VEGA Level Sensor

Render Technology Solutions deal with all kinds of VEGA Level Sensor

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.

VEGA Radar Level Sensors

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

VEGA Guided Wave Radar Sensors

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 TDR sensors measure reliably despite:

  • steam
  • pressure and temperature fluctuations
  • dust and noise
  • buildup and condensation

VEGA Ultrasonic Level Sensors

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.


  • Price-favourable solution for simple applications
  • Maintenance-free operation through non-contact measuring principle
  • Reliable measurement independent of product features

VEGA Capacitive level Sensors

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.


  • 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
