Liquid level gauge zero height difference tank measuring tank tank level gauge is used glass tube, strip and other external liquid level gauge, you need to measure the level gauge zero height difference.
