Vega Level Instruments

Measuring techniques for continuous level measurement

In continuous level measurement, the level of a medium in a tank or silo is detected with the help of different measuring methods and converted into an electronic signal. The level signal is either displayed directly on site or incorporated into a process control or management system.
Typical applications for continuous level measurement are process tanks, storage tanks or silos in the process industry.
The measured media are:
  • liquids
  • pastes
  • powders
  • bulk solids

VEGAPULS: Level measurement with radar

In continuous non-contact level measurement with radar, the sensor sends microwave signals towards the medium from above. The surface of the medium reflects the signals back in the direction of the sensor. Using the received microwave signals, the sensor determines the distance to the product surface and calculates the level from it.
Liquids and solids are commonly measured with this measuring technique.
The advantages
  • Non-contact level measurement with radar is characterized by especially high measurement accuracy
  • Measurement is not affected by temperature, pressure or dust
  • User-friendly adjustment saves time

VEGAFLEX: Measurement of level and interface with guided wave radar (GWR)

In level measurement with guided wave radar, microwave pulses are conducted along a cable or rod probe and reflected by the product surface. The measuring probe of the TDR sensor ensures that the signal reaches the medium undisturbed. Liquids, bulk solids and separation layers (interfaces) in liquids are commonly measured with this measuring technique.
The advantages
The TDR sensors measure reliably despite:
  • steam
  • pressure and temperature fluctuations
  • dust and noise
  • buildup and condensation

VEGASON: Ultrasonic level measurement

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. Ultrasonic sensors are ideal for simple standard applications, both for liquids and for solids.
The advantages
  • The compact design of ultrasonic sensors allows easy installation
  • Non-contact measurement with ultrasonic technology operates independently of product characteristics
  • Cost-effective measuring method for wear and maintenance free operation

VEGACAL: Capacitive level measurement

In capacitive level measurement, the sensor and the vessel form the two electrodes of a capacitor. Any change in level causes a capacitance change, which is in turn converted into a level signal.
Thanks to versions with shortenable cables and rods, the capacitive level sensors cover a wide variety of applications.
The advantages
  • Capacitive level measurement enables measurement without blind spots over the entire sensor length
  • Fully insulated capacitive sensors also measure aggressive liquids
  • Cost-effective measurement for trouble-free and maintenance-free operation

VEGABAR and VEGAWELL: Hydrostatic level measurement

In hydrostatic level measurement, the measuring cell of the pressure transmitter detects even the slightest 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 then outputted as an output signal. Different types of measuring cells are used in level measurement based on the hydrostatic principle.
The advantages
  • Level measurement with hydrostatics is totally unaffected by foaming or vessel installations
  • Ceramic measuring cells offer excellent long-term stability and high overload resistance
  • Metallic measuring cells also cover larger measuring ranges

PROTRAC: Radiation-based level measurement

In radiometric, i.e. radiation-based, level measurement, a slightly radioactive isotope emits focused gamma rays.
The sensor, which is mounted on the opposite side of the vessel, receives this radiation. Since gamma rays are attenuated when penetrating matter, the sensor can calculate level, point level, density or mass flow from the intensity of the incoming radiation.
The advantages
  • Maximum operational reliability even in the harshest environments
  • Measurement is independent of pressure, temperature and product aggressiveness
  • Measuring system can be installed on the outside of a vessel during ongoing production
