导向管安装确认项:
Guide Pipe Installation Confirmation Item:
导向柱要求垂直,公差需保持在规定要求内;可通过重锤或其他光学仪器测量验证
The guide column should be vertical and the tolerance should be kept within the specified requirements. It can be verified by measuring with a heavy hammer or other optical instruments.
管子本身需垂直;
The pipe itself needs to be vertical.
用以安装伺服液位计的法兰水平度应保持在 0.5 °以内;
The flange level used to install the servo level gauge should be kept within 0.5 degrees.
导向柱内侧需要光滑,没有焊缝、焊渣、毛刺等有可能妨碍浮子移动的障碍物;
The inner side of the guide column needs to be smooth, and there are no obstacles such as welding seam, welding slag and burr that may hinder the float movement.
导向柱的平衡开孔应足够高以便液位计有效地测量,且所有开孔上的毛刺被清理干净;
The balanced opening of the guide column should be high enough to be effectively measured by a liquid level gauge and all the pores on the opening should be cleaned.
转换接头和导向管的中心应和浮子移动的方向一致。
The center of the transfer joint and guide pipe should be in accordance with the direction of the float movement.
可把此6项做出成表,便于安装完成后确定留底。
These six items can be tabulated to facilitate the determination of the bottom after installation.

Servo Level Meter Installation
安装液位计的法兰必须尽可能水平,水平度应好于0.5度,否则可能造成测量误差;
The flange of the level gauge must be as horizontal as possible, and the level should be better than 0.5 degrees, otherwise the measurement error may be caused.
检查电源选择器选择的电压与液位计铭牌以及现场所提供的电压是否一致;
Check that the voltage selected by the power selector is consistent with the nameplate of the level meter and the voltage provided by the site.
