Milk from large dairy farms is processed and converted into powdered milk for ease of shipment. The powdered milk is stored in large silos, typically 35 ft. to 60 ft. high. The measurement is important for inventory control and indication of when the silos should be emptied.
Traditional “Ultrasonic” measurements only gave level indication in the smallest silos and did not provide reliability in the dusty atmosphere during filling and emptying. In many cases, the silos needed to be manually sounded with rope and weight. This proved to be a problem as the FDA inspectors, who visit frequently, are very critical of any contact form of level measurement. Compliance with the FDA motivated the end user to eliminate any device that may be considered nonsanitary by the FDA inspectors.
Drexelbrook installed a DR7000 continuous level transmitter
with a DN80 Horn with extension on a Sanitary Triclover fitting. The DR7000 level transmitter
uses 24-26 GHz FMCW Radar technology to make a continuous level measurement regardless of dust, vapors, moisture content or moisture variations of the low dielectric powdered product. The DR7000 level transmitter
is now providing reliable non-contact, sanitary continuous measurement of the powdered milk level in the tallest silos.
