Sizing and Meter Selection

Flowmetrix Technical Services is an industry leader in sizing and meter selection. This service includes;

• Reviewing utilities’ historical meter volumetric data, assessing highest volumetric users vs. size, outlining apparent losses through improper meter sizing vs. demand analysis,

• Performing field studies to validate the actual meter size vs. customer flow demand profiles, against facility fixtures values, and reassessment of apparent losses due to size,

• Perform cost benefit analysis of an appropriate meter sizing and selection program for customer base


Why is meter sizing important?

Meter sizing allows the water purveyor to capture all revenue possibly while balancing the potential pressure losses du to higher flows.

A meter undersized will create a pressure loss while an over sized meter will not have this issue; will under-read due to low flow demand.

P.S. Remember a improper sized meter might be accurate but not suitable for the flow demands, losing revenue, or creating pressure issues in the system for the end user.

Can meter sizing be done in the office - after the fact?

Meter sizing can be done after the fact.  Using the customer account information and meter size along with meter specifications (AWWA or other), will assist in prediction of whether the meter is under/over-sized.

However, to ensure the meter is sized properly, a field flow demand profiling study will need to be done to overlay against the predicted assumptions

.  These values will yield a potential benefit in higher revenues, if the desktop office review is done properly.

Why is meter selection important?

Meter selection is paramount and should be done in consideration with meter sizing.

If the meter selection does not satisfy the customer demand applications, the overall accuracy might not yield the best performance , and hence lower revenue.

In addition, poor meter performance would only suggest that a premature replacement would result losing any investment benefit upon initial meter changeout.
