When the flow rises, the output switches when the switch point
(SP
) has been reached.
Flow
When the flow falls again, the output switches back when the value
"SP
minus hysteresis" has been reached.
Flow
The hysteresis is considerably influenced by the choice of the operat-
ing range on the sensitivity curve of the sensor:
• In the case of adjustment to HI-Flow values in the range 0 ... 60 cm/s
the hysteresis is 2 - 4 cm/s (values apply to water).
• In the case of adjustment to HI-Flow values above 100 cm/s the
hysteresis increases as the flow rises.
Hysteresis function temperature
When the medium temperature rises, the output switches when the
switch point (SP
When the medium temperature falls again, the output switches back
when the value "SP
The hysteresis for temperature is 2°C.
