The automated cleaning configuration for the OilWatcher is applicable where the availability of an on-site operator is limited or when the water has high amount of oil or solids. A separate cleaning solution container is connected to the OilWatcher with included lines and fittings. The cleaning solution are changed at regular intervals of 1 week to 3 months, depending on the size of the container and the properties of the process water. The automatic cleaning is supplemented with manual cleaning using a tube brush when cleaning solution is changed.
