Measurement of fish oil

The challenge:

A customer was looking for a level switch for 6 tanks with fish oil. The tanks are 11 meters high and approx. 3 meters in diameter. The fish oil forms a foamy layer during filling. Danova has provided a radar solution for continuous level measurement, but the customer wanted extra security against overfilling. Several other level guards had been tried, but all failed because of the foam formed during the filling of the silos.

The solution:

For many years, Danova has had experience with capacitive level switches. We were convinced that RFnivo RF3100 was the right solution. The customer placed one in each of the 6 tanks, and was impressed with the simple installation, but especially the auto calibration. RFnivo accurately detects the fish oil and ignores the foam layer that is formed. RF level is connected to the customer’s PLC so the “time delay” that can be activated in the quick start menu is not necessary. RFnivo has worked from day 1, without any readjustment or problems. Of course, the customer is happy to have finally found a solution to the “foam” problem.
