Max Line Pressure for Model 231

The max differential pressure you can measure is the max line pressure the unit can see. This is independent of the range code A through D you select.

For example:

• the Model 231GMS2 has a max differential pressure of 100PSID, so the max line pressure is 100PSI.

• The Model 231GMS1 has a max differential pressure of 50PSID, so the max line pressure is 50PSI
  

  • If you select range code D (5PSI) on an MS1, the max line pressure is still the max differential pressure of 50PSI.
