Tuesday 22 June 2021, 15:00 – 16:00 CEST, online webinar
On 22 June, the consortium working on EMPIR project ‘Metrology for real-world domestic water metering’ (17IND13, Metrowamet) will host its second online seminar for utilisers and manufacturers - as well as advisory board members.
The seminar will be presented by Sarah Jones from TÜV SÜD National Engineering Laboratory.
Topics covered will include:
- Are water meters as accurate under unsteady flows such as those generated by washing machines or toilets?
- Does water quality influence meter accuracy?
- How well can water meters detect leakage?
There are accuracy requirements for domestic water meters, which are currently tested under steady flow conditions. But are these requirements still met by meters during the unsteady flows experienced in the real world? If not, how much does this affect the measurement of total consumption? If there is a significant effect, then either the water company is not billing for all the water used or the customer is being overcharged. This also impacts on water companies’ leakage calculations.
Are the available meter types affected differently by water quality? Should water companies be aware of this when selecting which meter type to install? Domestic leakage is both a cost to the consumer and a potential risk of damage to property which should be identified as soon as possible. How smart are ‘smart meters’ at detecting leakage in real time? Can this be improved with more intelligent algorithms?
To answer these questions, project participants have built experimental facilities and developed protocols to test domestic water meters under fluctuating flows, low flows and with varying water qualities. Commercially-available domestic meter types have been included in the test programme and the results have been used to create a ‘virtual flow meter’ model. The implications of this work for national and international standards for meter test and certification procedures are currently being evaluated.
