Bronkhorst CORI-FLOW mass flow meter for dosing of corrosion inhibitors

Click2Contact

In industrial applications, especially in the chemical, process and oil and gas industry, corrosion can be a real challenge. These types of industries are coping with demanding environmental and process conditions in production and operation. Prevention or control of corrosion by inhibiting often proves to be an economic solution.

A corrosion inhibitor system will add small concentrations of (bio)chemicals into the process. 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.

Using a low-flow control system containing a Bronkhorst CORI-FLOW (mini) mass flow meter can help to manage the dosage of corrosion inhibitors. The flow meter is designed to achieve high accuracy and high turndown ratio based on pure mass flow measurement. It can directly control valves and pumps by onboard PID control and can be further optimised with PLC and HMI control extending both performance and flexibility.

Bronkhorst’s Coriolis dosing system approach enables real-time monitoring, control and logging of injection rates. This allows online checking of flow rates and instantaneous resetting of the required flow rate. Asset management and preventive maintenance are supported with several active diagnostics.
