This Kit consists of an additional IP65
housing mounted aside the sensor via a
PVC plate. It is equipped with an open
collector frequency output and a
mechanical SPDT contact. The MIN alarm
set-point can be freely set by a
potentiometer up to 21 l/h (0.09 gpm) for
ULF01 and 53 l/h (0.23 gpm) for ULF03.
When the flow velocity drops below the
adjusted limit the relay output opens and
the Local Status Indicator changes colour.
It has been designed to protect a pump
from running dry or pumping against a
closed valve in the main pipeline.
