What to do if Onicon Measuring Instruments sensor cable connections are incorrect or loose?
If you suspect the sensor cable connections on your Onicon Measuring Instruments are incorrect or loose, refer to the connections diagram. Disconnect and reconnect the sensor cables, ensuring they are properly inserted into the terminals and tightened.
What to do if Onicon Measuring Instruments show erratic measurements?
If you observe erratic measurements on your Onicon Measuring Instruments, first set the Calibration / Damping to 5% and use the Setup / Tare function with zero flow. Also, ensure the triax cable shield is properly connected to ground and that the correct power input ground connection is in place. Double-check the sensor separation distance. Finally, adjust the Calibration Menu / Min Flow setting.
What to do if Onicon Measuring Instruments meter reading is higher than expected due to electrical noise?
If your Onicon Measuring Instruments' meter reading is higher than expected and you suspect electrical noise, ensure the triax cable sensor shield is properly grounded and that the correct power input ground connection is established. Also, double-check the sensor separation distance.
Why Onicon Measuring Instruments show lower flow rate than expected?
If the flow rate is lower than expected on your Onicon Measuring Instruments, investigate the pump and valves. You may also compare the velocity with an alternate instrument.
Why Onicon Measuring Instruments show higher flow rate than expected?
If the flow rate is higher than expected on your Onicon Measuring Instruments, examine the pump and valves. Comparing the velocity with an alternate instrument can also help diagnose the issue.
What to do if Onicon Measuring Instruments are affected by variable speed drive interference?
To mitigate variable speed drive interference with your Onicon Measuring Instruments, follow the drive manufacturer's wiring and grounding instructions. Additionally, relocate the flow meter electronics, sensor, and wiring away from the VSD.
What to do if Onicon Measuring Instruments show calibration error?
If your Onicon Measuring Instruments display a calibration error, review the calibration menu, checking the pipe dimensions and fluid selection/fluid velocity settings.
What to do if Onicon Measuring Instruments meter reading is higher than expected due to calibration error?
If your Onicon Measuring Instruments' meter reading is higher than expected due to a calibration error, review the calibration menu, paying close attention to the pipe dimensions and fluid selection/fluid velocity settings.
What to do if Onicon Measuring Instruments show 'NO ECHO' due to sensor connections?
If your Onicon Measuring Instruments display a 'NO ECHO' indication related to sensor connections, ensure the triax cable sensor shield is properly grounded and that the triax cable is correctly connected to the transducers.
What to do if Onicon Measuring Instruments sensors are not mounted properly?
If the sensors of your Onicon Measuring Instruments are not mounted to the pipe or are improperly mounted, apply coupling compound and mount the sensors to the pipe with proper sensor spacing.
