Ensuring correct pipe diameter entry is crucial for accurate separation distance in configuration.
Verify gel pad covers are removed and sensors are correctly positioned on the pipe with screws fully removed.
Excessive air in the system or an empty pipe can lead to insufficient conditions for meter operation.
Ensure ultrasonic grease or gel pads are correctly installed on the sensor block for proper contact.
Corroded pipe surfaces or internal deposits can distort signals and affect meter performance.
Install unit where fluid flows uniformly, away from disturbances like bends, valves, or pumps.
System isolated or pump off may show flow if zero-flow offset wasn't set during installation.
Low flow rates may show no reading; lowering zero cut-off can help, but check for noise/instability.
Surface roughness of galvanised pipes can affect accuracy and prevent valid flow signal acquisition.
Fluid concentration variations in mixtures like Glycol/Water or Ethanol/Water can cause errors.
Composite pipes show limited compatibility due to signal propagation issues, dimming or misdirection.
