Vortex flow meters have become a widely adopted flow measurement technology in process industries due to their non-intrusive nature and versatile characteristics. However, proper installation, commissioning and troubleshooting is crucial to ensure accurate measurement.
Installation
- Piping requirements– Ensure straight pipe runs of 10x & 5x upstream and downstream pipe diameters.
- Orientation– Mount vertically for gases/steam, horizontally for liquids with flow direction upwards.
- End connections– Flanges should be aligned concentrically without piping stress.
- Sensor positioning– Mount sensor away from plant disturbances for reliability.
Commissioning
- Flow checks– Verify working fluid, pressures, temperatures meet specifications.
- Signal validation– Compare meter reading to calibrated reference for accuracy.
- Documentation– Record commissioning data, calibration constants and circuit outputs.
Troubleshooting
- No output– Check power, cabling, obstructions and transducer integrity.
- Erratic output– Potential causes may be disturbances, sensitivity, Reynolds number, fouling.
For any issues, consult the vortex flow meter manual or manufacturer. Proper handling ensures long-term reliability of this robust, versatile flow technology.
