Modern solutions for efficient storage processes Measurement technology Rotonivo® and NivoBob® combined with data visualisation NivoTec® Modern, high-quality technologies ensure a continuous stress-free manufacturing process in plants. When it comes to detecting fill levels in silos and material processing operations, sensors with a high level of compatibility for different process containers provide the optimum support for a smooth process. Depending on the processing stage, the material to be controlled can be of very different nature and place different demands on the measurement technology to be used. Users from different industries with a number of scattered storage silos consider it increasingly necessary for their plants to be equipped with automated visualisation and monitoring of the data in addition to continuous measurement of the fill levels. In order to guarantee a professional solution in terms of precision and process reliability for content measurement during the various stations in the manufacturing process to support a production facility, it is necessary to react to the respective

Plant operators are busy keeping pace of the wide range of challenges presented by raw materials of the building sector, the changing operating conditions in silos or pipelines or the need for ex-certificates. Such requirements call for measurement solutions that are versatile, whilst representing a cost-effective investment and offering versions fully equipped to meet a wide variety of these requirements. Due to the fast development of the building and quarry industry in the MENA countries during the past years, the demand for more solution approaches for applications of cement plants there has increased. Solutions of appropriate sensor technology for content and point level measurement have to be found in order to support the process flow of the cement production in the most reliable way. - Case study: In one of Saudi Arabia’s largest cement plants UWT was confronted with especially harsh working conditions. For his cement silos the plant operator was looking after reliable contents measurement technology as well as after a flexible sensor system for level limit detection. The combination of a very high dust generation and an extremely high process temperature was

Solutions in the dam - Compact limit switch for process optimization for hydropower plants as a backwater detector for wood chip conveyance. One of the largest energy supply companies in the UK was looking for modern equipment for its northern dam with flexible metering technology. The electricity and natural gas supplier for local households and businesses has been focusing on hydropower generation for several years, in addition to wind power. The centrepiece of the dam’s hydropower plant is the installed wood chip system, which was recently implemented to curb pollution in the dam. Accumulated wood chips are transported to a designated storage area via a series of chain conveyors. These chain conveyors need to be monitored with modern and robust measurement technology. Namely, an indicator that functions as a full detector is required in the transfer chutes in order to detect a blockage with the wood chips in good time. Full detection for wood chip conveyance Together with the subsidiary UWT (UK) Ltd in Shrewsbury, a safe solution was found after several tests with oscillating probes that work according

Bakeries, the customers of the mills, often place their orders to late and the mills are faced with having to supply material immediately in order to avoid production stop at the bakeries. In Germany alone there are more than 260 large flour mills, in Asia the grain market is significantly greater and a very important industry. All around the world the situation is similar: Well-planned routes and carefully calculated stock levels are vital to achieve max. cost optimization during the material delivery process, however these are more than often jeopardized by daily reality. This leads to unnecessary logistics costs caused by multiple deliveries and ultimately to an increase in costs for sides, the supplier and the customer. This is obviously in no one’s interest. But why are we confronted with these “fire-fighting” situations and how can they be avoided? Lack of storage management in bakeries Even bakeries with multiple storage silos often do not have an automated level monitoring system to control their inventory levels. Therefore these stocks have to be checked manually on a regular basis and an order has to be triggered to the flour supplier

Guided wave radar in narrow storage silo for overfill protection and empty indication. Robust and reliable for a continuous, stress-free production process. Robust and totally reliable In aggregate, quarry and mining applications level measurement devices need to be robust with total reliability as standard to ensure a continuous stress-free production process. Modern level measurement For a concrete and cement manufacturer in Germany who has implemented guided wave radar sensors this level measurement technology offered multiple support for his storage process optimization. The TDRs with their high compatibility are used for consistently accurate continuous level detection under difficult varying process conditions, such as high pull-off forces, caking or condensate formation. Unaffected by dust and build-up The stored raw products and additives undergo different processing stages on the way to the final mortar and different kinds of concrete, ready-mixed concrete and special concretes. The solids in particular have different densities, particle sizes with different dust development and a differing moisture content.

