  • Page 29 flowIQ® 3100 TECHNICAL DESCRIPTION Info code - BURST This info code is activated if the flow exceeds a given value for a continuous period of 30 minutes. This can be a sign of a burst in the pipe installation which requires prompt action. The size of the 30-minute flow (which prompts the info code BURST) can be determined by the customer when submitting the order, and later by Metertool.
  • Page 30 Info code – RADIO OFF (transport mode) This info code is active in the display when the water meter leaves Kamstrup A/S, and indicates, that the ete is still i t a spo t ode a d that the uilt-in Wireless M-Bus radio transmitter has not yet been activated.

  • Page 43 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 44: 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 45 flowIQ® 3100 TECHNICAL DESCRIPTION In principle, flow is determined by measuring the flow velocity and multiplying it by the area of the measuring pipe:   where: Q is the flow is the flow velocity is the area of the measuring pipe The area and the length which the signal travels in the sensor are well-known factors.
