Dosing Flow Meter Operation Guide

Last updated 1 month ago

Dosing refers to the industry-standard function of controlled volumetric addition. This process involves opening a control valve until the target flow volume is reached, at which point the valve closes. In certain applications, repeated dosing of the same volume is required. In industrial settings, this is commonly achieved using a PLC in conjunction with a control valve and a flow meter. If the control valve’s operating current is compatible (refer to the electrical specifications section of this manual), the dosing function of this flow meter can be used directly with the valve. This eliminates the need for additional PLC programming while still achieving precise volumetric dosing.

Dosing Operation Procedure

  1. Enable the Dosing Function: Navigate to the C03 menu on the control panel and activate the dosing function to ensure the system is in standby mode.

  2. Set the Target Dosing Volume: Enter the desired dosing volume in C04, which determines when the dosing process completes.

  3. Configure the Reset Time Unit: In C05, specify the waiting time before resetting the accumulated total. The time unit is in seconds.

  4. Set OCT to Dosing Mode: Switch the controller’s OCT mode to dosing, enabling it to drive the control valve accordingly.

  5. Configure the Main Screen (H09): Set the main screen to batch dosing mode for easier operation and real-time monitoring of dosing parameters.

  6. Start Dosing: Return to the main screen and initiate the dosing process. Once the accumulated flow reaches the target value, OCT status will change from open circuit to closed circuit. The main screen will start a countdown, displaying the remaining time in the center of the top row. While the countdown is active, if flow continues, the accumulated dosing value on the screen will keep updating.

  7. End of Countdown: When the countdown finishes, the accumulated dosing value automatically resets to zero. Simultaneously, OCT status changes from closed circuit back to open circuit.

Important Notes

Due to valve switching delays and control signal transmission delays, there may be discrepancies between the measured total volume and the set target. Several factors can contribute to these deviations, including: "Smaller target dosing volumes", "Higher flow rates", "The distance between the valve", flow meter, and final container These factors may cause the actual dosed volume to differ from the target value. For precise dosing, select an appropriate pipe diameter and piping configuration. Additionally, it is recommended to test and adjust the calibration factor before actual operation. At the end of the countdown, the accumulated dosing value will automatically reset to zero, and the OCT status will switch from closed circuit back to open circuit.
