In the petrochemical industry in order for the crude oil process to run continuously and smoothly care has to be taken when storing raw and finished products. Delivery of the crude oil is via pipeline or ship and stored in a large tank until it is ready for final processing.
Accurate level measurement of products of distillation is essential whilst they are being stored in different sized tanks.
In the past it was expensive as calibratable measuring devices were implemented for level measurement. Nowadays cheaper and low maintenance measuring systems are used for small and medium sized tanks. Products are now usually measured by calibratable flow meters while being moved.
The radar sensor VEGAPULS 62 is suitable for level measurement especially in small and mid-size refinery vessels. Being small and light, the level sensor can be mounted without difficulty in an existing mounting boss, or integrated into a manhole.
With an accuracy of 3 mm, the VEGAPULS 62 sensor is ideal for inventory tank management and can easily be coupled with superordinate systems. Through the use of a temperature adapter, process temperatures up to 200 °C can be realised enabling level measurement of highly viscous distillation products such as lubricating oil or bitumen. VEGAPULS 62 has also proven itself very well as overfill protection in floating roof vessels.

Until now, mechanical measuring systems such as float gauges or displacers were often implemented. To guarantee precise measuring results, such devices (VEGAFLEX 61) are used mainly in standpipes. Due to the large equalisation holes in the pipes, it is often impossible to replace existing systems with free radiating radar sensors – the holes cause interfering reflections.
This is a situation in which the guided microwave device provides a simple, as well as reliable, solution for level measurement. When the sensor is mounted in the center of the existing standpipe, a coaxial measuring system with optimal signal transmission is created. The result is high accuracy and dependability, without large expenditures for installation and setup.
In principle, a continuous measuring system can be implemented for overfill protection. However, as a completely different measuring principle, the vibrating level switch VEGASWING 63 provides additional safety. Independent of product characteristics, the level sensor reliably detects the threshold level and thus ensures a high degree of plant safety.
The annual instrument check is carried out quickly and reliably with a simple push of a button on the instrument. VEGASWING 63 is ideally suited for leakage monitoring in tank enclosures.

VEGA – World Leading Manufacturers Of Level & Pressure Sensors
VEGAFLEX81 level sensor provides a temperature operating range of -60 to 200°C and up to 75 metres measuring distance.
A large butchery requires the measurement of the level of ammonia in the storage room of its meat-packing facility. Level monitoring is required in the low-pressure receiving tank in the system.
The upper part of the tank contains ammonia vapour which is transformed into liquid form in the compressor before being pumped back into the tank.
When pumped back into the lower part of the tank the liquid ammonia passes through the cold storage room where it heats up and becomes ammonia vapour again. It rises to the top part of the tank and the cooling cycle begins again.
Monitoring the level of the liquid ammonia is particularly important for the operation of the system because if the liquid phase in the vessel gets too high, liquid ammonia would be sucked into the compressor, thereby causing serious damage.
The biggest challenges in this application arise from the special properties of ammonia, its relatively low dielectric constant and the process temperature of -30° C. In a gaseous state, ammonia can diffuse through standard industrial seals and destroy the electronics in the instrument housing within a very short time.
The VEGAFLEX 81 level sensor is used to measure the ammonia effectively.
VEGA VEGAFLEX 81 is an intrinsically safe sensor which can be equipped with a borosilicate glass feedthrough (second line of defense) for ammonia applications. This feedthrough is gas tight and resistant to ammonia vapour.
The temperature range of the sensor, -60 … +150° C, matches the requirements perfectly. The coaxial measuring probe protects the borosilicate glass feedthrough and is ideal for liquids with a low dielectric constant.
The VEGAFLEX 81 guided radar level sensor can be used for all liquids including bitumen and liquefied gas. It can be used for storage containers, standpipes, in a metering tank or in tank farms. The VEGAFLEX 81 measures the level or interface (separation layers) of liquids with great reliability and accuracy.

VEGA Sensors – Level & Pressure Instrumentation For The Renewables Industry
The renewable energy sector continues to grow and wind turbines continue to be subjected to severe environments. On offshore wind farms the turbines have to contend with rough seas and windy conditions as well as corrosive salt water environments. It is inevitable that when the wind turbine plant is constructed seawater will end up in the turbine tower. Leaks need to be sensed and detected as they can lead to accelerated rates of corrosion if the water level is not monitored constantly.
VEGAFLEX 81 provides liquid level measurement from a temperature range of -60 to 200°C over 75 metres distance.
Guided Radar VEGA VEGAFLEX 81 for level measurement and interface in all liquid types provides reliable measurement data.
VEGAFLEX 81 guided wave radar level sensor is able to function regardless of the harsh atmosphere inside the wind turbine tower as it is made of high-resistance materials.
VEGAFLEX 81 wind turbine level sensor is very adaptable, simple to install and can still function when the electronics are up to 10 metres away from the sensor.
For further information on the VEGAFLEX series of guided wave radar level sensors that T&D offer suitable for use in the renewable energy sector please contact our sales office today.

Level Sensors
A guided wave radar level sensor utilising VEGA VEGAFLEX technology uses microwave pulses which are conducted along a cable or rod measuring probe. The measuring probe of the level sensor ensures that the signal reaches the medium undisturbed. The pulse signal is reflected by the mediums surface and is received by the processing electronics. This information is then used and converted into level information.
Level Sensors
The level of almost any liquid or solid can be measured using VEGA guided wave radar sensors. Guided radar is virtually unaffected by changes to product or process temperature, pressure, density, conductivity, vapours, build up or dust. No moving parts mean the radar level sensors are extremely reliable and eliminates the need for recalibration.
All guided wave radar sensors have built in linearisation software to calculate the level versus shape and provide direct output of volume on:-
VEGA are the worlds’ No.1 process radar manufacturer, with the experience of over 200,000 successful installations. In 1997 VEGA introduced the first two wire, loop powered radar to the market and are the established leaders in this field.
VEGAFLEX series of guided wave radar level sensors are usually mounted from the top. Calibration is easy and uses a small entry to the vessel (from ¾” BSP). VEGAFLEX is part of the plics® family:

VEGA – The Level Sensors & Measurement Specialists
Level Sensors
A radar level measurement instrument uses microwave signals to determine the level of a liquid or solid.
The instrument is placed above the medium and emits a microwave signal which is reflected back to the sensor from the surface of the medium.
The radar level sensor uses this data to determine the distance to the product surface and is thus able to calculate the product level.
The radar level measurement technique is commonly used for measuring liquids and solids in the process industry – applications include process tanks, storage tanks and silos.
This non-contact form of level measurement, utilising VEGA VEGAPULS technology, mean the readings are not influenced by temperature, pressure or product properties.
Two different emission frequencies are available for the level measurement of liquids.
The compact, high-frequency K-band sensors VEGAPULS 61, 62 and 63 are particularly suitable for applications in which very high precision is required.
Excellent signal focusing is achieved even with small antenna sizes.
The low-frequency C-band sensors VEGAPULS 65 and 66, on the other hand, are better able to penetrate foam and strong condensate deposits and are thus suitable for especially difficult process conditions.
The high-frequency K-band sensors VEGAPULS 67 and 68 are applied for level measurement in bulk solids. Due to the excellent signal focussing, internal silo installations or build-up on the walls have no influence on the measurement.
The highly sensitive electronics, especially adapted to the requirements of bulk solids measurement, enables reliable level measurement of widely different products up to 75 metres.
