It is recommended to clean the flow sensors after each use according to procedure detailed in the MFS user guide. If possible, dedicate a discrete sensor for each different liquid to be measured. If this is not possible, plan a proper change of the media and include a cleaning step in-between.
To avoid clogging your sensors and having to buy another one, we advise performing a deep cleaning using Hellmanex on a regular basis. This protocol can be found in the MFS user guide.
