Operating principle / fast changes in flow velocity
When the flow rises, the output switches when the trigger point (TP) has
been reached.
When the flow falls again, the output switches back when the value "SP
minus hysteresis" has been reached.
If SP is not reached within a short time*, the output switches back immedi-
ately (*approx. 1s; depends on the application and the and the operating
range of the sensor).
Operating principle / slow changes in flow velocity
When the flow rises, the output switches when the switch point (SP) has
been reached. When the flow falls again, the output switches back when the
value "SP minus hysteresis" has been reached.
