Traditional methods often involve manually tuned piston pumps with check valves. Verification of flow, by changing the stroke length, is often carried out empirically with stop-watch and graduated gauges. This traditional approach virtually makes it impossible to actively compensate to changing process conditions, such as temperature changes (caused by day/night). The result may be the worst-case flow setting, increasing chemical use, environmental impact and also cause over-dosing (!) of chemicals under normal operation conditions.
Accurate flow control
Accurate flow control enables cost effective applications with less environmental impact.
High accuracy and high turndown ratio is achieved based on pure mass measurement with mini Cori Flow. This mass flow meter can also directly control valves and pumps by on-board PID control and can be further optimized with PLC and HMI control extending both performance and flexibility.
Coriolis dosing system
Our Coriolis dosing system approach, with digital communication, 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 such as on-board status alarms enabling; steering monitoring, density alarm changes, single or multi point totalisation for costs calculations, empty tank alarm, and pump protection shut down.
Bronkhorst has been supporting field applications and R&D research projects with extensive know how on low flow fluid handling. The ongoing research for even more environmental friendly solutions, such as biodegradable based inhibitors, is gladly supported by us.
Corrosion inhibitors are also used in other kind of industries, e.g. the public water systems.
