Differential Pressure Flow Switch 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.
