Fouling is a complex (sometime partially known and described) phenomenon in most foodand bioprocess industries. Continuous or batch processes lead to fouling of the equipment atvarying rates (from minutes up to years) and propensity (from micrometers up tocentimetres). The control and understanding of fouling phenomena is clearly relevant toindustry: reduction of process performance, energy consumption, sanitary risk and watermanagement. To monitor fouling, various devices have been reported in the literature including rheological,electrical, chemical, mechanical, optical, sonic, ultrasonic, and thermal methods eachexhibiting its own specificities, advantages, and disadvantages. In this presentation, the main lab and industrial techniques dedicated to monitor fouling willbe reported as a benchmarking of techniques, scientific works, patents and industrial sensors
