APPLICATION NOTE Food & Beverage Level measurement on flour mill silos • Remote stock control with reduced installation and maintenance costs • Clear vision even through dust-laden air • Accurate level measurement on non-flat surfaces 1. Background Most flour mills estimate their stock indirectly by calculating the amount of product loaded and used. Due to the increasing price of wheat, reliable stock management has become an important issue for this industry. 2. Measurement requirements The mills keep a permanent stock and each product is immediately available to the end user. The product,...

APPLICATION NOTE Flour silos Dust ﬁlter 4. Customer beneﬁts There is no longer any need to climb up to top of the silo roof to check the level of product: the stock is now continuously calculated and displayed on a computer monitor in a control room. By combining the high signal dynamics and FMCW radar technology, the OPTIWAVE 6300 C guarantees reliable measurement even on low reflective product and in very dusty atmosphere. Product build-up on the antenna is no longer an issue with the Drop-antennas made of PP or PTFE. Their shape, unlike traditional horn antennas, prevents a crust forming...

APPLICATION REPORT Food & Beverage Level measurement in ﬂour silos with intense dust formation • Monitoring of ﬂour supplied for the production of frozen pizzas • Non-contact (FMCW) radar level measurement of low reﬂective medium • Signiﬁcantly higher measuring performance in a test comparison with pulse radar devices 1. Background Nestlé Wagner GmbH is among the largest manufacturers of frozen pizza in Europe. Today, the longestablished company produces these baked goods with about 1400 employees at two locations in Nonnweiler, Germany. Because the production facilities run in continuous...

APPLICATION REPORT 3. KROHNE solution During the test phase, the good measuring performance of the non-contact (FMCW) radar level meter OPTIWAVE 6300 C proved convincing. Moreover, the measuring instrument was the only one that did not require a purge connection. This was critical to the subsequent selection of the KROHNE device for level measurement on a total of seven ﬂour silos. With its 24...26 GHz FMCW radar, the OPTIWAVE 6300 is designed for level measurement in the very dusty atmosphere of the ﬂour silos. Each measuring device is equipped for this task with a DN 80 / 3" drop antenna...

APPLICATION NOTE Food & Beverage Level measurement in starch production • Storing bran in 20 meter high silos • Permanent monitoring of bran stock for supply inventory • Low operating costs due to simplified and maintenance-free installation 1. Background The world’s production of starch and its by-products currently amounts to 6.5 million tons per year. Obtained mostly from corn, wheat and potatoes, starch is used as an additive in various industries: e.g. food processing, papermaking, clothing, chemical and pharmaceutical industry. Several processes allow for the production of starch: One...

APPLICATION NOTE 3. KROHNE solution KROHNE delivered 2 OPTIWAVE 6300 C with a DN 80 (3”) Drop antenna KROHNE delivered 2 OPTIWAVE 6300 C with a DN 80 (3”) Drop antenna made of plain PP and a G1½" process connection. Fitted on each silo made of plain PP and a G1½ process connection. Fitted on each silo roof, the non-contact radar (FMCW) level meters measure the level of roof, the non-contact radar (FMCW) level meters measure the level of bran and communicate the results to the DCS in the control room. bran and communicate the results to the DCS in the control room. The OPTIWAVE 6300 C uses...

APPLICATION NOTE Food & Beverage Measuring layer thickness in a centrifuge • Continuous measurement of layer thickness when filling centrifuge • Controlling the layer thickness during the spin process • Automated filling process 1. Background A sugar producer fills a centrifuge with hot molasses sugar to press the moisture out of the molasses at high speed. The thickness of the layer of molasses on the wall of the centrifuge is reduced in the process. The layer thickness is thus a measurement of the moisture content of the layer of molasses. The centrifuge is the shape of an upright barrel...

APPLICATION NOTE 3. KROHNE solution For this type of application, KROHNE supplied 4 OPTIWAVE 7300 C radar level measuring devices with DN 50 / 2" horn antennas and G 1½" connection. The existing constructions were used for mounting. Thanks to FMCW radar technology, the OPTIWAVE level meters measure over a very wide dynamic range. That is why neither the minimally reflective surface of the molasses layer nor the high speed of the centrifuge when filling and during the spinning process affect the measurement of the layer thickness. Following each spin cycle, all parts that come into contact...
