Differential Pressure Flow Switch BWFS10 Overview
BWFS 10 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. Our 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.
