shell code
>c<
For unequivocal identification of the sensor’s attendant measuring ranges, each sensor
dimension on the protective cap of the upper shell is supplied with the relevant letter
(e.g. >c<),
in order to avoid erroneous settings in the central building control system or the optio-
nal portable measuring device (Figure 138 00 002).
Example: shell code >c< indicates a DN 20 sensor size (or valve size) with a measurable through
-
flow of 3.5 – 50 l/min. and a frequency f of ca. 21…279 Hz.
