Point of Use (POU) meters are built to give a submetering solution for all those properties that can't be submetered by conventional submeters because of plumbing designs that bring multiple pipes in the apartment or office (stacked risers). The meters were created specifically for stacked riser plumbing configurations typically seen in properties that employ a central boiler to provide domestic hot water.
Within a typical installation really small flow meters are installed inconspicuously on each hot & cold outlet towards the shower/tub, toilet, sink, dish-washer and garments washer. With regards to the manufacturer the flow meters either have a very transmitter integrated or are linked to an interface board/ transmitter. The transmitters report usage information to some central Processing computer that therefore forwards the usage information to a billing center where bills might be printed and shipped to the finish user.
Equipment and installation costs are typically higher that traditional systems however the payback continues to be usually just one year. When deciding on a POU meter, a principal consideration should be how the meters might be read by Automated Reading System (AMR). This enables the property owner to select from many billing companies and tie the property owner to equipment that may simply be read by a few companies.
Submetering is proven by numerous studies to lessen usage up to 39%. Although POU meters happen to be readily available for over decade they haven't been popular alternatives. With all the current fascination with green solutions and also the ever rising water and sewer costs properties that in the past couldn't be traditionally metered have become installing POU meters and benefitting through the same type of usage reductions that properties with conventional plumbing have realized for years. Since roughly 50% of apartments and 90% of offices utilize stacked riser plumbing the advantages of submetering with POU meters have barely been touched.
