Description
Fixed Water Differential Pressure Flow Switch/Sensor
BWFS**0
The *0 series differential pressure flow switch with single fixed
set point was
designed for OEM customers. It was designed to be compact,
cost-effective,
differential pressure switch for application such as proof-of-flow,
filter
monitoring, etc. The pre-setting value can not be changed, which
can ensure
the flow setting value can not be changed. ACOL company
considerate
the practical situation, can transfer the setting differential
pressure value to
the flow protection value of the heat exchanger. The value can set
by our
professional according to customer’s requirement and print on the
label.

The pressure difference will increase with filtering, switch is on
and output a signal when reached the pre-pressure
value. If it automatically clean, the signal would be transmitted
to controlling disk and then the controlling disk start to
clean and open the waste valve. If worker to clean, the warning
signal will remind operator to clean.
