    8.1 Level measurement applications Positioning The optimal location for NRE-4/NRE-6 (for a cylindrical tank) is at radius r = (0.3…0.5) R. It is always advisable to consider the radiation cone angle. The liquid surface must be perpendicular to the axis of the device.
  • Page 8 It is essential to avoid objects (pipes, ladders, structural elements, thermometers, etc.) entering the radiation cone. CAUTION! If necessary, programming can block up to 4 interfering echoes in the NRE-4/NRE-6 threshold settings by programming! ALIGNMENT The plane of the process connection must be parallel to the measured surface within ±2…3°.
  • Page 9 The sensor must be protected from direct sunlight to avoid exceeding the highest permitted temperature. FOAM Foam on the measured surface may prevent millimeter-wave level measurement. The sensor should be mounted in a position below which the formation of foam is the smallest. NRE-4/NRE-6 K02/0624 page 9...

    The NUS-NTB_NRM-SW software supports both modes. In accordance with the Rosemount Standard, HART® communication can be used between the NRE- 4/NRE-6 as a “slave” and the HART® master as a point-to-point connection. Communication can be implemented in two modes. If the device is set to current In the case of a multidrop operation (4 mA), several transmission (4…20 mA, “0”...
