Vega Measuring techniques for level measurement 
In continuous level measurement, the instantaneous level at a measuring point is detected and converted into an electronic signal. The level signal is either displayed directly on site or fed into a process control or management system. Liquids, pastes, powders and bulk solids are measured with this method.
Typical applications for continuous level measurement are process tanks, storage tanks, silos or mobile containers in the process industry, e.g. the chemical and pharmaceutical industry, as well as in environmental engineering, water and sewage systems, power generation, metal production and offshore systems.
Every industry places its own very specific demands on measurement technology. VEGA offers many different physical measuring principles for level measurement. It can provide a continuous level sensor perfectly adapted to the properties of the medium as well as the individual process conditions at the measuring point.

  JONWEB just only offer VEGA Level parts such as Vega Radar level / Vega Microwave level / Vega Ultrasonic level / Vega Capacitive Level / Vega Radiation Level... Another Vega instruments, please send enquiry to our PA Sales Team.

 Vega Level measurement with Radar : VEGAPULS Series
 vega radar level measurementVEGA has been a technology leader in the area of radar level measurement for many years. In almost every industrial process, the levels of liquids, muds, pastes, powders and bulk solids have to be measured continuously in tanks, silos, containers and pipelines. The requirements placed on the measuring instrument are as different as the types of products whose levels must be recorded, no matter whether it’s process water or sewage, food, lye or acid, oil, cement or mining debris. External influences, such as very low or high temperatures, under- or overpressure, vibration or abrasion, are also factors the respective measuring instruments have to cope with when measuring the filling level. Radar sensors from VEGA offer a suitable solution for each of these different applications.

The VEGAPULS sensor emits short radar wave pulses in the direction of the medium. The surface of the medium reflects the radar waves which are then received back by the antenna system of the radar sensor. Finally, the instrument calculates the level from the running time of the radar signals.

Radar sensors for liquids
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.

Radar sensor for bulk solids
The high-frequency K-band sensors VEGAPULS 67 and 68 are applied for level measurement in bulk solids. Due to the excellent signal focusing, internal silo installations or buildup 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 m.

 Vega Level measurement with guided microwaves: VEGAFLEX Series
In this type of radar level measurement, microwave pulses are conducted along a cable or rod probe and reflected by the product surface. The measuring probe ensures that the signal reaches the medium undisturbed. Liquids, solids and separation layers (interfaces) in liquids are commonly measured with this measuring technique.

Applications in liquids
Density fluctuations, steam generation or strong pressure and temperature fluctuations do not influence the measuring result. Also buildup on the probe or the vessel wall do not influence the measurement. An ideal application is level measurement in a bypass tube where even products with dielectric values below 1.6 can be measured reliably. Also connection tubes – bypass tubes have no influence.

Applications in bulk solids
Typical problems in bulk solids such as e.g. dust and noise generation or condensation do not influence the reliability. Also the shape of the material cone or the product properties, e.g. the change from dry to wet sand do not influence the measuring result. Since the instruments are already preadjusted, setup is limited to connection of the sensor.

Interface measurement in liquids
The measuring principle was developed for detection of the interface. Typical applications are measurements of oil and solvents on water. The microwave impulse is reflected a second time on an interface with different dielectric value. This allows the detection of a second level. The advantage against displacers or floats is that the measuring principle is independent of density and does not use any moving parts. Through the digital communication interfaces or connection of a VEGAMET 625, the output of both levels is possible.

 Vega Level measurement with guided Ultrasonic : VEGASON Series
In non-contact ultrasonic level measurement, the sensor emits ultrasonic pulses in the direction of the medium, which then reflects them back.

The elapsed time from emission to reception of the signals is proportional to the level in the tank. Level sensors based on this measuring principle are ideal for simple standard applications, both for liquids and for solids.

The advantages : Non-contact ultrasonic sensors operate independently of product properties and even penetrate dusty atmospheres.

Measuring principle : Short ultrasonic impulses in to range of 10 to 70 kHz are emitted by the transducer to the measured product, reflected by the product surface and received again by the transducer. They spread with sound velocity. The time from emission to reception of the signals is proportional to the level in the vessel. The proven ECHOFOX signal processing filters out the correct level echo reliably from a number of false reflections. An adjustment with empty and full vessel is not necessary!


Application in liquids
Sensors with frequencies between 30 and 70 kHz are used for these applications. They operate independent of product properties and are ideal for water/waste water applications and the measurement of slightly corrosive acids and lyes. Also applications in gas-Ex areas can be equipped with these sensors.

Applications in bulk solids
Sensors with frequencies between 10 to 30 kHz are used for these applications. The lower switching frequency enables a considerably better penetration of dusty atmosphere. An adjustment with medium is not necessary. For applications in dust-Ex areas, approved sensors are available.

 Vega Level measurement with guided Capacitive : VEGACAL Series
The sensor and the wall of the container form the two electrodes of a capacitor. When the level changes, the electrical capacitance between the electrodes also changes. This change is evaluated by the electronics and converted into an output signal. Robust cable and rod versions cover a variety of applications.

The advantages
Fully insulated instrument versions also measure aggressive liquids or highly adhesive media.
Partly insulated versions perform reliable switching in powdered and granular bulk materials. The construction and quarrying industry, in particular, benefits from the sturdy build of these instruments.

Measuring principle
The proven capacitive measuring principle is one of the most common measuring principles for level measurement in the industrial measurement technology. Sensor and vessel form the two electrodes of a capacitor. A capacitance change caused by a level change is processed by the integrated electronics and converted into a switching signal. The level measurement is carried out via the complete sensor length without a dead zone. Thanks to cable and rod versions, suitable instruments are available for all applications. 

Applications in liquids
Mainly fully insulated instrument versions are used in these applications. Hence measurements of corrosive liquids or adhesive products are no problem. The mounting of the instruments is easy and the rugged construction is the basis for an interference and maintenance free operation.

Applications in bulk solids
Partly insulated versions are preferably used in bulk solids. Also here, we have the proven, rugged configuration as basis for the manifold and reliable use, e.g. in the aggregates and mining industry.

 Vega Hydrostatic level measurement
The measuring cell of the pressure transducer detects small changes in hydrostatic pressure, which increases or decreases depending on the filling level. The acting pressure is converted into an electrical signal by the integrated electronics and converted into an output signal. Different types of measuring cells are used in level measurement based on the hydrostatic principle....
 Vega Radiation-based level measurement 
In radiometric, i.e. radiation-based, level measurement, the measuring device is mounted outside the tank. A cesium-137 or cobalt-60 isotope sends out focussed gamma rays. On the opposite side of the tank, a sensor picks up the gamma rays that have been attenuated by the medium. The level, point level, density or mass can be calculated via the intensity of incoming radiation....
