    Before operating the device the user has to ensure, that the local regulations (e.g. for operation in channels) on installation and initial start-up are taken into account, if this is both carried out by the user. NFP - Rev. 02 as of 24.11.2009 page 11...

  • Page 12: Functional Principle

    Instruction Manual Functional Principle General The NFP is a permanent measurement system for flow measurement of slightly to heavily polluted media with various consistencies in constantly full filled pipes. The method of flow velocity investigation is based on the ultrasound reflection principle.
  • Page 13 Echo signal images and evaluation Based on the beam angle, the interval between both transmitted signals and the lag of the signal pattern therefore in each single measurement window the flow velocity can be determined. NFP - Rev. 02 as of 24.11.2009 page 13...
  • Page 14 From this velocity multiplied by the circular pipe area we can obtain the flow rate. This rate can either be a free programmable analog signal or an impulse signal as well. page 14 NFP - Rev. 02 as of 24.11.2009...

  • Page 15: Device Versions

    ® Instruction Manual Device Versions The NFP transmitter as well as the accompanying flow velocity are available in different versions. The transmitters primarily vary in terms of maximum pipe diameter, power sup- ply, Ex-protection as well as the number of analog outputs.

  • Page 16: Storing, Delivery And Transport

    Please check your delivery according to the delivery note for completeness and intactness immediately after receipt. Any damage in transit must be instantly re- ported to the carrier. An immediate, written report must be sent to NIVUS GmbH Eppingen as well.

  • Page 17: Installation

    For electric installation the local regulations in the respective countries (e.g. VDE 0100 in Germany) must be referred to. The NFP power supply must be separately protected by a 6 A slow-blow fuse and has to be isolated from other facility parts (separate turn-off, e.g. by using an automatic cut-out with >B<...

    To be able to use cable diameters outside of the tolerance, glands must be used which ensure IP 65 minimum protection. Unused lead-ins have to be locked with an appropriate dummy plug before the initial start-up. NFP - Rev. 02 as of 24.11.2009 page 19...
  • Page 20 Instruction Manual Each time before opening the terminal clamp housing (see Fig. 2-1) please ensure to disconnect the NFP from any voltage. It is not allowed to remove the front panel. Before the first connection it is necessary to have a slight pressure on the screw of the clamping connection to ensure its safe opening and a correct connection.

    Instruction Manual NFP Power Supply Depending on the type of NFP used, it can be supplied with 100-240 V AC. Also possible is a 24 V DC supply (see chapter 4.2). The two slide switches located above the terminals serve as additional power switch.

  • Page 24: Overvoltage Protection Precautions

    Fig. 6-7 DC model power supply Overvoltage Protection Precautions For effective protection of the NFP transmitter it is necessary to protect power supply and mA-output. NIVUS recommends surge arrestors types EnerPro 220Tr bzw. EnerPro 24Tr (for 24 V DC) for the mains supply, as well type 2x1 24/24 Tr for mA-outputs.

  • Page 30: Parameter Setting

    Please observe the bottom line of the display whilst programming, indicating the required measuring unit! This instruction manual describes all programming options of the NFP. Depending on the device type however there might be only one analog output available or the maximum pipe diameter to set might be 450 mm (see Fig.
  • Page 31 In the basic setting the transmitter operates with a nominal diameter of 250 mm. The NFP will indicate a flow rate if there is a flow velocity prevailing at the mo- ment of initial start-up and the sensor has been installed correctly. This reading of course is not yet relevant to the current application.
