Laboratory Products 53 Precise solutions for low flow liquid measurement
Low-flow measurement is increasingly prevalent across various industries. Yet, as flow rates decrease, the task of controlling and measuring them becomes progressively more challenging. This poses a significant obstacle for users and flow sensor manufacturers alike in their search for cost-effective and reliable flow measuring technologies. While there isn’t a standardized definition for ‘low flow’ concerning fluidics handling, these applications face distinct challenges compared to larger flows. The minimal volume of liquid involved makes low-flow systems highly sensitive, amplifying concerns about flow stability and performance. Even minor disruptions in process or environmental conditions can significantly affect flow stability in low-flow scenarios. In the markets where Titan Enterprises operates, low flow rates are considered to be those below 50 ml/min, with many customers seeking flow rates ranging from 2 to 20 ml/min. Neil Hannay, Senior R&D Engineer at Titan Enterprises, noted: “We are observing a significant rise in the demand for low flow measurement technologies, fuelled by various industries shifting towards transporting highly concentrated liquids that are later diluted at the point of use. This transition results in substantial savings on transportation and storage expenses, while also yielding positive environmental benefits.” From cleaning fluid additives to beer or soda syrups and flavourings, chemical additives for oil and fuel, paint pigments, or drug administration, the use of low-flow flowmeters is essential. They ensure precise dosing of these concentrated fluids at the end of the process, facilitating accurate dispensing for the correct dilution. As mentioned, measuring low flow presents a challenging application to address. The energy available in low liquid flow is often inadequate to drive most mechanical flowmeters to provide linear results. Electronic flow meters, on the other hand, may face limitations such as sensitivity, zero drift, and slow response times. This analysis covers five types of flow meter - Ultrasonic, Turbine, Oval Gear, Thermal, and Coriolis - and assesses their suitability for low flow measurement. Selecting the most appropriate high-precision flow sensor for your application is crucial, as flowmeters can often be the most constraining element of a low flow fluidic system. Neil stated: “We recognise a robust market demand for low flow meters, and we are presently collaborating with two international OEMs to devise a solution for measuring ultra-low flows leveraging our oval gear technology and miniaturised gears.”

Vapourtec’s E-Series flow chemistry system has achieved a significant milestone with its 300th installation worldwide, marking a decade of innovation and progress in the field of flow chemistry.
Established as the leading entry-level flow chemistry system over the past ten years, the E-Series has been instrumental in numerous research breakthroughs, featuring in over 250 peer-reviewed publications. Notable citations include contributions to studies such as ‘Continuous Flow-Processing of Organometallic Reagents Using an Advanced Peristaltic Pumping System and the Telescoped Flow Synthesis of (E/Z) Tamoxifen’ (P. R. D. Murray, D. L. Browne, J. C. Pastre, C. Butters, D. Guthrie, S. V. Ley, Org. Proc. Res. Dev. 2013, 17, 1192−1208) and ‘C(sp3 )–H functionalizations of light hydrocarbons using decatungstate photocatalysis in flow’ (G. Laudadio, Y. Deng, K. van der Wal, D. Ravelli, M. Nuño, M. Fagnoni, D. Guthrie, Y. Sun, T. Noël, Science 2020, 369, 92-96) [2].
Currently utilised in 20 countries and adopted by major pharmaceutical companies worldwide, the E-Series has significantly impacted both academia and industry. Reflecting on its journey, Vapourtec founder and MD Duncan Guthrie remarked on its transformative role in introducing a continuous process approach to chemists globally.
With plans to launch new software later this year to enhance system capabilities, Vapourtec remains committed to advancing flow chemistry technology. The E-Series, available in four standard configurations, offers precise control over reaction parameters and a modular design adaptable to specific needs.
Guthrie emphasised the system’s robustness and ease of use, which have contributed to its widespread adoption. Looking ahead, Vapourtec aims to integrate machine learning and AI into the E-Series, enabling automated reactions, data logging, and seamless integration with other laboratory equipment.
As the E-Series enters its second decade, it continues to shape the future of flow chemistry, expanding possibilities and driving innovation in research and development.
