Because sump pumps can be washing down sumps, it means that the liquid can vary from water to slurry. There can be detergents that can create froth and foam. Anything that is intrusive will require constant cleaning and routine maintenance. This is an area that generally is paid very little attention to during the design phase, because of costs. Low-cost float balls, conductivity switches, admittance probes, and vibration switches, will work at the start, but require cleaning schedules to keep them operating. Because the liquid varies, the specific density will change so pressure transmitters are not the answer as well.
Lower frequency transmitters like the 20 kHz transmitter will handle the range, froth, foam, condensation, agitation, and splash conditions. They are self-cleaning and the extra cost of purchasing a non-intrusive level technology for your mining and minerals operation will pay in the longer term.
The 20 kHz transmitter can be operated off 2-wire comms Foundation FieldBus as well as ProfiBus PA.
