FINDING THE FLOW
James Lees from UK Flowtechnik explores the various process industry applications for fl owmeters
N
on-invasive fl owmeters off er a host of advantages, making them an essential tool for numerous industries
requiring precise fl uid measurement. Alongside traditional contact style fl owmeters such as gear (circular, helical and oval), axial turbine, pelton wheel, and variable area fl owmeters, there are magnetic inductive fl owmeters. These non-invasive technologies deliver accuracy and reliability, addressing the challenges of modern industrial applications.
CORIOLIS FLOWMETERS IN THE POLYURETHANE FOAM INDUSTRY In the polyurethane foam industry, Coriolis fl owmeters have become indispensable for the precise measurement of raw materials, specifi cally isocyanates and polyols. These components are critical to foam production, where consistent quality, density, and performance are paramount. Coriolis fl owmeters excel in this application by providing instant mass fl ow measurements that are unaff ected by variations in temperature, pressure, or fl uid viscosity. This capability ensures accurate chemical dosing and maintains the correct stoichiometric ratio in foam formulations. Furthermore, the ability of these fl owmeters to measure both mass fl ow and density enables real- time monitoring and adjustments, signifi cantly enhancing product quality and minimising waste.

well suited for polyurethane production owing to their ability to handle a wide range of fl uids, including viscous and abrasive substances. The inherent accuracy and reliability of these fl owmeters contribute to superior process control, improved eff iciency, and reduced material costs. Manufacturers benefi t from consistent foam quality while meeting safety and regulatory requirements, underscoring the transformative impact of this technology on the industry.
MAGNETIC INDUCTIVE FLOWMETERS IN THE BEVERAGE INDUSTRY Similarly, magnetic inductive fl owmeters (often referred to as mag meters), have proven invaluable in the beverage industry. These fl owmeters off er precise, non-intrusive measurement of conductive fl uids such as water, juices, and soft drinks. Their utility extends to critical processes like mixing, batching, and fi lling, where precision is key. Mag meters operate using Faraday’s Law of Induction, generating a magnetic fi eld that induces a voltage as the conductive liquid fl ows through it. This voltage correlates directly to the fl ow rate, ensuring highly accurate and repeatable measurements. One of the primary advantages of
mag meters is their design, which eliminates moving parts. This reduces maintenance requirements and the risk of contamination, a crucial
consideration in food and beverage production, where hygiene and safety are non-negotiable. Additionally, mag meters cause minimal pressure drop, maintaining consistent fl ow rates and optimising process eff iciency. Their ability to handle varying fl uid viscosities and temperatures makes them versatile enough for a wide range of beverages, including carbonated drinks, fruit juices, and syrups. These features make magnetic fl owmeters indispensable for ensuring product quality and streamlining production processes in the beverage sector.
CONCLUSION The applications of non-invasive fl owmeter technologies extend far beyond these two examples, demonstrating their versatility and value across various industries. By adopting Coriolis and magnetic inductive fl owmeters, businesses can achieve improved accuracy, eff iciency, and reliability while reducing costs and ensuring compliance with stringent industry standards.
