Check out the broad range of Levelflex devices for guided wave radar applications and click on the button below.

Guided radar level measurement is well suited to liquids and bulk solids. The surface condition of the medium is of minor importance due to the safe guidance of the reflected waves. Turbulent liquid surfaces or foam formation as well as different angled surfaces or outflow funnels, as the occur in bulk solids, do not influence the measurement. Guided radar is also the first choice for interface measurement.

Guided radar measurement: Measuring Principle

Levelflex works with high-frequency radar pulses which are emitted and guided along the probe. As the pulse meets the medium surface, part of the emitted pulse is reflected due to a change of the dc value (relative dielectric constant). The Time-of-Flight between pulse launching and receiving is measured and analyzed by the instrument and constitutes a direct measure for the distance between the process connection and the product surface.

Benefits of Guided Wave Radar Measurement

  • Reliable measurement: Unaffected by medium surfaces and tank obstacles or baffles
  • Additional measuring safety through End-of-Probe (EoP) evaluation
  • Safe measurement also during filling

Various transmitters for continuous level measurement and switches for point level detection are available. The measurement of interface is also possible. The measuring principle is proven in millions of applications.

Capacitance measurement: Measuring Principle

The principle of capacitive level measurement is based on the capacitance change of a capacitor. The probe and the tank wall form a capacitor whose capacitance is dependent on the amount of product in the tank: An empty tank has a lower, a filled tank a higher capacitance.

Vibration Switches

Vibronic point level detection

Point level switches in liquids and solids

Vibronic point level detection offers safe overfill prevention in liquids and bulk solids in every industry. The second line of defense guarantees the highest degree of safety and availability of the switches. Liquiphant stands for reliable switching unaffected by: changing media properties, turbulences, foam, vibrations or build-up. In silos containing fine-grained or powdery solids Soliphant is the perfect match.

Vibronic devices perfectly fit for numerous liquid applications from simple operational point level detection (min. and max. control), certified leakage monitoring and overfill prevention through to protective equipment in plant parts subject so Safety Integrity Levels (SIL 2/3). For applications in powdery or lumpy bulk solids the vibronic devices can also be used in hazardous areas, typically in primaries, the chemical or the food industry.

Vibronic point level detection: Measuring Principle

For point level detection in liquids a sensor in form of a tuning fork is excited at its resonant frequency. The drive works piezoelectrically. The oscillating frequency changes as the fork enters the medium. The change is analyzed and translated into a switching signal.

In solids a one-rod sensor is excited at its resonant frequency. The drive works piezoelectrically. The amplitude changes as the fork enters the medium. The change is also analyzed and translated into a switching signa


Radiometric Level Measurement

Continuous level measurement and point level detection in liquids and bulk solids with Gamma devices

Radiometric level measurement with source container and Gammapilot provide reliable measurement values where other measuring principles can not be used anymore due to extreme process conditions or because of mechanical, geometric or construction conditions. Gamma devices are made for non-contact point level detection, continuous level, interface and density measurement in liquids, solids, suspensions or sludges. Check out the broad range of radiometric devices and click on the button below.

With radiometric measurement devices four measuring tasks (continuous level, point level, density and interface) can be solved, even under extreme process conditions. The radiation of the gamma source container is emitted almost unattenuated in one direction only, and is damped in all other directions. This guarantees highest safety for the personnel and a reliable measurement.

Radiometric measurement: Measuring Principle

The gamma source, a cesium or cobalt isotope, emits gamma radiation which is attenuated as it passes through materials. The measuring effect results from the absorption of radiation by the product to be measured which is caused by level changes. The measuring system consists of a source, a source container and a compact transmitter as a receiver.

Servo level measurement

Continuous liquid level measurement in custody transfer and inventory control applications

Servo tank gauging instruments offer high precision measurement for liquid level, interface and density applications. The devices fulfill the exact demands of tank inventory management and loss control and are optimized in regards of total cost saving and safe operation.

