摘要：
The lubricant level within a reservoir is difficult to monitor, leading to the reservoir being refilled more often than necessary to ensure that the reservoir always contains lubricant. A lubricant level sensing system is connected to and monitors various aspects of the pump assembly that draws lubricant from the reservoir. The pump assembly displaces a known volume of lubricant with each pump stroke. A lubricant-level estimator calculates an estimated lubricant level remaining in the reservoir based on a stroke-count value as sensed from the pump assembly and on a reference value stored in a memory. The estimated lubricant level provides the lubricant remaining and the rate of usage such that maintenance can be scheduled ahead of time to prevent the reservoir running dry.
摘要（中）：
储油罐内的润滑油液位难以监测，导致储油罐重新充满的次数超过必要量，以确保储油罐始终含有润滑油。 润滑剂液位传感系统连接到并监测泵组件的各个方面，其从储液器吸取润滑剂。 泵组件在每次泵冲程时都会排出已知体积的润滑油。 润滑剂水平估计器基于从泵组件感测到的冲程计数值和存储在存储器中的参考值计算存储器中剩余的估计润滑剂水平。 估计的润滑剂水平提供剩余的润滑剂和使用率，从而可以提前安排维护，以防止油藏干涸。
