Welcome to VEGA’s new technologies. Here you’ll find innovations that were developed with two things especially in mind: you and the optimal functioning of your systems.
Our current innovations for your future:
- Level radar gauges VEGAPULS series 60
- Microwave barrier VEGAMIP
- Differential pressure transmitter VEGADIF
- Radiometric detector PROTRAC for level, density and flow measurement
- Level measurement with guided microwave VEGAFLEX
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:
- bulk solids
In point level detection, a point level switch detects when a certain predefined level is reached. Such a device is employed when it is not necessary to measure every possible intermediate level, as is the case with continuous level measurement. A switching command starts or stops filling equipment such as conveyors or pumps. Point level switches outputting a binary signal can be integrated into a process control system.
Point level detection systems can be used in liquids, pastes, powders or coarse bulk solids.
Typical applications for level switches are:
- minimum or maximum detection
- leak detection
- overfill protection
Pressure measuring techniques can be used to measure not only process or differential pressure, but also level, volume, density or mass flow in all areas of process technology.
The measuring ranges of pressure transmitters start at a few mbar and extend to extreme pressures up to 1,000 bar. Different measuring cells are used in these pressure instruments.
VEGA pressure transmitters deliver high-precision readings in
The proportion of solid matter in a liquid is determined with the help of density measurement.
Typical applications in the process industry are the measurement of acid and lye concentrations, the mixture density of abrasive or sticky liquids and the solid matter content of sludges and slurries.
VEGA uses two different physical measuring principles for density measurement
- Differential pressure
Flow rate measuring instruments measure the amount of substance that flows through a pipe cross-section per time unit. The measured quantity is outputted as mass or volume. Typical flow rate applications measure gases, vapours and aggressive or viscous liquids in pipelines as well as bulk solids on conveyor belts.
VEGA uses two different physical measuring principles for flow rate measurement:
- Differential pressure
Industrial processes are highly automated nowadays. To ensure smooth operation, measuring instruments are employed to deliver a steady flow of up-to-date, objective information about the process to the control technology. Various hardware components as well as signal conditioning software process and integrate the measurement data.
They convert the analogue or digital signals from the measuring instruments into information, i.e. measured values, that are displayed on indicating instruments or fed directly into the control system.
Electromagnetic Flow Meters
Electromagnetic flowmeters, also known as magnetic flow meters or simply mag meters, offer a number of practical advantages over traditional flow metering technologies which employ mechanical measuring techniques.
The simple construction of our electromagnetic flow meters is the key to these advantages. A SmartMeasurement magnetic flow meter does not contain any moving parts, rotating gears or turbines, or bearings. Instead, it relies on two electrodes to measure the density of the induced magnetic field that results from an electrically conductive fluid, such as water, flowing through a pipe. The density of the magnetic field is directly proportional to the fluid velocity of the flowing liquid.

High Precision Mag Meter Technology
Specific advantages that our magnetic flow meter technology provides include:
- High accuracy
- Low cost
- Little to no pressure loss
- Readings that are unaffected by changes in density or viscosity
- No susceptibility to bearing wear or other mechanical wear-and-tear issues
Because the only wetted components in a SmartMeasurement electromagnetic flow meter are the electrodes and the liner, these components can be fabricated from a variety of materials to make the mag meter compatible with virtually any electrically conductive fluid, including aggressive acids.
The only real limitation of the electromagnetic flow meter is that the measured fluid media must be electrically conductive (> 5μS/cm). Non-conductive fluids, such as oil and other petroleum-based fluids, cannot be measured with mag meter technology.

Ultrasonic Flow Meters
What Is An Ultrasonic Flow Meter?
Ultrasonic flow meters offer a number of advantages over other flow measuring technologies. The most distinct of these advantages is the non-invasive nature of ultrasonic measuring technique: fluid flow can be measured by clamping a pair of transducers onto the outside of the pipe without contacting the measured fluid.
This installation method, unique among flow metering technologies, allows ultrasonic flow meters to be used in applications where the process cannot be shut down and/or the pipe cannot be cut for installation. Clamp on flow meters also cause no pressure drop, suffer no mechanical wear and tear, allow for bidirectional measurement, and provide the ability to pass unlimited solids past the meter without damage.
