ATTENTION

The default engineering units for volumetric flow rate is cubic meters per hour and tonnes per hour is the default engineering units for mass flow rate.

The URV changes automatically to compensate for any changes in the LRV and maintain the present span (URV – LRV).

If you must change both the LRV and URV, always change the LRV first.