Servo level devices as tank gauging instruments are used for custody transfer and inventory control applications with NMi- and PTB-approvals and meet the requirements according to OIML R85 and API 3.1B. Proservo is especially suited for high accuracy custody transfer measurement in crude oil, gasoline, diesel, petrochemicals and chemicals.

Servo level measurement: Measuring Principle

A small displacer is accurately positioned in a liquid medium using a servo motor. The displacer is then suspended on a measuring wire which is wound onto a finely grooved drum housing. When the displacer is lowered and touches a liquid, the weight of the displacer is reduced by liquid buoyancy force. As a result, torque in the magnetic coupling changes, which is measured by 5 sets of Hall sensors.

Differential Pressure

Continuous level, flow and differential pressure measurement

Differential pressure transmitters with piezoresistive pressure sensors and welded metallic membrane or electronic dp or diaphragm seal is used mostly in the process industry. Deltabar offers continuous level measurement in liquids as well as volume or mass flow measurement using primary elements. It is also possible to do filter monitoring with the differential pressure transmitter. Check out the broad range of Deltabar devices and click on the button below.

Pressure Gauge Products

Beside the devices with silicon or diaphragm seal for differential pressure, level, dp flow measurement, Deltabar electronic dp is a differential pressure system combining two sensor modules and one transmitter. In level applications, the high pressure sensor (HP) measures the hydrostatic pressure. The low pressure sensor (LP) measures the head pressure. The level or differential pressure is calculated in the transmitter using these two digital values.

Differential pressure measurement: Measuring Principle

Silicon cell: The operating pressure deflects the process isolating diaphragm and a fill fluid transfers the pressure to a resistance bridge (semiconductor technology). The pressure-dependent change in the bridge output voltage is measured and evaluated.

Diaphragm seal: The operating pressure acts on the process isolating diaphragm of the diaphragm seal and is transferred to the process isolating diaphragm of the sensor by a fill fluid.


Universal dp transmitter for flow, level or filter applications
With diaphragm seal process temperatures from -70 up to +400°C (-94 to +752°F)
The electronic differential pressure system eliminates traditional mechanical issues resulting in greater process availability and reliability. Also safety risks are minimized with the electronic dp system architecture and design

Versatile and economical flow measurement of gases and liquids up to a nominal diameter DN 4000

Using ultrasonic waves, the flow volume of a wide variety of gases and liquids can be measured reliably – independent of electrical conductivity, pressure, temperature, or viscosity.
In applications that require traceable and guaranteed accuracy, inline ultrasonic sensors are preferred for use. Clamp-on ultrasonic sensors, on the other hand, are installed on the outer wall of the pipe and thus also enable temporary measurements or a retrofitting.

Clamp-on sensors

  • For retrofitted installation without interrupting the process
  • Aggressive fluids can be measured without any problems, even under high pressure
  • Suitable for pipes made of plastic, steel, cast iron composite materials (lined/unlined)
  • For pipe diameters up to DN 4000 (156″)

In-line sensors

  • Guaranteed accuracy thanks to traceable factory calibration
  • Robust industrial design in accordance with ASME and EN
  • Short inlet runs
  • For pipelines up to DN 300 (12″)

Ultrasonic flow measuring principle

Swimming against the flow requires more power and more time than swimming with the flow. This simple fact is the basis for ultrasonic flow measurement according to the “differential transit time” method: This method uses two sensors, set opposite each other in the measuring tube. Each sensor can alternately transmit and receive ultrasonic signals, while simultaneously measuring the signal transit time.

As soon as the fluid in the tube starts to flow, the signals are accelerated in the direction of flow but delayed in the opposite direction. The differential transit time, measured by the two sensors, is directly proportional to the flow rate.


  • Measurement independent of pressure, density, temperature, conductivity, and viscosity (for homogeneous fluids)
  • Free pipe cross-section, no pressure loss
  • No moving parts, minimum maintenance and upkeep
  • Long service life, no abrasion or corrosion from the fluid
  • In-line or clamp-on design for stationary or temporary flow measurements
