Installation Instructions

This section discusses how to prepare the system and install a X-Flow™ mass flow controller.
2.1 Unpacking and inspection
Check the outside packing box for damage incurred during shipment. Should the packing box be
damaged, then the local carrier must be notified at once regarding his liability, if so required. At the same
time a report should be submitted to your Parker representative.
Carefully remove the equipment from the packing box. Verify that the equipment was not damaged
during shipment. Should the equipment be damaged, then the local carrier must be notified at once
regarding his liability, if so required. At the same time a report should be submitted to your Parker
representative.
Contact your local Parker representative or ppfinfo@parker.com for return information.
Before installing an X-Flow™, it is important to read the attached label and check:
- Flow rate
- Fluid to be measured
- Up- and downstream pressures
- Input/output signal (determined by the model code)
- Temperature
Inspect the X-Flow™ mass flow controller for damaged or missing parts.
2.2 Rated pressure test inspection
Each X-Flow™ is pressure tested to at least 1.5 times the working pressure of the process conditions
stipulated by the customer, with a minimum of 8 bar.
The tested pressure is stated on the flow controller model code sticker. Check test pressure
before installing in the line.
If the sticker is not available or the test pressure is incorrect, the instrument should not be
mounted in the process line and must be returned to the factory.
2.3 Instrument mounting
The bottom side of an X-Flow™ consists of four mounting holes for stable mechanical fixation of the
instrument. Two opposing mountings are suggested, one on the inlet and one on the outlet side of the
instrument. Refer to the following documents for exact position of the mounting holes:
Dimensional drawing 601XF, document A-4539 and Transition Plate dimensional drawing A-4540
The preferred mounting position of X-Flow™ mass flow controllers is horizontal. Other mounting
positions may introduce a zero shift and/or little gas and pressure dependency of the zero signal. When
mounting an instrument other than horizontal, zeroing of the instrument is advised. The zeroing
procedure is described in section 2.12.
Avoid installation near mechanical vibration and/or heat sources.
2.4 Fluidic connections
The inlet and outlet cavities/fluid connection ports of X-Flow™ instruments have 9/16-18 UNF-2B
(female) threads.
The instrument is shipped standard without fittings.
