A general answer is NO. This would depend on the benefit or predicted return on the investment to conduct such calibration practices. Working within a greater study incorporating meter selection and changeout, meter sizing, meter verification and meter accuracy programs work together to form a complete metering program.
No, it is not required if you are willing to accept the numbers as is. Meter calibration is part of a meter verification program. Meter calibration is conducted when a meter falls outside an acceptable level of tolerance within a certain level of confidence. Meter calibration ensures all flows are measured to the best truth … Read more
The main categories are Supply Input Volume, Authorized Consumption, Water Losses, Revenue Water and Non-revenue Water. The sub-categories are Billed Authorized Consumption, Un-billed Authorized Consumption, Apparent Losses and Real Losses.
A Balance is a report outlining all components of a water system accounting for 100% of the water used after production, by means of operational use, theft and inaccuracies, demand and real losses. An Audit is reviewing the information obtained that forms the balance providing clarity of numbers providing 95% confidence against each component in … Read more
The meter size is only one of the basic inputs to review and therefore, I can not say what the minimum size should be. However, it might be said, review your larger customer base first and then review smaller sizes second. Other inputs that should be considered is volume and cost of meters ownership to … Read more
There isn’t a common denominator for this answer. Each meter principle should be considered for every meter application reviewing both low and high flow characteristics, and pressure losses. Understanding your clients, demand profile and inventory, use of building, seasonal uses, etc. would be some of the items to consider when determining the best meter for … Read more
Meter sizing allows the water purveyor to capture all revenue possibly while balancing the potential pressure losses du to higher flows. An undersized meter will create a pressure loss, while an oversized meter will not have this issue, rather it will under-read due to low flow demand. P.S. Remember an improper sized meter might be … Read more
Yes. Verification allows the owner to realize performance status across an expected operating range or industry standard like AWWA. The testing results identified in a sample of meters predict the best time for meter replacement program rather than accepting a standard that does not know your meters, your customers, etc.
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 … Read more
