8KBB Mass Flow Meter HART Version Manual Overview
8KBB mass flow meter is a high-precision flow measurement instrument that supports the HART communication protocol. This manual is intended to help users correctly install, configure, and operate the flow meter. Through the HART interface, users can remotely read parameters such as flow rate, density, and temperature, and perform configuration settings.

HART Communication Configuration Steps
Hardware Connection
- Ensure that the 8KBB mass flow meter is properly powered (usually 24VDC).
- Use a HART communicator or a HART-supported PLC/DCS to connect to the flow meter via the 4-20mA loop.
- Check whether the loop resistance meets the HART communication requirements (minimum 250Ω).
Software Settings
- Turn on the HART communicator and enter online mode.
- Select the device type as "8KBB mass flow meter".
- According to the menu prompts, set parameters such as tag number, range, and damping time.
- Save the configuration and exit.

Installation and Maintenance Points
Installation Precautions
- The installation location should avoid strong vibration and electromagnetic interference.
- Ensure that the fluid direction is consistent with the flow meter arrow.
- For gas measurement, vertical installation is recommended to facilitate condensate discharge.
Daily Maintenance
- Regularly check whether the wiring terminals are loose.
- Use a HART communicator to read self-diagnostic information to detect faults in time.
- Perform calibration once a year to ensure measurement accuracy.
Common Problems and Solutions
- HART communication failure: Check the loop resistance and power supply voltage.
- Abnormal flow display: Confirm whether the pipe is full and check the parameter settings.
- Zero drift: Perform zero calibration, ensuring it is done when there is no flow.