Learn more about our radar level transmitters to reliably measure solid and liquid materials in silos and tanks. We have solutions for the most diverse industries. Our radar sensors include a non-contact series NivoRadar® 3000 and a guided wave radar serie NivoGuide®3000 for solis and NivoGuide® 8000 for liquids. Electromagnetic waves form the basis of level measurement with radar. A radar sensor emits a focussed electromagnetic wave that is reflected by objects as an echo and is then evaluated by the sensor. In addition to free-radiating radar sensors, the radar category also includes those based on guided microwave technology, which are referred to as guided radar, TDR (time domain reflectometry) or also GWR (guided wave radar) sensors. The fundamental difference between free-radiating and guided radar sensors is the way the electromagnetic waves reach the medium to be measured. While free-radiating radar sensors use special types of antennas to transmit the waves in the direction of the material without contact, guided radar sensors require a probe (rod or cable) as

Point level detection with RFnivo® and the coating PPT with innovative corrosion protection In power plants, the demands made on the fill level sensors can be very high due to the fact that the sensors come into contact with aggressive media such as sulphur oxides, heavy metals or even acids. Where limit switches are used for dust detection in flue gas cleaning, they need to be robust enough in order to deliver reliable and consistent performance. Often maintenance costs or replacement of these sensors can be very high due to their quality not being adequate to meet the demands and so they achieve only a short operating life. This is particularly evident in measurement tasks in flue gas cleaning within waste incineration plants. Longer service life due to increased corrosion resistance UWT has further developed the RFnivo® 3100 capacitive level limit switch for this type of measurement task in the dust extraction of flue gases so that it meets and withstands the demanding conditions. All process-contacting parts of the sensor have been designed to be completely

Simple and reliable measurement technology by UWT A level limit sensor has to cope with low bulk density, bridging, caking, abrasiveness, corrosion, leverage forces, high and low process temperatures, electrostatic charging and so on. Rotating level limit switches of UWT have been designed to meet these challenges of different industry sectors and cover various changing approaches, also within extraordinary applications. The rotating paddle switch can be used as full, demand or empty detectors in silos or containers. The trusted, multifunctional and maintenance free unit for level monitoring of bulk goods is versatile and has a modular design. With its simple electromechanical measuring principle it can also be adapted for extreme process conditions. A motor driven shaft causes the vane to rotate. Once the material level reaches the vane, thereby preventing further rotation, this creates a torque, which is converted via a switch to an electric signal. When the vane is free again of the material, the output signal

With the Capanivo® 7000 and Capanivo® 8000 series and the

Project planning options for interface detection with NivoBob® or Vibranivo® from UWT There are several industries where sludge levels or solids in liquids need to be measured. For example, in sediment containers or basins, filters or lamella separators in the metal industry, chemical plants, lime or gravel works and the waste water industry. The measuring accuracy and durability of the sensor technology is important. Dirt, chemicals and gases often affect the sensors and require special resistance. The NivoBob® series NB 3300/3400 meet the requirements of many interface measurements and are very reliable due to the simple measuring principle. For level evaluation an analogue signal 4-20mA and a Modbus RTU/Profibus DP interface are available. Vibrating forks of the Vibranivo® series VN 1000 or VN 5000 can be used to measure the level of sludge and solids in liquids. The parts in contact with the medium are made of resistant stainless steel. With the versions VN 1030 and VN 5030 even depths of approx. 4 m when installed from above in a tank or basin.

Solutions for tricky level measurement challenges What is radar? Radar is the abbreviation for "radio detection and ranging" which means "radio-based location and distance measurement". This technology is based on electromagnetic waves. A radar device emits a concentrated electromagnetic wave, which is reflected by objects as an echo and then evaluated by the device according to various criteria. Depending on the application, the following information can be obtained from the reflected waves: -the angle or the direction to the object -the speed of an object (Doppler effect) -the contours of an object -the distance to the object The latter point means that radar technology is also used for determining fill levels. This has become increasingly important in recent decades and has been continuously developed. The areas of application now extend from simple storage tank applications to complex process containers with a wide variety of challenges.

PPSChemical resistance & compact design with the probe with 1-inch process connection Level indicators working with the capacitive measurement principle can be used in all types and shapes of tanks, regardless of whether these are metallic or non-metallic. Due to their high sensitivity, their compactness and the range of probes, they are suitable for a wide variety of industrial process requirements. A well-known manufacturer of aluminum sulfate in Peru was looking for a compact level measurement for its raw material tanks with 98% sulfuric acid. Due to the strong corrosion caused by the acidic material, the decision was made to implement the robust capacity indicator Capanivo® CN 7000 from UWT GmbH. PPS probe with 1-inch process connection Chemical resistance & compact design Sulfuric acid is extracted from sulfur in a number of ways and is one of the most dangerous acids known in the world.
