Pipe ID Gauge
Internal Pipe Diameter Gauge. Accurate internal diameter and offset distance measurement on-site reduces errors in flow calculation.
Errors in either the cross-sectional area of the pipe (calculated from pipe internal diameter) or the insertion point (1/2D, 1/8D or 7/8D) can lead to significant errors in flow calculation.
Therefore, in situations where the pipe specification is uncertain, or there is any doubt about the precise values of the internal diameter and offset distance, it is recommended to use a Pipe Diameter Gauge to actually measure these parameters on-site.
