Abstract
An automatic system for monitoring/controlling a variable of a machine or metalworking fluid system also achieves cleaning and optionally, a calibration check of the sensor of the variable. The system includes one or more sensors for variables such as pH, fluid concentration, conductivity, temperature and the like, a supply of a cleaning agent and associated valves and conduits for connecting the automatic system to a fluid to be measured. A cleaning cycle can be scheduled as necessary to clean and/or check calibration of the sensors and ensure accurate measurement of sensed variables. If desired, the data regarding the sensed variables may be utilized to perform corrective action in real time.
