(Virtual Showroom) Continuous level measurement provides valuable process insight in the energy sector, but point level measurement delivers the decisive moment of action. Whether preventing overfill, protecting pumps from dry running, or safeguarding critical equipment, reliable point level detection is essential to safe and efficient operation.

Across sub-Saharan Africa’s energy landscape, from coal-fired power stations and hydropower facilities to renewable energy infrastructure and emerging hydrogen applications, point level switches must perform consistently under demanding process conditions. Vibrating level technology has proven itself as a robust, product-independent solution for both liquid and bulk solid applications, delivering millimetre-precise switching with minimal maintenance requirements.

VEGA’s range of vibrating point level instruments is engineered specifically for these challenges, offering dependable performance across the full energy value chain.

Protection and Process Reliability

The VEGASWING 63 vibrating level switch is specifically engineered to provide accurate and reliable point level detection in a wide range of liquid applications within the energy sector. It is suitable for use with liquids possessing densities between 0.5 and 2.5 g/cm³, ensuring consistent switching performance regardless of the mounting position or the characteristics of the medium.

A key feature of the VEGASWING 63 is its tube extension, which enables the switching point to be positioned up to 6 metres away from the installation site. This design offers exceptional flexibility for placement in tanks, vessels, and sumps, making it possible to achieve optimal switching points even in situations where a compact sensor would be insufficient.

The instrument is commonly utilised in applications such as overfill protection for fuel, oil, and chemical storage tanks, dry-run protection for pumps, and empty or full vessel detection in auxiliary systems. Its product-independent switching point feature eliminates the need for calibration with the process medium, streamlining commissioning and simplifying maintenance tasks. These advantages are particularly significant in remote or resource-constrained energy installations, where efficiency and reliability are paramount.

Reliable Switching

For liquid applications that involve elevated temperatures and pressures, the VEGASWING 66 provides reliable and accurate point level detection where standard instruments may not suffice. This high-performance vibrating level switch is engineered for use with liquids possessing densities from 0.42 to 2.5 g/cm³, making it well suited to demanding and variable process environments.

The VEGASWING 66 is available in both a compact form and with a tube extension of up to 3 metres, offering flexibility for installation in a variety of locations. It is commonly utilised in critical applications such as steam generators and boiler systems, condensate and feedwater tanks, and high-temperature auxiliary vessels within thermal power plants.

Its robust construction ensures continuous and dependable operation across a wide spectrum of process conditions. Additionally, integrated sensor self-monitoring enhances operational safety by providing ongoing assurance of instrument functionality.

As with all VEGASWING instruments, the switching point is independent of product characteristics, ensuring reliable performance and requiring minimal maintenance.

Reliable Detection

Bulk solids handling is an essential operation in both coal-fired power generation and biomass-based energy production. The VEGAVIB 63 vibrating rod level switch has been specifically designed to meet the demands of granular and coarse-grained bulk solids, accommodating materials with densities as low as 20 g/l.

This instrument features a tube extension, which allows for flexible positioning of the switching point up to 6 metres away from the mounting location. This capability ensures precise level detection in various settings, including silos, bunkers, and conveyor transfer points, optimising operational efficiency and safety.

The VEGAVIB 63’s smooth and seamless vibrating rod construction is engineered to prevent material build-up and bridging, which can often compromise the reliability of level detection. This design also facilitates easier cleaning and maintenance, supporting uninterrupted operation even in challenging environments.

The VEGAVIB 63 is ideally suited for a range of critical applications in energy facilities, including high and low level detection in coal bunkers, overfill protection for storage silos, and monitoring at conveyor transfer points. Thanks to its medium-independent setup and minimal maintenance requirements, this instrument excels in the harsh, dust-laden conditions typical of modern energy operations. Its design ensures reliable performance and operational efficiency even in the most demanding environments.

Fine-Grained and Powdered Bulk Solids

When it comes to powdered and fine-grained bulk solids, such as fly ash and fine coal dust, the VEGAWAVE 63 vibrating fork level switch offers reliable and consistent point level detection. This instrument is engineered to handle materials with densities as low as 8 g/l and particle sizes up to 10 mm, making it ideal for challenging applications in the energy sector.

The VEGAWAVE 63 features a robust tuning fork design that ensures stable switching performance, even in the presence of adhesive or abrasive materials. Its tube extension, which can reach up to 6 metres, provides flexibility for precise placement of the switching point according to specific process requirements.

This level switch offers several key advantages: it reliably detects both minimum and maximum fill levels, delivers a product-independent switching point, and requires no calibration with the process medium. Additionally, its low maintenance demands and long service life make it a dependable choice for demanding process environments.

Point Level Technology for Energy Applications

Point level switches have become a mainstay in the energy sector, thanks to their exceptional reliability and straightforward operation. These devices offer several significant advantages, including millimetre-precise switching accuracy and consistent performance that is not affected by the properties of the measured medium. Their design ensures minimal maintenance requirements and allows for rapid commissioning, while their robust construction guarantees durability even in the harshest industrial environments.

As sub-Saharan Africa strives to maintain a balance between conventional energy generation and the implementation of renewable energy sources and future fuels, the importance of reliable point level detection cannot be overstated. Such detection is crucial for maintaining plant safety and ensuring continuous, efficient operations.

VEGA’s range of point level switches, including the VEGASWING, VEGAVIB, and VEGAWAVE series, are engineered to provide dependable and application-specific level detection solutions. These instruments are widely used across both liquid and bulk solid processes in the energy sector, supporting operational excellence throughout a variety of facilities.
