Detector Diversion and Bypass: Delay Volume and Switching Disturbance

01Locate the source, drive and receiving position for this task

Define all ports, valve states, pressures in each state, shared volume and displacement volume. Follow the diagram to confirm liquid contact, pressure and destination before assigning drive and connection roles.

02Define switching windows from delay volume

Estimate arrival from the target liquid segment, flow and path volume, then establish switching windows using actual signals. Destination resistances differ; confirm actual pressure and permitted disturbance for each.

03Compare product options against task requirements

The following candidate options match this page's responsibilities. Compare them against the operating conditions described, then check capacity, materials and interfaces on the product pages. Card images show representative configurations; suitability must still be confirmed at actual operating points and by application results.

04Associate detection state with liquid-segment destination

Associate detection state with valve position and identify the target segment before switching. Define the default destination during maintenance or faults to prevent unsuitable liquid entering the detector.

Action records should link commands, valve or interface states and actual received results. When raw material, container or sample identity changes, reconfirm shared paths and conditions permitting the next step. Completion of drive movement alone does not replace task acceptance.

05Check pressure transients and baseline recovery

Measure actual arrival, switching loss, pressure transients and baseline recovery. Timing estimates support design; acceptance depends on retaining the correct detection segment and routing waste correctly.

Record test medium, configuration, installed path and operating sequence; present routine operating points and boundary results separately. Calculations support design discussions, component documentation checks models, and installed measurements confirm the actual task.

06After an abnormality or maintenance, first identify which segment needs recovery

Mispositioning, shared-path residue or abnormal switching pressure can affect the next task. Stop pumping and check ports, then flush again after restoring the correct state.

Retain current source, container identity, completed actions, valve or interface state and actual receiving information. Use the table to locate the stage that changed before deciding to retry, continue or restart. After recovery, recheck the relevant operating point before returning an uncertain action to the automatic cycle.
