Hovány, Lajos (Faculty of Civil Engineering, Subotica (Serbia))
Testings made from April 2011 through June 2012 proved, a water meter (class B, with 20 mm rated diameter) registers water consumption with error values lower than the allowed ones only if the same flow through water meter lasts at least 1 hour (water meter reading accuracy is one litre). Using a household storage tank with installed water meter at the storage tank inlet pipe could be a solution to this problem. A thermally insulated storage tank, 60 litres in volume was made for measuring water consumption in a bachelor’s flat in Subotica (consumption measurements were made in August and September 2012). Measurement proved that, without changing the temperature range of the mains water, water consumption measurement by water meter is ensured in the bachelor’s flat.
