DEFINITION

Classification: 137/115.01

Bypass or relief controlled by main line fluid condition:

(under subclass 109) Subject matter including a flow line with an inlet and outlet for a main flow and an outlet branch or bypass in which the flow is controlled in response to a variation in the fluid condition (e.g., fluid level, flow rate or pressure, or the like) in the main flow line detected by a sensor.
