This helps prevent selecting a similar-looking Flowline model with a different configuration.

Application and Installation Planning

For replacement work, record the existing model number and wiring or mounting arrangement before removal. For new projects, review the documented installation guidance and leave adequate clearance around the sensing area. Commission the device using the applicable Flowline instructions and verify the output or switching behavior before returning the process to normal operation.
