The level gauge board has both numeric and bargraph readouts for the voltage, oil, water and fuel level gauges. 该液位计局既有数字和光柱的电压读数，油，水和燃料水平测量仪。
Where greater coverage is required, multiple gauge glasses using either independent vessel connections or a standpipe shall be used. 在要求更大范围的地方，应使用利用独立导管连接或竖管的多层玻璃液位计。
