The challenge

The largest producer of animal feed in Chile needed a continuous level measurement for 15m high storage tanks, for various powdered base materials for the production of animal feed. It should work without contact to the product and meet the dynamic filling process via two filling lines. The application is very dusty. In addition, there are metal braces in the tanks, which make the installation and the function of a level sensor more difficult.

NR 3001 in the animal feed sector

Our solution

The continuous measuring radar sensor NivoRadar NR3100 was the best solution in this application. This sensor operates at a frequency of 78 GHz and has a beam peak of only 4 °. At a distance of 15m, the diameter of the beam is only about 1m. The sensor could be optimally placed and aligned with the flexible adjustment flange on the tank discharge. Thus, the metal struts were not in the measuring range of the beam. The high frequency of the sensor also provides an optimal echo confidence in this very dusty application. The standard air purge device for the lens antenna did not have to be activated.

The challenge

The customer was investing in a new SCADA system for a pet food manufacturing facility in the north of England. They wished to measure the contents in all their silos/bins/hoppers. These storage vessels were throughout the facility and held the raw materials, additives, semi completed products and final pre-bagging products.


The challenge the customer faced was that they wished to use one type of measuring device for all stages of the manufacturing process. At different stages of the production process the products had different densities, where different sizes from powder to pellets and had different levels of dust and moisture. The storage vessels also varied in height from 3m to 15m.

NB 3100 in the animal feed sector

Our solution

UWT proposed installing the NB3100 to all their storage vessels as it would cover the full range of heights, densities and dust volumes.

By using a unit fitted with a brushless motor this also allowed the customer to run the Nivobob on a continuous cycle for those vessels with a high feed or discharge speed.

CN 4020 in the animal feed sector

The challenge

The animal feed producer needs to control a hopper which supply the mixing systems with milled materials (corn, soya, rice, wheat, meat meal and husks). False alarms were quite frequent due to the material accumulated on the sensors. Also, it was a very dynamic process with silo supply many times a day, required a sensor that was reliable and fast response to increase the performance.
