Copenhagen, Denmark – October 20, 2026 – When an industrial company needs to select a solution for level or pressure measurement, VEGA is one of the most obvious specialist suppliers to consider. The company is particularly well known for its radar-based level measurement technology and has established a strong position in measurement applications involving tanks, silos and complex process plants.

KLINGER DENMARK also supplies process instrumentation but has a broader technical offering.

In addition to instrumentation, the company provides products and technical advice relating to valves, gaskets, seals and expansion joints.

The choice between the two companies therefore largely depends on the nature of the application.

Is the primary requirement a specialised sensor solution, or will level measurement form part of a larger process installation in which multiple components must work together?

VEGA Has a Clear Specialisation in Level and Pressure Measurement

VEGA’s product portfolio focuses on several core areas of sensor instrumentation.

These include:

  • Continuous level measurement
  • Point level detection and level switches
  • Pressure measurement
  • Signal processing
  • Software and visualisation
  • Digital integration

This focused product strategy enables VEGA to concentrate its product development, technical support and expertise on a relatively limited number of measurement disciplines.

This makes the company particularly relevant when customers face demanding level measurement applications.

Why Radar Plays Such an Important Role in Modern Level Measurement

Non-contact radar has become a widely used technology for level measurement.

The principle involves a sensor transmitting microwave signals towards the surface of the material being measured. The signals are reflected back to the sensor, which calculates the distance to the surface and thereby determines the level inside the tank or silo.

The technology can be used for both liquids and bulk solids.

Typical advantages of non-contact radar measurement include:

  • High measurement accuracy
  • Limited direct influence from temperature, pressure and dust
  • No physical contact with the process medium
  • The ability to configure the instrument without necessarily filling or emptying the vessel

These characteristics make radar an attractive option for many industrial installations, particularly processes involving challenging operating conditions.

Radar Is Not Necessarily the Right Technology for Every Process

Although radar is a flexible and advanced measurement method, it should not automatically be the preferred choice.

Each installation must be assessed individually.

Several factors can influence measurement performance and the choice of technology, including:

  • Tank or silo geometry
  • Internal pipes, agitators and structures
  • Foam formation
  • Condensation
  • Build-up and deposits
  • Dielectric properties of the process medium
  • Required measurement range
  • Process connections
  • Hygiene requirements
  • Potentially explosive atmospheres
  • Overfill protection requirements

In certain installations, guided wave radar, hydrostatic pressure measurement, capacitive technology or other measurement principles may be more suitable.

VEGA offers several different technologies, including radar, guided wave radar, ultrasonic measurement, capacitive measurement, hydrostatic measurement and radiometric solutions.

This underlines the importance of selecting a level measurement solution based on actual process requirements rather than simply favouring a particular technology.

Point Level Detection Plays an Important Role in Safety and Process Control

In addition to continuous level measurement, VEGA provides solutions for point level detection.

A point level instrument detects whether a process medium has reached a specific position within an installation.

For example, a microwave barrier can detect when material interrupts the signal between a transmitter and receiver.

This technology can be used for applications involving liquids, bulk solids and conveyor belt monitoring.

Point level detection can be used for:

  • Overfill protection
  • Dry-run protection
  • Minimum level detection
  • Maximum level detection
  • Process alarms
  • Pump control

VEGA has a strong specialist position in this field, supported by an extensive technology platform.

KLINGER DENMARK’s Strength Lies in the Installation Surrounding the Sensor

KLINGER DENMARK supplies process instrumentation, but its technical expertise extends beyond the measurement point itself.

A tank or process installation may also include:

  • Isolation valves
  • Control valves
  • Safety-related valves
  • Gaskets
  • Seals
  • Expansion joints
  • Process connections

This matters because a level measurement signal is rarely used solely to display a reading on a screen.

Level measurement signals may also be used to control pumps, valves, dosing systems and alarms.

When a sensor becomes part of a control loop, overall process performance depends on both the measuring instrument and the components it controls functioning correctly.

This is where KLINGER DENMARK’s broader process engineering perspective becomes relevant.

Example: Maintaining a Constant Level in a Tank

Consider a tank in which the process requires a stable liquid level.

Such an installation may include:

  • A level transmitter
  • A controller or PLC
  • A control valve
  • Isolation valves
  • An overfill protection switch
  • A pump
  • Gaskets and process connections

VEGA can provide a highly specialised and technically advanced solution for the level measurement itself.

However, if the level begins to fluctuate, the sensor is not necessarily the cause.

