3.4 Pre-installation requirements
The sensor can be installed into the SENSOFIT FLOW 1000 assembly which is available in DN32,
DN40 and DN50.
If installed into small diameter pipes like DN32 and DN40 the minimal free diameter of 20 mm
around the sensor coils can not be kept. In these cases the cell factor has to be adjusted. The
best method is to do an inline calibration against a reference measurement. In case this is not
possible try to achive similar dimensions and materials in a calibration beaker. In case both is
not possible you can adjust the cell factor by multiplying it by a factor. Every sensor coil is
different or might vary in its characteristics. A multiplier can only be given as an approximate
indication. Within a SENSOFIT FLOW 1000 with DN32 you do have ~8mm and with DN 40 ~14mm
free space around the sensor available, both being less then 20mm. Mentioned multipliers are
approximates only. Therefore the recommendation is to install in a pipe equal or bigger then
DN50.
Multipliers for cell factor correction depending on pipe dimensions
CAUTION!
•
Unpack the sensor carefully!
•
Make sure that the sensor is clean.
INFORMATION!
•
Nothing shall block the measurement hole within the sensor.
•
Consider a large enough distance from metal or plastic pipe walls!
