Drag Force Flow (DFF) Sensor A robust and reliable solution for in-line, real-time measurement of flow forces in industrial processing operations and research. Lenterra Inline Rheometer (LIR) A process analytical technology (PAT) - real-time measurement of critical process parameters (CPP) such as viscosity in food processing or granule densification and wet mass consistency in pharmaceutical wet granulation - based on a thin Drag Force Flow (DFF) probe placed within the processing equipment. RealShear™ Wall Shear Stress Sensor Lenterra’s RealShear™ sensor mounts flush with a pipe or vessel wall enabling direct measurement of wall shear stress of flowing liquids. The wall shear stress (WSS) measurement is taken without the need to disrupt the process enabling scale-up and control of blenders and mixers as well as monitoring corrosion in pipes and tanks. Process Analytical Technology: In-Line Flow Force Measurement System DFF and RealShear™ sensors provide a robust and reliable solution for process monitoring and control in rheologically complex fluids and powders. Such a Process Analytical Technology (PAT) is vital for a variety of industries such as pharmaceutical, food, biotech and others. Knowledge Base DFF sensor proved to be a useful tool for high shear wet granulation monitoring. It enables differentiation between close formulations, determination of the granulation end-point and scale-up. It provides in-line real-time quality control for powder, food and other products.

In the lubricant, paint and ink industries where most of the fluids used are non-Newtonian with varying viscosities, dynamic control of fluid viscosity is required to produce a quality finished product.

Lenterra’s in-line PAT provides reliable fluid flow sensor measurement that not only helps produce a final product with the correct properties but also increases the longevity of the processing equipment by blocking valves and presses when viscosity is not optimal.

In the oil and gas industries, accurate fluid flow measurement plays a vital role in production optimization.

Where periodic well tests can take months to reveal production problems such as mechanical failures, water breakthroughs and casing damage, Lenterra’s sensors can provide timely, real-time flow measurements – heading off potential problems before they can become a threat to operations.
