Main Screen Data Interpretation

Instantaneous Flow Rate and Error Margin

The maximum possible measurement error for this flow meter is: ±0.5% of Full Scale (F.S.) + ±2.5% of Observed Reading (O.R.).

This means that the relationship between measured values and maximum possible error will vary depending on the flow velocity, as illustrated in the reference chart.

Flow Velocity

The flow velocity shown on this screen represents the fluid speed inside the tee section of the flow meter. In most cases, this value is slightly higher than the velocity in an equivalent straight pipe of the same diameter.

Totalised Flow and Historical Data

The totalised flow display will continue accumulating until it is manually reset. The maximum count for totalised flow is 999,999,999 litres.
