The Bronkhorst FLEXI-FLOW™ Compact Mass Flow Meters and Controllers


Bronkhorst's FLEXI-FLOW™ combines the benefits of a novel through-chip sensor with established by-pass technology. The small thermal mass flow meters and controllers are 35% smaller than typical instruments, making them the smallest on the market at flow rates of up to 20 ln/min. The devices provide highly steady flow control and quick control, with settling times of less than 150 ms, thanks to the innovative sensor method.
  • Multi-parameter measurement: flow, temperature, and pressure in one instrument
  • Simple and secure connection through Bluetooth and comprehensive App
  • Superior accuracy through onboard gas database and real time conversions
  • NAMUR status indication keeps you informed about your process
  • Adaptable to many applications through wide dynamic range of measurement and control
  • Dynamic flow ranges up to 1:1000
Contact Swanson Flo for more information about the performance, application, and ordering of the Bronkhorst FLEXI-FLOW™ compact mass flow meter and controller.

Accurate Dosing of Corrosion Inhibitors Greatly Improves Corrosion Prevention and Extends Pipeline Life

Pipe Corrosion
Accurate dosing of corrosion inhibitors in industrial applications, especially in the chemical, process and oil and gas industry can be a real challenge. These industries cope with demanding environmental and process conditions in production and operation. In oil and gas, it is common that wells produce other products that are likely to cause corrosion, such as water and carbon dioxide. Pipelines are required to transport oil and gas products from the well, sometimes over long distances. Even though they are designed to last for decades, corrosion processes are responsible for degradation and significant losses. It is clear that the best way to combat corrosion economically is through prevention using chemical inhibitors.

A corrosion inhibitor system will add small concentrations of (bio)chemicals into the process which form a film on the interior surface of the pipe or vessel, preventing corrosive attack. The effectiveness of an inhibitor system greatly depends on the correct injection amount, and can be influenced by the environmental and process conditions; so accuracy is crucial here. A properly applied chemical corrosion inhibitor system is very effective in lowering corrosion rates, with the potential to reduce corrosion rates up to 99%.

The key in determining the overall rate of corrosion over the life of a pipeline is determined by the proportion of time for which the corrosion inhibitor is available, and the correct concentration. In order to accurately assess the availability of corrosion inhibitor, it is necessary to have some means of accurately measuring the dosage of inhibitor being injected.

CORI-FLOWUsing a low flow control system containing a mass flow controller (MFC) allows for very accurate corrosion inhibitor dosing. High accuracy and high turndown ratio is achieved based on pure mass flow measurement with this type of flow meter. A device such as the Bronkhorst (mini) CORI-FLOW mass flow controller can directly control valves and pumps via it's on-board PID controller, and be further optimized with ancillary PLC and HMI controls, extending both performance and flexibility.

The application of chemical corrosion inhibitors can significantly reduce the rate of corrosion  and using a dosing system with an integrated MFC (such as the Bronkhorst (mini) CORI-FLOW) enables real-time monitoring, control and logging of injection rates. This allows online checking of flow rates and instantaneous re-setting of the required flow rate. Asset management and preventive maintenance is supported with several active diagnostics.
