The measurement technique of LaserDopplerVelocimetry (LDV) is one of the most frequently applied modern measurement techniques in fluid mechanics to perform accurate local flow velocity measurements, which exhibits the advantage of a very high local and temporal resolution. Our technical department offers excellent conditions to perform such measurements (LDV).

Measures in full crosssection. • continuous speed measurement of solids in metal pipes • measurement directly in the conveying stream/entrained flow • measurement completely independent of material • sensor is made accordingly to the existing pipe diameter • measurement without product contact

Especially designed for continuous measurement of velocity of solids and particles such as granulates, powders and dusts, which are transported in free fall or in pneumatic transport. Uses triboelectric correlation technology. • plugin sensor for easy retrofit • continuous speed measurement of solids • measurement directly in the conveying stream • material independent measurement

Flue gas flowmeter for continuous measurement of gas velocity, temperature and pressure in exhaust gas ducts (chimneys or flue pipes).

For the generation and production of a spray the knowledge of information like the desired droplet size and its distribution is of fundamental importance. In order to characterise a spray correctly, one has to know the droplet size distribution of the droplets, which were generated out of a given liquid. In many applications it is desired to produce very small droplets. For the design and lay out of inhalers for example, it is necessary to achieve droplet sizes not larger than approximately 10 μm to be absorbed by the lungs. When one designs an atomisation nozzle in view of the desired droplet size distribution, one has to make sure via measurements, that the nozzle is really able the produce the expected droplet size distribution within an acceptable uncertainty range. Besides the droplet size distribution, the droplet velocity is an important parameter since it is a measure of the droplet momentum.

The particle image velocimetry (PIV) is an optical noninvasive working flow velocity measurement method. The flow field is made visible by introducing into the fluid small buoyancy neutral particles – the so called tracers. The particle flow then is illuminated with the aid of a light sheet and recorded at two defined different times within a small time interval with a digital camera. Because the particle move within this time interval with the flow, one can calculate the particles velocity by knowing its path between the two moments of illumination. The result is a velocity vector field of the flow. Here, we assume that the particles are small and follow the flow without any slip. Compared to local methods like LaserDopplerVelocimetry (LDV) with the ParticleImageVelocimetry one can reconstruct a whole flow region An extension of ParticleImageVelocimetry is the combination of PIV with thermometry (PIV/T).

The Series AFS Air Flow Sensor is a differential pressure air velocity sensor designed to measure average air velocities in VAV terminal units and HVAC ductwork. It has an aero-dynamic elliptical shape resulting in a minimum pressure drop and amplified differential pressure signals which allow accurate measurement of air velocities from 300 fpm to 5000 fpm (1.5 m/s to 20 m/s). It includes multiple sensing points aligned in line grooves to measure total and static pressure. It is easy to install and cost effective. Series AFS Airflow Sensors are perfect for VAV Retrofits. The AFS is a differential pressure air velocity sensor designed to measure average air velocities in VAV terminal units and HVAC ductwork.

The Series JFM-P FloSen® Airflow Meassuring Probes provide accurate, repeatable measurement of air movement in HVAC ducts. Its patented elliptically-shaped sensor design with improved aerodynamic characteristics outperforms more traditional devices, and overcomes loss of accuracy caused by fluid separation at the sensor body. It is designed to maintain a constant parallel airflow pattern over the static sensing ports for more accurate, steady signals under all duct conditions. The elimination of separation results in a stabilized static pressure signal, helping to eliminate “hunting” during fan control. FloSen® Airflow Probes utilize a unique in-line groove for total pressure sensing and dual ports for static pressure sensing which produces a higher differential pressure for very low velocity measurements. The total and static pressure measuring points are distributed for equal-area averaging of flows resulting in improved accuracy and reliability.

The Series VTP Multi Range Air Velocity Transmitter can simultaneously display and output Air Velocity, Temperature and Pressure (optional). This is the first product to combine all 3 variables in one transmitter making the VTP an exceptional option for multi-variable measuring. The VTP utilizes an industrial 316 Stainless Steel armored RTD sensor as the thermal air velocity measuring component. Using a fully protected 316 SS sensor drastically extends the life of the air velocity sensor and also makes it insensitive to water, dust or corrosion. The VTP comes standard with a LCD and can simultaneously display air velocity, temperature, and pressure. The VTP is easily configured or adjusted in the field with the digital display and keypad. The Air Velocity Range and Pressure Range are both field adjustable as well as units of measure. Other adjustable parameters include signal dampening and low velocity cut off point.

CoriSENS is a rotation rate sensor for measuring angular velocity ω. It detects rotational movements using a MEMS gyroscope.

When using vibration transmitters, the vibration evaluation and the fault switch-off are outsourced, i.e. the alarm thresholds are parameterised in a separate evaluation unit or in a PLC that can record the trend development. Transmitters are current loop powered and output a normalised current signal corresponding to the vibration, which is then scaled in the system controller. The vibration transmitters of the 64x series are available with different measuring ranges and quantities (vibration velocity according to ISO 10816, vibration acceleration and vibration displacement, among others) that are related to the respective application. — Vibration transmitter with current output corresponding to the peak value of the vibration velocity — Measuring range 0 ... 12.7 mm/s — Output range 4 ... 20 mA — Frequency range 3 ... 1,000 Hz — 2-pin connection socket on top For an individual offer, please contact us directly.
