The contact is normally closed. In case the actual flow is less, than the preset low limit
(
QL
)
, or the actual flow is higher, than the preset high limit
(
QH
)
, the contact brakes.
OUT 4
Programmable current output proportional to flowrate
Current range:

(
Io…Im
)
Flowrate rang:
the measuring range
(
QIo, QIm
)
Load:
0…500
