Density Of The Measuring Medium - KEM FAU 50 Manual

Density of the Measuring Medium

In case you selected a volumetric unit under chapter 3.1.2, the FAU will now skip this parameter. However, with
mass-related units the FAU requires you to enter the density of the measuring medium.
KEM Flow Meters detect the volume flow. The FAU can calculate the corresponding mass flow considering the
density, provided that the density is constant.
Example: the density of the measuring medium is 1,250 kg/m
Enter with , after that the next parameter appears.
Gate time
The parameters "Gate time" and "Gate memory" enable you to adapt the temporary transmission behaviour
between frequency and analogue output to your requirements.
After the gate time has passed, the FAU calculates an average frequency for the measuring interval thereby
calming signal fluctuations.
Periodic disturbances, e. g. pressure fluctuations, will be included in the displayed values, if the gate time is too
short. You may avoid this by chosing an appropriate interval.
Example: flow variations with a period of 0.5 seconds require a gate time of ≥ 0.5 seconds.
You may chose a gate time from 0.10 up to 3.5 seconds in steps of 104 milliseconds. Enter your setting with
and the final parameter of the K-factor level will appear.