Fluid velocity is measured by sending an ultrasonic pulse from an upstream transducer to a downstream transducer and back again. The measured difference in the amount of time that each pulse takes to traverse the pipe is directly proportional to the mean fluid velocity. SmartMeasurement’s ultrasonic flowmeters use this measured velocity to calculate the liquid flow rate based on user-entered information about the process application.
For a more detailed discussion of our ultrasonic flowmeter’s principles of operation, please visit our Ultrasonic Measuring Principle page.
SmartMeasurement’s Ultrasonic Flow Meters
Vortex Measuring Overview
Vortex meters are one of the few flow measuring technologies that can measure all three phases of a fluid; gas, liquid and steam. This technology provides a cost-effective, reliable, low maintenance solution for many flow measurement applications. It has no moving parts, therefore no routine maintenance or cleaning is required. The vortex flowmeter can measure also measure wet and/or dirty gases. Vortex flow sensing technology relies on measuring the number of vortex pulses generated by a bluff body immersed in the flow stream. A bluff body is machined inside the vortex flow meter; as flow pass through this bluff body, vortices are generated in either side of the bluff body. The flow rate can be determined by measuring the number of vortices. For a more detailed discussion of the principle of operation, please go to: http://www.smartmeasurement.com/flow-meters/vortex/measuring-principle.
The design of SmartmeasurementTM‘ s ALVT vortex flowmeter allows for extremely wide turndowns while maintaining an almost unlimited upper end as well as a high pressure rating. The ALVT can be configured in inline styles with both NPT and flanged connections or as an insertion meter with optional hot-tapped ball valve mounting for installation and/or removal of the instrument without shutting down the process. Our ALVT-MASS multivariable vortex flow meter incorporates an RTD temperature sensor and a solid state pressure transducer that allows the mass flow rate of steam, gases and liquids to be measured and displayed directly on the meter’s display. Please see the Vortex flowmeter matrix below to view all available options.
Turbine Measuring Flow Meters
Turbine Flowmeters measure volumetric flow, where flow passing through the tube is measured as a function of the mean velocity of the streaming fluid. Turbine flow meters may be configured to measure either gas or liquid flow rates. A low mass turbine wheel carried axially in the tube is rotated by the fluid; the RPM of the turbine wheel is directly proportional to the mean fluid velocity within the tube. For a more detailed discussion of the principle of operation please go to: http://www.smartmeasurement.com/flow-meters/turbine/measuring-principle
SmartmeasurementTM’ s ALTM turbine flow meters come in sizes ranging from 15-300mm (½” to 12”) and feature a wide turn-down with minimum uncertainty and a very repeatable output. The ALTM is excellent for precise measurement of instantaneous flow of low-viscosity fluids such as tap and demineralized water, fuels, liquefied gases, light fuel oils, solvents, and pharmaceutical fluids. Please see the turbine flowmeter matrix below to select the best meter for your application.
Coriolis Mass Flow Meters
Energy Flow Meters
Energy Flow Meters
Energy Flow Meters Overview: Flowmeters that perform energy measurement consist of a flowmeter with integrated temperature measurement to measure both supply and return temperature and then calculate thermal energy in units of BTUs. In addition to providing direct BTU measurement, these flowmeters also can display liquid flow rate and process temperature. The temperature measurement is typically achieved via use of precision RTD elements while the liquid flow rate measurement can be done with an electromagnetic flowmeter, a turbine flowmeter, an ultrasonic flowmeter, or a variety of other flowmeter technologies.
SmartMeasurementTM offers Energy flow meters that employ ultrasonic and magnetic flow measurement technologies in order to provide users with a degree of flexibility in selecting the best product for their specific application. For non-intrusive energy measurement, the ALSONIC-EG provides highly accurate energy measurement for applications including treated water with low electrical conductivity and buildings where the air-conditioning can’t be turned off to install the meter. The ALSONIC-EG enables retrofitting of transducers under pressure with a clamp-on non-intrusive installation method. For applications where there are particulates or bubbles entrained in the fluid, the ALMAG-EG, which makes use of a Mag Meter to measure the liquid flow, is the instrument of choice. All SmartMeasurement BTU Flowmeters are available with optional Mbus, BACNET, MODBUS, and Profibus communication protocols.
