    2. Technical data: reference standards and regulations The technical data is specified in the Technical Data Sheets issued for specific water meter types. The water meters meet the following standards and regulations: 1. Directive 2014/32/EU of the European Parliament and of the Council of 26 February 2014 on the harmonisation of the laws of Member States related to the making available on the market of measuring instruments 2.
  • Page 8: Operating Principle Of Water/Flow Meters

    3. Operating principle of water/flow meters The MWN (WPH-01) Nubis water meter comprises a body, metering unit, and counter mechanism. The flow of water passing through the water meter drives the propeller installed in the metering unit. The propeller is co-axial to the body bore and rotates a magnet on an axle via a worm and wheel transmission.
  • Page 9: Selecting The Correct Size Of The Irrigation Flow Meter

    A water meter that is too small overstresses the mechanism, resulting in premature wear of the moving components. For your water meter to perform properly within its measurement range limits and maximum indication error limits, its operating range must be precisely determined, which can also be achieved based on monthly water demand, considering the minimum and maximum volumetric flow values (for existing installations, it is recommended to monitor the water supply).

Delivery inspection The measurement device as supplied by the manufacturer requires inspection to verify that no external shipping damage is present, especially on the body, the body flanged ends, the counter guard, and the wiring (if the version includes a transmitter module).

  • Page 12: Irrigation Flow Meter Installation Requirements

    7.7 Prevent overstressing of the water meter due to the attached piping or other equipment. If necessary, install the water meter on a pedestal or a bracket. The upstream and downstream piping must be properly fastened so that no component of the system shifts by the action of water when the water meter is removed or detached on one of its ends.
  • Page 13 8.2 Install stop valves upstream and downstream of the irrigation flow meter connections to enable isolation from the water for removal of the irrigation flow meter or its measuring insert for inspection or repairs. 8.3 The piping route geometry at the installation location must prevent air blocks from forming within the installation length of the irrigation flow meter.

    9. Priming with water, commissioning, and operation of the water/flow meter 9.1 Before installing a water/flow meter in the piping, flush the piping to remove all debris and contamination. If a filter is to be used, it must be cleaned before the installation process. For the flushing process, the water/flow meter must be replaced with a straight pipe spool.
