Why Is Your Vortex Flow Meter Showing Incorrect Readings?

AUTO Instrument has recently manufactured a batch of vortex flow meters equipped with temperature compensation features, and has summarized several common issues customers face when using these devices. These issues mainly revolve around pulse signal pressure-temperature compensation output.

1. No Flow Display

• Incorrect Secondary Instrument Settings: Ensure proper settings, including pressure-temperature auto compensation.

• Damaged Circuit Board: Check frequency output with a multimeter to verify the board’s condition.

2. Inaccurate Flow Display

• Pressure and Temperature Mismatch: Ensure correct pressure range settings and accurate temperature readings for consistent flow output.

• Instability in Instantaneous Flow: Consider instrument stability and interference issues if flow readings fluctuate widely.

• Empty Running: This may be caused by pipeline vibrations or electromagnetic interference; solutions include reinforcing the pipeline or adding filters.

3. Inaccurate Pressure and Temperature Readings

Incorrect pressure and temperature range settings are often the cause of measurement inaccuracies. Users should verify and adjust these settings for accurate flow readings.

4. Empty Running Phenomenon

This issue occurs when the flow meter registers flow while not in use. It’s often due to excessive sensitivity, pipeline vibrations, or electromagnetic interference. Reducing sensitivity or reinforcing the pipeline can help resolve it.
