There are different types for level indication, from simple LED digital displays for the evaluation of a 4-20 mA signal for installation in control cabinets or up to wall mounted to touch panels and web server modules with visualization software. The technologies can be configured on a project by project basis and adapted to customer requirements.
What is the Miners Canary?
In order to define the correct level measurement technology it is essential to analyze the different process parameters of the single application such as material properties, process temperatures, pressure and connections as well as the process atmosphere. The selection of the right level measurement technologies, their correct configuration and smart positioning will save substantial costs and add up to a significant improvement in the plants’ economic efficiency over its lifecycle.
Smart TDR with helpful diagnostic capabilities
For the cellulose production of a wood manufacturing plant in South America, the guided wave radar was implemented in several water tank constructions within the maceration processes. The modern, high-quality TDR technology ensures a continuous production process of the plant. Uninfluenced by changing process conditions, TDR sensors detect the level reliably and precisely and thus offer optimum support for a smooth process flow.
High solids content & moving surface
Concerning precise interface measurement of different solids in liquids there are popular project planning options for continuous level monitoring with lot systems and point level detection with vibrating forks. A company in England who manufactures stone recovery plants for the quarrying industry implements the electromechanical plumb bob NivoBob® for the detection of interface levels with the right feeling for the separating layer. The operator was looking after a principle that is sensitive and simple.
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.
Innovative solutions for cooling tanks of the power industry: Contact-free radar sensor for content level measurement detection in seawater tanks
In Malaysia, a plant operator in the power generation field was looking for a smart solution for continuous level monitoring of its seawater tanks. To meet the challenges of space constraints and the salty atmosphere within the containers with robust accurate content detection, the NivoRadar® NR 3000 contact-free radar sensor with robust stainless steel housing was used.
Guided wave radar technology for continuous level measurement in ethanol tanks
For the storage processes of ethanol of a Swedish producer the guided wave radar for continuous level determination was implemented within several tanks. When selecting a suitable measurement technology, the main focus was on reliability, durability and safety. Further high demands were placed on the robustness and flexibility in the range of applications for the measurement technology. The device to be used for the highly flammable liquid has to be certified accordingly.
Mechanical, non-contact or guided microwave
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 degree of compatibility for different process containers provide the optimum support. 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. The UWT range offers capacitive measurement technology, transducers as well as mechanical solutions for use in solids and liquids.
Guided wave radar in narrow storage silo for overfill protection and empty message
Every year, over 40 million cubic meters of ready-mixed concrete is processed in Germany. Already 85% of all concrete and fresh mortar required on construction sites are mixed in ready-mixed concrete plants. In aggregate, quarry and mining applications, the conditions are often harsh, noisy and dusty. The TDR level measurement devices 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.
Lot solutions as quick and easy measurement device, rotating paddles for extreme temperatures & capacitance RF probes for specialities
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.
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 a challenge for the right choice of instruments.
Thus the selection of measurement technology included first of all for the storage silos an electromechanical plumb bob that fits also perfect with the connection to a visualization system. Further for limit detection during several process steps rotating paddle switch and capacitive rod probe were installed. Here respectively the high temperature version was demanded.
A win – win situation: Silo management for grain mills and their customers
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. 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. 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?