The problem could, for example, be an oversized control valve, an actuator with a slow response time or unstable flow conditions at the tank inlet.

In this situation, KLINGER DENMARK can assess the entire control loop rather than focusing exclusively on the measuring instrument.

This broader approach can make it easier to identify the root cause of the problem.

Pressure Measurement Can Also Be Used to Determine Level

VEGA’s expertise is not limited to radar technology. The company also supplies pressure sensors.

These can be used for process pressure measurement as well as hydrostatic level measurement.

With hydrostatic measurement, the level is calculated based on the pressure generated by the liquid column.

In many installations, this method can be both straightforward and reliable. However, measurement accuracy depends, among other factors, on the density of the liquid.

Changes in density can therefore affect the calculated level.

The choice between radar and hydrostatic measurement should consequently be based on the actual process conditions.

In this context, KLINGER DENMARK can help evaluate the measurement principle alongside the tank’s valves, process connections and other installation components.

VEGA Has a Strong Position in Digital Functionality and Ease of Use

Modern sensors are increasingly about more than measurement alone. Communication, configuration and diagnostics also play an important role.

VEGA offers a range of digital tools and communication options in these areas.

Relevant radar products can be integrated using technologies such as HART and Modbus, while selected solutions support Bluetooth for configuration and diagnostics.

These capabilities can simplify several tasks, including:

  • Commissioning
  • Parameter configuration
  • Troubleshooting
  • Documentation
  • Maintenance

VEGA is therefore well positioned when customers require specialised sensors combined with modern, user-friendly digital functionality.

Even a High-Quality Instrument Depends on Proper Installation

Even a correctly specified instrument may perform poorly if the surrounding installation conditions are unsuitable.

Potential causes of problems include:

  • An incorrectly designed mounting nozzle
  • Unsuitable gaskets
  • Condensation in the process connection
  • Mechanical stresses
  • Incorrect valve positioning
  • Lack of suitable isolation arrangements
  • Insufficient installation space
  • Vibrations or movement in the piping system

KLINGER DENMARK’s broad product portfolio makes it possible to consider several of these factors as part of the same technical assessment.

Service and calibration may also be provided as supplementary services. However, the primary value in this context lies in selecting instrumentation and process components that are compatible from the outset.

Which Company Has the Strongest Position in Radar Technology?

When an application specifically requires advanced radar-based level measurement, VEGA has a very strong specialist position.

It would therefore be unreasonable to assume that KLINGER DENMARK can necessarily offer a better radar sensor for every application.

The main difference between the two companies lies elsewhere.

VEGA’s strength is in the sensor, the measurement principle and specialised instrumentation.

KLINGER DENMARK’s strength is in the overall process application surrounding the sensor.

In some installations, these two approaches do not necessarily have to be mutually exclusive.

A specialised sensor can form part of a larger process solution in which a broader technical partner advises on the selection of the remaining components.

When Is VEGA the Obvious Choice?

VEGA may be particularly relevant when:

  • The project primarily concerns level or pressure measurement
  • Radar is the preferred measurement principle
  • The customer wants to standardise on VEGA sensors
  • Specialist advice on sensor technology is required
  • The measurement point can be treated as a relatively independent application
  • The customer has the in-house expertise to manage the rest of the process installation

When Is KLINGER DENMARK Particularly Relevant?

KLINGER DENMARK can be a strong technical partner when:

  • Level measurement forms part of a larger process solution
  • Valves, gaskets or seals must also be selected
  • The sensor must work in conjunction with, or control, a control valve
  • The customer wants a single technical partner for several parts of the tank installation
  • The problem may be caused by factors other than the sensor itself
  • Materials and process connections must be evaluated across the entire installation

KLINGER DENMARK vs. VEGA: Two Different Technical Approaches

VEGA is a highly specialised supplier of level and pressure measurement technology, with particular strength in radar-based solutions.

For many dedicated level measurement projects, the company will therefore be a natural starting point.

KLINGER DENMARK’s strength lies in its broader understanding of process engineering.

When the level sensor is just one component in an installation involving pumps, valves, gaskets, seals and control systems, KLINGER DENMARK can incorporate more of these elements into a single technical solution.

The choice between the two companies is therefore not about identifying a good supplier and a bad one.

It is about selecting the approach that best matches the application.

If the primary requirement is specialised level measurement instrumentation, VEGA has a strong position. However, if the instrumentation must form part of a broader process installation in which valves and sealing solutions also play an important role, KLINGER DENMARK may be the more comprehensive technical partner.
