Abstract
A liquid feeding pump operation monitor includes: a liquid gauge that measures a remaining amount of a liquid to be fed by a liquid feeding pump; and an operation detector configured to detect a reduction of the remaining amount, which is measured by the liquid gauge, of the liquid to be fed, and to detect an operation of the liquid feeding pump based on the detection of the reduction.
Claims8
An analysis system comprising:
- an analysis device that performs analysis using liquid flow, the analysis device including a liquid feeding pump for feeding liquid from a container to provide the liquid flow, the container containing a liquid for the analysis;
- a liquid gauge that measures a remaining amount of the liquid in the container;
- an operation detector configured to detect a reduction of the remaining amount, which is measured by the liquid gauge, of the liquid to be fed, and to detect an operation of the liquid feeding pump based on the detection of the reduction;
- and
- an operating time calculator configured to calculate an operating time of the liquid feeding pump by adding up a time during which the operation of the liquid feeding pump is detected by the operation detector.
