  • Page 27: Functional Description

    The NivuFlow 600 is used in fully filled channels and pipes of various geometries and dimen- sions. The two points of measurement of types T4 and TM are primarily used to carry out measure- ments at two different points within a channel.

  • Page 28: Functional Principle

    There is no measurable flow available. The NivuFlow 600 works with both clamp-on sensors and wetted sensors. The clamp-on sen- sors are installed on the outside of the pipe. In this case the transit time through the pipe wall is calculated and considered.

  • Page 29: Flow Calculation

Sensor 1, path 1 Sensor 2, path 1 Sensor 1, path 2 Sensor 2, path 2 Pipe diameter (at sensor installation in an angle of 45°) Fig. 19-2 Two-path transit time measurement principle If the sensors are installed in an angle of 45°, the distance between sensors 1 and 2 or sen- sors 3 and 4 is equal to the inside pipe diameter.

  • Page 30: Installation And Connection

    NivuFlow 600 Type E0 not suitable for installation in NIVUS field enclosure It is not possible to install a NivuFlow 600 Type E0 in a NIVUS field enclosure unless the transmitter is converted to a Type E1 unit. The conversion and the modification of connec- tions can be carried out by NIVUS.

  • Page 31: Choosing The Installation Place

    Make sure that any existing disconnectors (power switch) remain easily accessible during installation. The measurement transmitter can also be installed in field enclosures or similar. NivuFlow 600 is not suitable to be installed directly on site without protective measures due to protection class.

  • Page 32: Field Enclosure Fastening And Preparing Electric Installation

    The fastening material is not part of the standard delivery but should be specified and chosen individually depending on the place of installation. The NIVUS field enclosure can be installed permanently once the appropriate place of installa- tion has been chosen. A basic condition is safe, durable and stable installation.
  • Page 33 Readability may be strongly impai- red due to the changes to the protective film. New clear view covers can be purchased from NIVUS for an extra charge and can be easily replaced by the user.

    Overvoltage protection for (transit time) sensor connectors 23.4.1 Basic protection - equipotential bonding cable NIVUS recommends that an equipotential bonding cable is used to connect the sensor enclo- sure to the control cabinet/transmitter ground as a basic protection measure for the transit time sensors’...
  • Page 52 The “EnerPro” overvoltage protector may also be installed inside the control cabinet, but the separate earth connector “G” must be retained. The combination with “P” or “C” is very risky in the event of overvoltage. NIVUS recommends that the earth connectors are separated to guard against overvoltages.
  • Page 53 Installation and Connection If it can be assumed in applications that no overvoltages can be induced from the sensor side, there will be no leakage currents through the earth connection “P”. This can then be tied directly to the transmitter grounding “C”. All other input/output signals and input/output voltages leaving the control cabinet must also be considered in relation to overvoltages.

  • Page 54: Operation Start-Up

    The user interface of the NivuFlow is easy to understand. Users can make all required basic settings themselves. In the case of the following requirements let either one of the legally associated companies or subsidiaries of NIVUS group or an expert company authorised by NIVUS set the parameters: • Extensive programming tasks •...

  • Page 55: Operation Basics

    Operation start-up 25 Operation Basics The complete operation of the NivuFlow is handled via control elements (see Sect. “2.2 NivuFlow Operating Elements”). Two control buttons and one rotary pushbutton are available for the setting of parameters and to input required data.

    Setting Parameters 32.2 Total The totals, divided into positive and negative totals, for the respective measurement points are displayed. In addition, the resettable totals are displayed and they can also be reset using the >Reset total< button. The individual measurement points are shown at the top right of the display. You can scroll between the measurement points with the Tab key.

If the transmitter should be shut down between two totalising events (< 24 hours) a total will be calculated by using measured values. Such a total is not equal to the real daily flow rate but corresponds to the rate measured by the transmitter while powered up.
