Contrec 515 Series with CB01 application is a blending controller measuring the blending flow an in main and process line using frequency flow inputs.
The blending controller can operate in PRESET, ON-OFF (manual) and RELEASE mode of operation. The latest mode allows for easier tuning of the control loop.
The main and process flows are used to determine the net volume flow. The operator can view the ratio of totals as well as the ratio of flow rates. The control of the process flow is via a digital control valve. The flowrate deadband and control responsiveness can be adjusted to reduce wear on valves.
