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.
