The more robust data will allow residents to be contacted quickly if the information suggests a leak in their pipes.
The proposal follows early September's announcement by Glenview municipal water authority securing of a deal with Sensus for replacement of smart water meters that were registering false readings.
The village in the suburb of Chicago,approved an offer from Sensus to replace 1,500 iPerl smart water meters installed between 2012 and 30 July, 2015, as well as swapping the water authority's pre-existing stock of water meters, reported Metering & Smart Energy International.
Under the deal, Sensus will also verify that all new meters were manufactured in 2015, and extend its warranty from 10 years to 15 years.
The deal followed an admission from Sensus that manufacturing problems in 2014 had resulted in the iPerl smart water meters making false readings in July 2015.
