Suggested remedy
• Allow the flowmeter to warm up (approximately 30
seconds). The error should disappear once the
flowmeter is ready for normal operation.
• If alarm does not clear, make sure that the sensor is
completely full or completely empty.
• Check the sensor circuitry. See Section 11.25.
• If alarm appears during a transmitter zero, ensure
that there is no flow through the sensor, then retry.
• Cycle power to the flowmeter, then retry.
• If appropriate, restore the factory zero to return the
flowmeter to operation.
• Ensure that there is no flow through the sensor, then
retry.
• Cycle power to the flowmeter, then retry.
• If appropriate, restore the factory zero to return the
flowmeter to operation.
• Ensure that there is no flow through the sensor, then
retry.
• Cycle power to the flowmeter, then retry.
• If appropriate, restore the factory zero to return the
flowmeter to operation.
• Remove or reduce sources of electromechanical
noise, then retry. Sources of noise include:
- Mechanical pumps
- Pipe stress at sensor
- Electrical interference
- Vibration effects from nearby machinery
• Cycle power to the flowmeter, then retry.
• If appropriate, restore the factory zero to return the
flowmeter to operation.
• Cycle power to the flowmeter.
• The transmitter might need service. Contact Micro
Motion. See Section 11.3.
• Check the sensor RTD circuitry. See Section 11.25.
• Verify that process temperature is within range of
sensor and transmitter.
• If the problem persists, contact Micro Motion. See
Section 11.3.
• Check the sensor RTD circuitry. See Section 11.25.
• Verify that process temperature is within range of
sensor and transmitter.
• If the problem persists, contact Micro Motion. See
Section 11.3.
• Check the characterization. Specifically, verify the
FCF and K1 values. See Section 6.2.
• Check the characterization. Specifically, verify the
FCF and K1 values. See Section 6.2.
