Current Trends and Innovations in Test and Measurement Instruments
Published on : Friday 05-07-2024
With the advent of advanced digitalisation, the complexity of T&M devices has increased, making ease of operation paramount, says Wout van 't Wel.
The test and measurement instruments industry is undergoing significant advancements, particularly in the realm of mass flow meters and controllers. A prominent trend is the integration of multiple sensors within these devices, allowing for more comprehensive and precise measurements. These sensors, coupled with intelligent firmware, enable real-time data processing and advanced analytics, resulting in highly accurate and reliable performance.
Modern mass flow meters and controllers are becoming increasingly compact and user-friendly, facilitating easier integration into various applications. The use of digital communication protocols, such as EtherCAT, Modbus, and Profibus, enhances connectivity and interoperability with other industrial systems. This digital transformation is crucial for industries requiring stringent control over gas and liquid flows, such as semiconductor manufacturing, biotechnology, and chemical processing.
Moreover, innovations in materials and microfabrication techniques have led to improved durability and sensitivity of these instruments. Advanced calibration techniques ensure that these devices maintain their accuracy over extended periods, reducing the need for frequent recalibrations.
Influence of regulations and standards
Regulations and standards play a pivotal role in shaping the design and manufacture of mass flow meters and controllers. Compliance with established guidelines ensures that these instruments are reliable, safe, and effective for industrial applications. For instance, the FLEXI-FLOW Compact series incorporates NAMUR NE107 status indication, which uses colored LED lighting to inform users about the operational status of their processes. NAMUR, an international user association focused on automation technology and digitalisation in process industries, sets stringent standards that enhance the reliability and user-friendliness of process instruments.
By adhering to NAMUR NE107 and other relevant standards, manufacturers of mass flow meters and controllers can provide users with clear, immediate feedback on process conditions, facilitating quick responses to any issues. This adherence not only boosts the operational efficiency and safety of industrial processes but also ensures compatibility and interoperability with other equipment. Overall, regulations and standards such as those from NAMUR drive innovation and continuous improvement in the design and functionality of mass flow meters and controllers, ensuring they meet the high expectations of modern industrial applications.
Ensuring accuracy and reliability against environmental concerns
Bronkhorst ensures the accuracy and reliability of their mass flow meters and controllers through a robust approach that prioritises both precision and
environmental responsibility. Obtaining environmental certifications such as RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) is a fundamental part of their strategy. These certifications affirm that Bronkhorst’s instruments comply with stringent environmental regulations, minimising the use of hazardous substances and ensuring safe and sustainable operation.
Moreover, Bronkhorst’s commitment to accurate conversion and calibration processes plays a crucial role in enhancing the performance of their mass flow meters and controllers. By meticulously calibrating their instruments with the aid of the extensive FLUIDAT database (1800 fluids) and FLUICAL calibration software, Bronkhorst eliminates the need for using valuable or rare gases and liquids. This not only conserves these resources but also reduces environmental impact by preventing unnecessary emissions and waste.
Additionally, the precision in measurement offered by Bronkhorst’s devices ensures optimal efficiency in various applications, from industrial processes to research settings. This accuracy translates into better control over material usage and energy consumption, further underscoring Bronkhorst’s dedication to environmental responsibility and sustainability. Through these measures, Bronkhorst maintains a high standard of reliability while actively contributing to environmental conservation.
Data management and utilisation
Test and measurement instruments, such as mass flow meters and controllers, play a crucial role in data management and utilisation through advanced predictive maintenance and diagnostic functions. These devices are equipped with data logging capabilities that track a variety of parameters including flow rate, temperature, pressure, and valve status. By continuously recording and analysing this data, mass flow meters and controllers can predict the health status of the instruments and the overall condition of the processes they monitor.
Predictive maintenance is facilitated by identifying trends and patterns in the recorded data, allowing for the detection of potential issues before they lead to equipment failure. For instance, deviations from normal flow rates or unexpected temperature changes can signal impending problems. Additionally, multiple configurable alarms can be set to notify users of these anomalies in real-time, ensuring prompt action can be taken to mitigate risks and avoid downtime.
These advanced data management features not only enhance the reliability and efficiency of mass flow meters and controllers but also optimise the processes they control. By leveraging the collected data, users can make informed decisions, improve process control, and ensure the longevity of their instruments, ultimately leading to cost savings and increased operational efficiency.
Preparing for a career in test and measurement

Aspiring engineers and technologists aiming for a career in Test and Measurement, particularly in the realm of mass flow meters and controllers, should prioritise the human interface aspects of these instruments. With the advent of advanced digitalisation, the complexity of these devices has increased, making ease of operation paramount. Engineers must ensure that new instruments not only deliver high-quality performance but also offer intuitive user interfaces. This balance is crucial for enhancing user experience and efficiency in various applications, from industrial processes to laboratory experiments.
For instance, the FLEXI-FLOW Compact series is a prime example of this approach. These devices are designed to combine precise mass flow control with user-friendly features. They offer accurate measurements and control capabilities while being easy to operate and aesthetically pleasing. This not only simplifies the workflow for operators but also reduces the likelihood of user error, ultimately improving the reliability and effectiveness of the measurement process.
By embracing these advancements and addressing the evolving needs of the market, Bronkhorst High-Tech continues to lead the way in gas flow control technology, ensuring that their products remain at the forefront of innovation and efficiency.
