“…The meter is an opportunity for high resolution flow rate sensing. The display unit of a meter can be mechanical or electronic, but the measurement assembly often has a rotating magnetic coupling for motion transfer through the water tight boundary of the meter [23]. The magnetic coupling is either tracked with follower magnets to increment a mechanical volume register or counted with a reed switch or similar pulse generating device in the meter's display.…”

Resource conservation decisions require detailed consumption information. This paper presents sensors and signal processing techniques that use pipe vibration signatures to non-intrusively identify water consumption at the appliance level. The method requires as little as one easily installed vibration sensor. This method provides a no-fuss retrofit solution for detecting the operation of a building's water consuming appliances. In addition, flow rate is nonintrusively obtained from a conventional water meter via a new, high sensitivity strap-on magnetic sensor. Together, these two sensors track load operating schedule and water consumption in a building, demonstrated here at three different field test sites.

“…Devices like digital loggers, ultrasound, static, or electromagnetic, together with computer software, make it possible to quickly display detailed monitoring data. The benefits of such methods are significant, including determination of correct water meter selection in a given building or determining the efficiency of internal water supply systems [1][2][3][4][5][6][7][8].…”

Abstract. Measuring instruments are designed to measure a given physical value, to process the obtained information and forward it to the observer. They are designed to perform specific tasks in specific working conditions and meeting the envisaged requirements. The most important requirement to be met by measuring instruments, is to preserve the established metrological characteristics. The basic and most common instrument for measuring the volume of flowing water is the water meter. Selecting the right water meter in the operating conditions is not an easy issue. The problem has been further intensified by decrease of water consumption which began in the 90s of the twentieth century and continuing to the present day. As a result, there has changed the structure of water consumption in both the residential and industrial applications. In this situation, a right selection of the optimal water meter it is an important case.The article presents the results of research in the field of characteristic flows in the water supply connections in multi-family housing using modern monitoring systems. It has been presented the calculated inequality ratio of water consumption, which can be helpful when designing a plumbing systems. In addition, the structure of water consumption due to the typical flow ranges was determined.

“…Other standards refer to the same recommendations as well [4,5]. Based on that [6] recommends the following: "Should there be doubts about whether the operation time of the valve affects the results of the tests, it is recommended that the tests should be made longer, and never under 60 seconds". Therefore by standards, errors induced by valve operation are treated only by calibration of the water meter.…”

Original scientific paper In order to ensure the same conditions as for flow calibration, in case of a single-person household provided with a class B multi-jet propeller water meter with nominal diameter of 20 mm, a thermally insulated storage tank was built. During the exploitation, the storage tank will be fed by calibrated constant discharges in stages. For the purposes of measured consumption cumulative curve, the needed tank volume, flow rate and minimum duration of the filling stage were defined in the function of water meter reading accuracy (1 litre, 0,1 litre and 0,025 litre). The measurements proved that the thermally insulated tanks were able to keep water temperature within the range identical to that measured in the water supply in a single-person household. Keywords: single-person household; storage tank; water meter calibration; water meter reading accuracy; water temperatureRezervoar za samačko kućanstvo koji osigurava uvjete protoka jednake kao pri baždarenju vodomjera Izvorni znanstveni članak Za osiguranje jednakih uvjeta mjerenja utroška vode kao pri baždarenju, za samačko kućanstvo s višemlaznim propelernim vodomjerom nazivnog promjera 20 mm, klase B, izgrađen je termoizolirani rezervoar. Tijekom rada rezervoar će se puniti konstantnim, baždarenim protjecajem u fazama. Za izmjereni hidrogram utroška, potreban volumen rezervoara, protok i minimalno vrijeme trajanja etape punjenja utvrđeni su u funkciji točnosti očitavanja vodomjera (1 litra, 0,1litre 0,025 litre). Mjerenjem je dokazano da je termoizolirani rezervoar osigurao očuvanje temperature vode u području temperature identičnom onom izmjerenom u vodovodu samačkog kućanstva.
