Sizing

The minimum meter that meets the specified continuous flow should be chosen. Do not oversize, in case of borderline select the smaller meter. However, make sure that the pressure drop does not get too high. Short term overload refers to less than 1 hour per day or at most 100 hours over its in-use life.

Accessories and options

Maintenance and spare parts

Control and auditing should be performed by a meter workshop that is accredited as an inspection unit.

Marking
