The Contrec 515 CR01 is a reliable single loop process controller designed for measuring volume flow in both main and process lines using frequency flow inputs. This advanced chemical injection control system can operate in various modes, including local (manual), loop, ratio, or blend mode. It features a user-friendly tuning menu that helps you easily set the Proportional Band and Integral Time Values for the PI control algorithm.
By monitoring the main and process flows, the Contrec 515 CR01 accurately calculates the net volume flow. Operators can view the current ratio and deviation, and if authorized, they can adjust the controlling setpoint directly from the main menu.
The PI control of the process flow is managed through a 4-20mA proportional valve or industrial dosing pump controller. This system includes integral wind-up protection, and you can program the deadband and output ramp time to minimize wear on valves and actuators, ensuring smooth and bumpless operation.
