Beschreibung
Zusammenfassung:	A method and apparatus for monitoring usage of liquids of high value or sensitive nature which are applied in repeated small controlled volumes are provided by monitoring and recording parameters including the number of applications, purging, priming and cleaning steps and the usage of liquid supply and circulation pumps. The monitored parameters present a record of the total liquid usage. The recorded usage of the liquid pumps can be cross-checked with the volumes indicated by the other parameters so as to highlight any disagreement between the respective indications of total liquid volumes employed, thereby alerting the user to possible operating problems and permitting prompt remedial action to be taken.
