7.2.1. Measuring range chart
Reference conditions: acc. IEC 770
Water 20 °C; air 1,013 bar abs.
1)
for BGN-P version (PTFE), float with tantalum collar, measuring cone made of borosilicate glass
measuring range: A 0.7
–7.0 l/h, B 1.2–12 l/h, C 2.0–20 l/h
2)
gas throttle in S version for gas measurement included in price (pressure loss 200 mbar)
3)
not available in P version
4)
sizing for higher viscosities not possible
5)
only in S and H version, only with reduced sealing face
6)
gas measurement not possible
7)
with only atmospheric pressure a measurement is not possible. Indicated values are for orientation. For gas measurements
a factor of 2-3 of the inlet pressure should be considered
8)
Restrictions for units with PTFE lining

Output signal / electrical equipment / options
Inside the indicator housing different electrical
switches (max. 2) or transmitters may be mounted.
8.1
Binary output
By using the segment disks (double or single) for to adjust the proximity switches or by using excenter discs for to adjusted the
micro switches, any switching point between 10% and 90% of the flow rate can be set.
8.1.1
KEI 1 or KEI 2 limit switches
1 or 2 limit transducers,
Model SJ 3,5N, manufacturer Pepperl & Fuchs (special switches e.g. safety technology or 3-wire version possible)
Safety class:
PTB Nr. 99 ATEX 2219 X
