The smallest components can make the biggest difference.
A single sensor can determine the efficiency of an entire wastewater treatment process.
Inclination sensors from ifm played an important part in this biological wastewater treatment plant. This sensor allowed the PLC to calculate the level of the lagoon by measuring the angle of the rising and falling pontoons.
Why do we need to know the lagoon level in this plant design? The lagoon level tells the PLC logic if enough new water has come into the plant. It dictates if the SBR (Sequence batch reactor) downstream can or cannot initiate a settle and decant process of the treated effluent.

So we’re a big fan of ifm instruments. To measure the level of the water in this lagoon, we’ve got a JN2201
mounted to the side of this platform. So as the water level rises and falls with these pontoons, that changes the angle, that goes back to the PLC , does a little bit of computing, and then spits out a level.
An instrument like this really reduces the operator time for cleaning sensors, worrying about lenses on optical devices. This thing’s mechanical, it’s literally measuring an angle and then the PLC does the rest.
