unit may be damaged or fail prematurely. Such damage will not be
repaired under warranty.
Units should be installed in a clean, dry environment with an ambient
temperature that is as stable as possible. Avoid areas with strong magnetic
fields, strong air flows or excessive vibration.
In order to operate the differential pressure across the controller should be
in the range 15-45psid (1-3 bar). For optimum performance a differential
pressure of 25psid is recommended.
For Example, consider the following system:
The differential pressure across the flow controller in this system would be
100 psi – 14 psi = 86 psid. Consequently the flow controller would NOT be
able to control flow. For the unit to operate at optimum performance the
supply pressure from the gas cylinder would need to be lowered to 39 psig
to give 39 psi -14 psi = 25 psid.
