The plan was calibrated on some digital level meter and achieved the satisfactory results.
该方案已在几种数字电平表上实验并取得满意的结果。
Such a level sensor is capable of continuously measuring helium level within 60cm high, helium level is displayed directly on a digital meter.
用它能连续测量60厘米高度范围内的液面变化，液面高度由数字表头直接显示出来。
Constant flow rate manually adjustable, proportional flow rate according to a digital input signal (from water meter), Power-ON led indicator and level control input. The two different modes are.
比例调节，可根据数字信号（比如水表发出的脉冲信号）来调节流量的比例，带有电源指示和液位探头接口，可直接连接液位探头控制计量泵启动或停止。
