Contrec 515-BF01 Dual Stage Batch & Flow Controller

The Contrec 515 BF01 is a reliable batching flow controller designed for delivering specific quantities at set flow rates using a volumetric frequency input. This chemical injection control system can operate in either preset or on-off modes, while the flow control can be adjusted to local (manual) or PI loop mode.

This system offers operators a clear local display, showing flow rate deviations, and can be integrated into more automated systems for remote control. Authorized users can quickly access frequently used preset values directly from the front panel for convenience.

The PI control of the process flow is managed through a 4-20mA proportional valve or industrial dosing pump controller. It features built-in windup protection, a deadband, output hold, and programmable ramp time to minimize wear on valves and actuators, ensuring smooth and bumpless operation.
