  • Contrec 515 Series with CR01 application is a single loop process controller measuring the volume flow an in main and process line using frequency flow inputs. It can operate in local (manual), loop, ratio or blend mode and has a tuning menu to easily determine the Proportional Band and Integral Time Values used in the PI control algorithm.

    The main and process flows are used to determine the net volume flow. The operator can view the actual ratio and deviation and has the ability to change the controlling setpoint directly from the main menu if access has been authorised.

    The PI control of the process flow is via a 4-20mA proportional valve or pump controller. It has integral wind-up protection and a deadband and output ramp time can be programmed to reduce wear on valves and actuators and provide for bumpless operation.

    • Tailored for volumetric frequency flow input
    • Uses PI Loop Control
    • Pump demand contact
    • Selection of various control modes
    • “Flushing” available via external logic signal
    • Allows for cascade trim control when ratio of totals is required
    • Allows for non-linear correction
    • Selection of second language and user tags
    • RTC logging with over 1000 entries
    • Selectable protocols on serial ports including Modbus RTU and Printer output
    • Backlit display with LCD backup
