  • Page 32: Installation

    When mounting the water meter, you must ensure that the length of the meter thread will not prevent sufficient tightening of the sealing surface, and make sure that PN10 or PN16 connections are used. Kamstrup A/S recommends EPDM-gaskets for cold water installations and PTFE-gaskets for hot water installations. Kamstrup A/S supplies such gaskets.
  • Page 33 Installation conditions As mentioned above the use of new gaskets in original quality is of crucial importance. The sealing surface of the threaded connection must be clean and level ALWAYS use new gaskets. Kamstrup A/S •Technical Description • 5512-897_J1_GB • 06.2016...
  • Page 34 In such cases, Kamstrup A/S recommends to install the meter by means of a special coupling with telescopic function.

    When the meter switches to ‘verification mode’, the wireless M-Bus radio transmitter turns off. At the same time, a time-out starts. When the time-out period has expired the meter switches back to normal mode. The time-out period is 9 hours. Kamstrup A/S •Technical Description • 5512-897_J1_GB • 06.2016...

  • Page 53: Legal Changes Outside Seal

    The meter is initially verified from the factory. A new factory adjustment requires disassembling of the meter and can only be carried out by Kamstrup A/S. When the meter has been locked it is only possible to make a percentage correction of the flow curve at three individual points. This is called re-adjustment.

  • Page 55: Measuring Principle

    Flow sensor manufacturers have been working on alternative techniques to replace the mechanical principle. Research and development at Kamstrup has proven that ultrasonic measuring is the most viable solution. Based on microprocessor technology and piezo ceramics, ultrasonic measuring is not only accurate but also reliable.
  • Page 56  To minimize the influence from variations of the velocity of sound in water, the latter is measured via absolute time measurements between the two transducers. These measurements are subsequently in the Kamstrup A/S •Technical Description • 5512-897_J1_GB • 06.2016...

    The measurement is therefore a 'snapshot' of the current flow. This, like any type of digital sampling, integrates the measurements over time, leading to the calculation of the final volume. Flow [l/sec.) Time [seconds) Kamstrup A/S •Technical Description • 5512-897_J1_GB • 06.2016...

    The meter has no functional limitations during the period, when the meter operates above this limit. Please note, however, that high flow velocities > Q (Max flow) involve the risk of cavitation, especially at low static pressures below 0.03 MPa (0.3 bar).