Thermal Flow Meters
Thermal meters measure gas mass flow directly without the need for additional need pressure, temperature and/or density monitoring. They operate either by introducing a known amount of heat into the flowing stream and measuring an associated temperature change, or by maintaining a probe at a constant temperature and measuring the energy required to do so. Thermal mass flowmeters include two temperature sensors and an electric heater between them. The heater can protrude into the fluid stream or may be external to the pipe. By eliminating temperature changes in the process, any heat transfer within the flow stream is directly proportional to its mass flow. For a more complete description of thermal mass flow technologies please go to; http://www.smartmeasurement.com/flow-meters/thermal/measuring-principle
Thermal meters have no moving parts, wide turn-downs (up to 1000:1), a range from 0.02 meters per second (4 feet per minute) to over 200 mps (40,000 fpm), and very low pressure drop. SmartmeasurementTM, s ATMF series of thermal mass flowmeters can be used with pipe diameters ranging from 8mm (¼”) to up to several meters using our multi-sensor configurations. Process connections can be flanged, threaded, or hot-tapped ball valve. SmartmeasurementTM’ s ATMF Series Thermal Mass Flowmeters feature available integral style or remote mount electronics, an easy-to-read OLED display, and a unique calibration self-check technique that allows for field verification of the factory calibration. Please see the Thermal Product Matrix below to select the best configuration for your specific application.
Variable Area Measuring
Variable area flowmeters are simple and versatile devices that operate at a relatively constant pressure drop and measure the flow of liquids, gases, and steam. Variable Area (VA) flowmeters make use of a float, piston or vane placed inside a flow body, which changes position in response to changes in flow rate of the measure fluid media. The position of the float, piston or vane provides a direct visual indication of flow rate. Either the force of gravity or a spring is used to return the float to its resting position when the flow lessens. For a more detailed discussion of the principle of operation, please go to: http://www.smartmeasurement.com/flow-meters/variable-area/measuring-principle
SmartmeasurementTM’ s ALVAMT Variable Area flow meter is of the spring operated variety, which allows the meter to be mounted in either horizontal or vertical orientations. The ALVAMT makes use of rugged, metal tube construction making it ideal for high pressure, high temperature and other demanding flow applications where safety is a concern. Features include mechanical readouts for use in locations where power is not available or in hazardous areas; analog and digital LCD local display options, multiple process connection options; several different materials of construction for metering of aggressive fluids and corrosion resistance; and HART enabled 4-20mA output to allow for remote monitoring and control.
Positive Displacement Flow Meters
Positive Displacement Flowmeters, which employ one of the oldest-known flow measurement techniques, are widely used in industry and have one of the largest install bases of any flow meter technology. Positive Displacement Flowmeters feature two precisely machined rotating members inside a measuring chamber of known volume which may be used to accurately determine volumetric flow rate as a function of the rotors' velocity. A more detailed discussion of the principle of operation can be found at:http://www.smartmeasurement.com/flow-meters/positive-displacement/measuring-principle
The advantages that the Positive Displacement Flowmeter provides over other technologies are numerous. These advantages include high accuracy (up to 0.1% of reading), excellent repeatability, wide turndown ratios, high temperature operation, high viscosity operation, no upstream or downstream straight pipe requirement, the ability to be used with mechanical registers which require no electrical power, and readings which are immune to changes in viscosity. This combination of features and advantages makes the PD meter an ideal choice for applications that can be found in many different industries including food & beverage, paint & coatings, oil & gas, and fluid power.
Differential Pressure Flowmeters
Open Channel Flow Meters
The SE series operating principle is simple. A unit is usually located through a bin wall at the top, middle or low level of a bin. During normal operation (no material present) a synchronous motor rotates the paddle at 1 RPM. When this paddle rotation is impeded by material, surroanding the paddle, motor will stall and cause the Micro switch to change state. (indicating an alarm or control) Product Introduction.
The purpose of the rotary paddle level switch is to detect the presence of solid/powdery material in most kinds of tanks, bins and containers. The unit is usually located through a bin wall at the top, middle or low level of a bin. During normal operation (no material present) a synchronous motor rotates the paddle at RPM. When this paddle rotation is impeded by material, surrounding the paddle, motor will stall and cause the Micro-switch to change state (indicating an alarm or control).
