The AutoFlush can be used with Pi’s pH, ORP, free chlorine, total chlorine, ozone and chlorine dioxide sensors (or a combination of sensors) and consists of a large flow cell that automatically empties on a user selectable time basis. The signal from the sensor is held and the whole flow cell including the sensor(s) is flushed with clean water. For the original customer this meant a new pH sensor after 18 months rather than sooner, resulting in a significant improvement in process control and a very significant saving in pH sensors. Since then many customers have taken advantage of the AutoFlush and it is installed around the world in paper mills, food factories and other plant where keeping the sensors clean enhances their performance.
The AutoFlush by Process Instruments extends the life of sensors and drastically reduces maintenance procedures, and therefore cost, by automatically cleaning the installed sensors at intervals chosen by the user.
The AutoFlush cell requires zero maintenance, other than the obligatory sensor maintenance (consumables). The AutoFlush cell is cleaned whilst the cleaning cycle is active.

Whatever the process being monitored is, there is often something in the sample water capable of fouling a sensor, and therefore causing erroneous results. The obvious solution to this problem is to clean the sensor, but how regular should inspection and cleaning programs be for each piece of instrumentation? Too regular and the inspection and cleaning regime is time consuming and unnecessarily costly. Not often enough and the instrumentation will give false results and probably fail prematurely.
Pi’s AutoClean and AutoFlush systems can give trouble free and fouling free functioning of sensors for weeks, if not months, at a time.
If using air to clean a DO sensor the system can also automatically verify that the sensor is still responding correctly, removing any need to remove the sensor from the sample for months at a time.
