The Contrec 515 BF03 is a reliable batching flow controller designed for delivering specific quantities at set flow rates using a mass frequency input. This chemical injection control system can operate in either preset or on-off modes for batch control, while flow control can be configured for local (manual) operation or PI loop mode.
This system offers operators a clear local display that shows flow rate deviations, and it can be integrated into more automated systems for remote control. Authorized users can quickly access frequently used preset values directly from the front panel, enhancing usability.
The PI control of the process flow is managed through a 4-20mA proportional valve or industrial dosing pump controller. It features built-in wind-up protection, a deadband, output hold, and adjustable ramp time, all of which can be programmed to minimize wear on valves and actuators, ensuring smooth and bumpless operation.
