The Contrec 515 BR01 is a reliable batching ratio controller designed for delivering specific quantities at set ratios using volumetric frequency inputs. This chemical injection control system can operate in both preset and on-off modes, while also offering various loop control modes for effective flow measurement.
This system provides operators with a clear local display that shows flow rate deviations, and it can be integrated into more automated systems for remote control. Users can quickly access frequently used preset values directly from the front panel, provided they have the necessary authorization.
The process flow is controlled using a PI control method with a 4-20mA proportional valve or industrial dosing pump controller. The system includes built-in wind-up protection, a deadband feature, output hold, and adjustable ramp times. These features help minimize wear on valves and actuators, ensuring smooth and bumpless operation.
