 nanoFlu

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. To make a correct measurement, the measuring window must be completely immersed and free of air 
bubbles. nanoFlu can also be attached with suitable hydraulic clamps. Make sure to use suitable brackets with 
an inner diameter of ~36 mm. To protect the housing pipe against excess punctual pressure, install the brackets 

close to the device covers. Fitting brackets can be obtained from TriOS.

When immersing the sensor, make sure there are no air bubbles in front of the sensor discs. 

If there are air bubbles in front of the window, shake the sensor carefully until the bubbles 

have been removed.

4.1.2 Float

nanoFlu can also be used in a float, which is particularly useful in case of fluctuating water levels.
