Deliver Better Systems
Ultrasonic flow measurement is a growing industry which offers non-intrusive, high accuracy measurements in across a range of applications. PZFlex can simulate ultrasonic meter performance under the influence of complex flow fields, and is used in diverse applications from anemometers to custody meters.
The flow module allows a background flow field to be applied to the simulation which will influence acoustic wave propagation. This allows the full effect of flow on device output to be assessed. Effects such as beam distortion, Doppler Effect, and shifts in arrival time can be accurately predicted.
Multi path meters
Many modern flow meters use two or more sound paths in order to reduce sensitivity to flow separation and turbulence. PZFlex allows designers to optimise the arrangement of these paths to reject these parasitic effects and obtain a true measurements of average velocity.
Full meter performance
PZFlex has the power to simulate entire flow meters and pipe sections, not just individual components. By integrating transducers into the simulation designers can predict what signals will appear on the meter for a given flow condition.
Swirl & turbulence
Complex flow fields can have unexpected effects on velocity measurements. Proximity to bends, the presence of a conditioning plate and the transducer cavities themselves can all have an effect on the accuracy of the meter. The flow module allows CFD generated flow fields to be imported, allowing these effects to be fully considered.
Many devices utilise frequency shifts caused the Doppler Effect as an accurate means of measuring flow velocity. PZFlex’s combination of a time domain solver with background flow fully considers these effects, allowing accurate frequency deviations to be calculated form a single model.
In most practical meter designs crosstalk through the meter body or pipe can contribute significantly to unwanted parasitic signals. PZFlex’s ability to consider the realistic meter geometries and transducer mounting allows these effects to be analysed and ultimately minimised.
PZFlex is used in a wide variety of industrial sensing applications from process monitoring to thickness gauges. Its ability to rapidly simulate acoustically large structures, and include electromechanically coupling make it well suited to analysing sensors which are closely coupled to their surrounding environment. By simulating the sensor and the structure in a single model PZFlex allows designers a unique insight into how their system behaves.
Ultrasound can be used to both monitor and accelerate chemical reactions by passing sound through the reagents inside a test cell. PZFlex has helped researchers fine tune these processes, by predicting acoustic beam patterns, received signals and sensor performance.
PZFlex gets its name from its electromechanical solver which allows it to rapidly carry out time domain analysis on piezoelectric materials. With full support for external circuits, PZFlex can predict how electrical loading affects transducer performance.
Simulate complete linear and 2D matrix probes. Analyse electrical and mechanical crosstalk, directivity, electrical impedance, beamforming and more. Advanced solvers enable large transducer models to be solved in hours rather than days.
PZFlex’s ability to mesh structures in exceptional detail makes the simulation of complex structures both easy and accurate. STEP and IGES formats can be imported directly, with other formats available through optional pre-processors.
From 1-3 to 2-2 configurations PZFlex has been the benchmark in piezocomposite simulation since its inception. PZFlex has all of the tools required for you to optimize your microstructure, select the correct materials and meet even the toughest customer specifications.
Time domain simulations are well suited to broadband analysis of sensors and transducers. By running a single time domain model full performance information across a wide spectrum can be generated. PZFlex’s efficient explicit solvers allow this to be carried out efficiently, quickly getting designs the answers they need.
