Contrec 515 Batch Ratio Controller (BR01)

The Contrec 515 BR01 is a batch and ratio controller designed for delivering specific quantities at set ratios using volumetric frequency inputs. It can operate in both preset and on-off modes for batch control, while flow control can be configured for local (manual) operation or PI loop mode.

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 via communications. Users can quickly access frequently used preset values directly from the front panel, provided they have the necessary authorization.

The PI control of the process flow is managed through a 4-20mA proportional valve. 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.

Before we quote this, we would normally check the flowmeter’s pulse output type, the batch quantities and ratios you need, and the valve or actuator you plan to control. Hope this helps.

FunctionBatch and ratio controller for delivering set quantities at set ratios from a volumetric frequency input. Supports PRESET and ON-OFF batch control modes, with flow control in local (manual) or PI loop mode.
InputsFrequency input from a volumetric flowmeter – millivolt, reed switch, Namur proximity, or open collector pulse.
DisplayBacklit alphanumeric LCD showing flow rate, flow rate deviation, and batch totals.
Accuracy0.05% of full scale @ 20°C, 0.1% typical across full temperature range.
Outputs4-20mA proportional valve control output with wind-up protection, deadband, output hold, and adjustable ramp time; 2x isolated pulse outputs (200mA/30Vdc) or 4-20mA analogue retransmission, 0.05% accuracy; 2 standard relays (3A max), 2 optional.
