Installation Procedures
Begin by selecting a level mounting surface within the instrument panel. Position the Micro Motion 5700 transmitter so that inlet and outlet ports face the fluid flow direction. Secure the unit with the supplied mounting brackets, tightening screws to the manufacturer’s torque specifications.
Connect the 24 VDC power supply to the power inlet, observing correct polarity. Use a dedicated power cable rated for the operating environment and route it away from high‑temperature or high‑vibration zones. Ground the transmitter chassis to the facility grounding system through the grounding terminal to prevent electrostatic buildup.
Attach the fluid inlet and outlet fittings to the transmitter’s NEMA 4X connectors. Verify compatibility with the process fluid’s pressure rating and temperature range. Tighten all fittings to the specified torque to avoid leaks. Install pressure relief valves upstream and downstream as required by process safety standards.
For data communication, connect the Ethernet/IP or FOUNDATION Fieldbus cable to the data port. If using Ethernet, configure the IP address via the webserver or a temporary console connection. Ensure the network switch supports the required bandwidth and that the transmitter’s MAC address is registered in the network management system.
After all connections are made, power on the transmitter. The display will show a self‑test sequence; verify that all status indicators read normal and that the display shows a green status light. If any error codes appear, consult the diagnostic section of the manual. Once the unit passes the self‑test, proceed to the initial calibration in the next section.
Apply a pressure of 1.5 bar above normal operating pressure to test for leaks. If the test is successful, the transmitter is ready for commissioning! All steps must be performed by qualified personnel.
Calibration and Characterization
Use the transmitter display to check meter status. Follow the step‑by‑step meter characterization sequence, recording mass and volume flow values. Configure output parameters, then save settings. Verify accuracy with a reference and vol standard.
Meter Status Check
Before any calibration or operation, the user must verify the meter’s health and readiness. The Micro Motion 5700 transmitter offers a dedicated “Meter Status” screen accessible from the main menu. This screen displays a concise list of diagnostic flags, each accompanied by a numeric code and a brief description. The status screen is refreshed automatically every 10 seconds, ensuring that any transient faults are captured promptly.
Key indicators include:
- Temperature: Shows the internal sensor reading in °C. Values outside the range 0 °C–80 °C trigger a warning.
- Pressure: Displays the inlet pressure in bar. A pressure below 1 bar or above 10 bar sets a fault flag.
- Signal Integrity: Indicates the quality of the Coriolis signal. A low signal‑to‑noise ratio (SNR) below 30 dB is flagged.
- Communication: Reports Ethernet and FOUNDATION Fieldbus link status. A disconnected link shows as “Link Down.”
- Calibration: Shows the last calibration date and the number of calibration cycles performed. If the cycle count exceeds the manufacturer’s recommendation, a maintenance alert appears.
To interpret the status, the operator should cross‑reference the numeric codes with the troubleshooting section of the manual. For example, code 0x01 indicates a “Temperature out of range” condition, while 0x0A denotes a “Signal integrity loss.” The display also offers a “Clear” button that resets all temporary fault flags after the underlying issue has been resolved.
In addition to the visual display, the transmitter can export status data via the integrated webserver. By navigating to the “Operations” tab and selecting “Export Status,” the user can download a CSV file containing timestamped readings for each diagnostic parameter. This feature is invaluable for trend analysis and preventive maintenance planning.
Regular meter status checks are essential for ensuring measurement accuracy, preventing data loss, and extending the transmitter’s service life. Operators should perform these checks at the start of each shift and whenever a significant change in process conditions is detected.
Meter Characterization Steps
The Micro Motion 5700 transmitter requires a systematic characterization to ensure accurate Coriolis flow measurement; Select “Characterize” from the main menu, enter expected flow range, fluid density, and temperature. The transmitter then initiates calibration pulses automatically. The display shows progress and fault flags. The user can review data before proceeding. Quickly. Now.
During the cycle, the transmitter records mass flow, volume flow, and temperature at several points. The user can pause to verify readings or adjust the flow range. After the cycle, correction coefficients are calculated and applied to the flow algorithm. The transmitter logs each measurement point to internal memory for post‑run analysis. The exported data can be reviewed on a PC.
To verify accuracy, run a “Check” command that compares the transmitter’s output to a reference standard. A deviation below 0.5 % is acceptable. If the deviation exceeds the threshold, repeat the characterization or adjust parameters. Once the check passes, select “Save” to store the new coefficients permanently. The webserver can export calibration data for archival. The exported data can be reviewed on a PC.
It is recommended to perform a full characterization at least once every 12 months or after major maintenance. The manual also covers troubleshooting for signal drift, temperature instability, and communication errors. Regular calibration ensures compliance with industry standards. It supports ISO 9001.
