    In this manual, you will find all the information you will need to commission the nanoFlu. Technical specifications as well as detection limits and the dimensions can be found in chapter 7.

  • Page 5: Health And Safety Information

    Devices that radiate strong electromagnetic waves can influence the measurement data or result in a malfunc- tion of the sensor. Avoid using the following devices in the same room as the TriOS sensor: mobile phones, cordless phones, transmitters/ receivers and other electrical devices that produce electromagnetic waves.

  • Page 6: Warnings

    Make sure that the cord is not run near hot surfaces. • If the sensor cord is damaged, it must be replaced with an original part by the customer service of TriOS Mess- und Datentechnik GmbH or by an authorized TriOS technician.

  • Page 7: Disposal Information

    The use of other media can damage the sensor. For the use of the nanoFlu in other media than those specified in this manual, please contact the customer service of TriOS Mess- und Datentechnik GmbH (support@trios.de).

    Product type Power supply Interface In addition to the product bar code, the rating plate includes the TriOS Mess- und Datentechnik GmbH logo and the quality label. Please note that the specifications given here are for illustration purposes only and may deviate depending on the version of the product.

  • Page 9: Measurement Principle And Design

    Filter Lens Photodiode Essentially, the nanoFlu consists of four parts: a defined light source, a lens system, the optical path and a detector with ambient light suppression. The arrangement of these parts is represented schematically in the above illustration. The light source consists of an LED with a defined wavelength depending on the version or parameter.

    2.4 Browser nanoFlu is equipped with a web interface, which can be used to configure the sensor. To access the web inter- face, you will need the G2 interface box and an Ethernet-capable device with a web browser, e.g. a notebook.
  • Page 11 In the menu on the left, the subpoints are listed. There is a “Help” link on the right side that will take you to the TriOS Mess- und Datentechnik GmbH website. An active Internet connection is required to access the website.
  • Page 12 On this page, it is also possible to scale the measured value with the help of entries for “Offset” and “Scaling”. The new measurement can be triggered at any time. To do this, click on the “Measure Now!” button. A new measurement will then be carried out with the saved settings. D01-060en202008 Manual nanoFlu...
  • Page 13 If the previous measurement has not yet been completed after the interval has elapsed (e.g. because the nanoFlu simply needs more time to calculate the average), this previous measure- ment will be waited out before the next one is started.

  • Page 16: Interfaces

    3.2 Interfaces 3.2.1 Serial Interface The nanoFlu provides two lines for digital, serial communication with a control device. It is equipped with a configurable digital serial interface as RS-232 (also EIA 232) or RS-485 (also EIA 485). The interface cannot be switched and is already defined when delivered.

  • Page 17: Network

    Network with a single G2 sensor The easiest way to connect to the nanoFlu is with the G2 interface box. It serves as both the connection and the power supply for the sensor and can be used with all TriOS G2 sensors.
  • Page 18 URL options. Automatic measurement by the nanoFlu is stopped when an Ethernet-capable device is connected. As soon as the LAN connection between the sensor and the Internet capable device is disconnected, the measurements will be continued at the set interval if the timer is activated.
  • Page 19 Like any G2 sensor, the nanoFlu delivers a simple DHCP server as well as a simple DNS server, which is con- figured exclusively for direct connection, as described in the previous section. For a complex sensor network, the servers must be supplied by the user.

  • Page 20: Use

    4 Use The nanoFlu can be operated with all TriOS controllers. Instructions for correct installation can be found in the controller manual. 4.1 Normal Operation 4.1.1 Immersion Operation For immersion operation, the nanoFlu can be completely or partially immersed in the water / measuring me- dium.

  • Page 21: Flowcell / Bypass

    4.1.3 FlowCell / Bypass With the optional flow cell, the nanoFlu can be installed as a bypass. For this purpose you need the nanoFlu FlowCell (Art.No.: 10A090000) and a nanoFlu with a special housing, which was especially designed for the operation in the FlowCell (Art.No.: 32SX03X10).

  • Page 22: Calibration

    5 Calibration 5.1 Manufacturer Calibration All TriOS sensors are delivered calibrated. The calibration factors of the nanoFlu are stored in the sensor, meaning that all values that are output are calibrated values. The conversion from the original measurement parameter to the scaled measurement parameter is carried out by means of the following equations.
  • Page 23 Local calibration is adjusted by means of a linear equation. Two constants are required for this: the scaling factor and offset, which are used according to the following equation: A = parameter - offset B = A ∙ scaling With A being the parameter output, which is output by the nanoFlu. offset corrected value offset value Offset customer-calibrated parameters For local calibration, at least two data points, i.e.
  • Page 24 The offset can also be found using the abscissa of the straight line (intersection with X axis). For the above example, this means: 90 - 30 scaling factor = 40 - 20 offset = 40 - = 40 - 30 = 10 D01-060en202008 Manual nanoFlu...
  • Page 25 Measured concentration [µg/L] All TriOS controllers have the ability to set scaling factors and offset values for the measurement parameters. Please refer to the appropriate manual. Make sure not to carry out double scaling with the sensor: once in the...
